- The folks at Holley Performance Products were kind enough to send us a Terminator EFI, which we recently installed in Hagerty Parts Finder Davin Reckow's classic Chevelle. We test the impact on performance via the "butt dyno," the 1/8th-mile drag strip, the chassis dyno and gas mileage. Subscribe! | bit.ly/1sddOmD

STOP PLAYING MUSIC OVER THE ENGINE ROAR.
make your own videos and you can do that all day long
Lawrence exactly !!!!!!!! I agree cut the music over engine
Its like a band called engine roar.
Yeah, I don't get why so often videos like this have music playing when they're running the car...the whole point is to hear and see the car perform!
@@relco9825 Do what?
Doesn't play music, starts car, music starts... Why do you All do that? I'd rather head the car than you talking, I'd rather hear the engine and read subtitles than listen to you or your music.
Ha, ha... that is so funny. I was thinking the same. Saw another vid the other day- a hot rod Nova. You could barely hear the engine. Wahhas tha point, bro. Everybody's a video editor, now.
hey Rob, how about you make videos where its just engine noise and subtitles. Then you can watch your own videos that you actually put any work into, instead of bitching at someone else for their creative differences. Y O U W I L L F I N D A R E A S O N T O B I T C H A B O U T A N Y T H I N G
@@pedrogonzales9202 except you apparently
I love the old farts who say "What a waste. 20 minutes time and I could get that carb running better than the EFI garbage." They then get off of the computer, go into the garage, and hop into their 2014 Buick with their wife enjoying easy starts, good MPG, cruise control, A/C, and heated seats on their way to Denny's. All while leaving their carbed muscle car in the garage despite it being a lovely day. LOL.
I'm 37.... .I'm still building carbs. I love the sound, smell, and the initial throttle response of a carb. GET SOME!!!
You forgot to include increased engine wear with a carb.
Younger fart here. I have to agree with your old fart sentiment that 20 minutes is about all it takes to get the carb tuned up right. However, I have been driving my Nova for 15 years rain or shine as my daily driver, so I jump into it wherever I go!
I am so busted !
As usual some of you are missing the point of this. It wasn't to make more power, that was just a bonus. It starts better, has better driving manners, and gets better economy. If that's not what your looking for don't buy it, hell it's your money. I liked the video even though I don't plan on ever owning a carb'd vehicle again.
one word "driveability"
Greg Sikonia fuel injection is fine until it fucks up... then it's junk junk junk ....
I SpankEFI vehicles all the time with carbs including this small block SS clone ....
Whatever power your making with a carb, you could be making more power with EFI, his power level has nothing to do with EFI and everything to do with his intake, heads, cam and compression. It made 500ft-lb of torque at the wheels though, and that's excellent for what it has.
v8hotrodlincoln 500ft pounds to the wheels? You're joking right?
Just a basic screwdriver. (Uses welder, drill press, metal cutting press etc)
bigcheese82 lmao even had to send the tank out to have a return line bung welded in....
Exactly a lot more involved, and not everyone has a lift or a welder.
He did mention he would be using other tools to his disposal. There's really no excuse to not learn to weld these days and obtain the hardware. Shits cheap, maybe 25 years ago you'd have a point to argue.
That was funny. Granted not required per-say but a lot more than a screw driver.
@@CanadaBud23 , he mention a seeking a pro ,,, ?
you can clock your reaction time with a sun dial .
HAHA!
What does the reaction time matter on a comparison test with nobody in the other lane?
Has nothing to do with ET. Thats all they were looking for.
Chevy made some beautiful cars back in the day and certainly this '66 Chevelle is a representative of good design. This '66 is one of my favorite for it's style and looks alone and like the Chevelles from that era, definitely a hit for that big block 396. That EFI is amazing too!
What did it run in the Quarter mile with the carb and then with the EFI? I'm old school the hell with the eighth I'm a Quarter mile guy!!!!
shhhh they can't stay out of the sandbox...
Agree
@@fitnessguru8012 ,I'm with you Man. This 1/8 mile stuff ruined drag racing for me. I did a lot of drag racing in the 60's & 70's. The fast cars are finished so quickly it's boring!
@@kensnyder2340 I can outrun a slow car on foot in the first 5 to 10 yards, but not for 25 yards, and that makes a difference.
@@kensnyder2340 really. 1/8 mile? Race the damn pit bikes!
Love Michigan in warm weather, love 66 Chevelles,and want EFI sooo bad. Holley is at the top of the list when I decide to pull the trigger. Thanks for the inspiration, and the smoke and noise.

I was sick of pulling fuel bowls off constantly to make adjustments to fine tune the balance of street driving to WOT and having to make compromises to achieve the performance and streetability I was looking for. That was what pushed me into making this conversion. Running these systems also allows you to upgrade to a single plane manifold, in fact they even recommend having a common plenum for a more accurate vacuum signal to the MAP sensor. The wiring is easy, I used only a couple wires for the optional items while the rest is self contained so definitely do not be intimidated by that. The part of the install that took the longest was just the figuring out the routing of the harness to best hide it and cleanly integrating it into the factory harness. I chose a completely different route for fueling than an in-tank pump since I do have a return line but my tank has no baffling and could still suck air in certain situations with a less-than-full fuel level. Still have yet to drive it but I have started it and my goodness it was easy and the smell of vaporized fuel was no longer filling the garage after running it. I can’t wait to get it out on the road.
Cory Holbrook only thing make sure you angle. o2 sensor up cause if not you will burn thru them trust me there a joke on o2 sensor
@@myronkelly4496 that is with any O2 sensor. Moisture collects and fouls them out. Doesn't matter what O2 sensor, or brand of kit you go with, if you have it parallel to the ground or lower, that's an installation error, not a manufacturer error.
Every rig I’ve ever seen with the Holley efi system always has issues. A well tuned carb is way better IMO
I have seen a few with issues but most of them come down to improper install, usually wiring. Old school car guys think they can get away with janky wiring, which doesnt work with EFI. A well tuned carb is great but constant tuning for todays gas and conditions can be a hassle.
what was the size of the carburetor you took off and what was the size (cfm) of the efi unit? Were they the same?
Thats how you explain to hot rodders how much hp you had. How long a stretch of rubber u can make.
As someone who daily drives an 84 pickup that's carbureted I was seriously thinking about buying the Holly EFI kit, even had it in my shopping cart on Summit ready to buy, until I dug a little deeper. The pros are obviously mentioned everywhere: Tunes while you drive for maximum fuel economy and efficiency, better cold start up, no more having to deal with my manual choke, etc etc. But what they don't tell you is the cons. This is not an easy job that you can throw together. One thing they don't mention is you need to have a single plane intake manifold, or you need to cut and notch out your duel plane intake manifold, otherwise the Holly EFI will never run right. Duel planes are way more common, so you'd have to pull your intake manifold off and cut out and notch it and then put it back together. You can even see it in the HolyPerformance install video (even though they don't mention it). If you're half way into this project and didn't know that you'd be pretty pissed. And then there's the kicker, a properly tuned carb will run better and make MORE power than a Holly EFI kit. Holly even admits to this. So unless you're still in the build process or you have another vehicle to drive while you try to install this kit I would not recommend it. Go with a $150 wideband gauge and tune your existing carb. Hell I even added a $25 dollar flow through electric pump so when I let my truck sit for awhile I can prime the carb and it fires right up no problem
I had a 1986 k-5 blazer with the stock 350. It had a bad accelerator pump and a dead cylinder but no matter how long it sat you could bump the key and it fired right up. You’d have to feather the gas when you moved from a stop to get it to not stall but the thing would just fire right up and it would never leave me stranded. I miss that thing.
Sadly from 2030 on all those old combustion cars including classics will be banned
from public streets in entire EU and Scandinavia :-( In Germany the
Green Peoples Party gave order to shorten fuel supply from 2025 on by
reducing all conventional fuel stations to only one state operated
central gas station per city or county. Now they even want to slow down
all the gas pumps from 20 litre per minute to 2 litre per minute...From
2027 on in the EU certain car spare parts will be banned too....as
exhaust systems, turbo chargers and even some engine and gearbox
oils...California and New York will do the same from 2027 on.... So no
investments should be done in oil burning cars any longer....They even
created a new kind of crime here, called emissions and smoke crime. "Bundesabgasbespaßungsverbot" in German.
8th mile sucks
I really don't like the so-called purest. If it's your car number matching or not it's your CAR.
Well I thought this video was excellent. Just what I wanted to see. What was that? It was that the fuel mileage went up a whopping 20 percent but we forget that 14.6 miles per gallon still sucks. Now consider the simplicity of the carburetor and the complications of the EFI. I'll take the carburetor. Need more power? There's always NO2 or methanol/water injection. Cheers!
Watching install videos like this are annoying when they don't explain themselves. At the end of the install 9:20 they have ''a table full of parts'', one of which is the ignition system. If this was a ''kit'', why didn't Holley include a new distributor? Well at 8:58, you see they used a GM TBI type distributor for the ''plug and play'' ability (another mandatory item needed for this kit to work). Sure, this vid is 5+ years old but I'm just now getting back around to the idea of installing one of these. The bugs have had a while to be worked out by Holley so I'm looking forward to buying one.
20 yrs ago I had a 67 chevelle ss 396 bbc car
With a 454 block and 396 iron heads mild cam 3 in exhaust with turbo 400 transmission 3000 stall converter with 373 gears in a 12 bolt posi with a 750 carb that ran low 11s in 1/4 mile track nothing special
I think you need a new tuner and driver
Awesome video really looking forward to using fuel injection on my project. And 14 mpg with a big block major kudos
If it made a that kind of major difference. Then your carb was not operating correct. Switch does make big difference but not this.
I know this won't save gaz , that is not the aim here?But does this system put more in the carburator , than a regular carburator , without all this effort , and Chevrolet is not known to have starting issues , unless your in a cold fall night in Canada, lol ?
I installed this system into my 72 Mustang Conv, 351 4V car. All I can say is a Love it!! I also went with the phantom 340 in tank fuel pump, super easy to install and so far reliable. This was my first experience making breaded fuel lines, I think my fingers finally stopped bleeding :)
did you bread the fish and chips when you finished with fuel lines
I have the 72 Mach 1 also. Do regret making the change at all or totally worth it? Thanks
iv never had any real issues getting a carb dialed in, a wideband 02 gauge goes a long ways in making the most power with the best drive ability. i understand carbs a lot better than i do computer programs, the holley efi is a great system though.
Most people have NO IDEA that you can and in my opinion, should tune your carb with a wideband.
Wideband is the missing piece of carburetors if you ask me.
Kills me how many guys try to tune there carb off of smelling the exhaust pipes for a rich or lean mixture.
Maybe a trained blood hound could do that but no human is gonna know AFR from smelling the exhaust.
Carbs are a good way to make your engine run. Very primitive, but effective. However, EFI has so many benefits over a carb and unless you play with one, you will not even begin to understand. Besides, big oil companies are forcing you to convert with the fuel they supply...
I hate 1/8th mile. meaningless
I'd be interested to see this kit compared to a carb tuned properly with wideband air/fuel sensors.
Agreed. They should've at least tuned the hell out of the carb. After all, the TBI has a computer tuning it's optimum performance.
you can tune a carb all you want but in the end you can only put 1 static tune on a carbed motor whereas EFi learns and tunes the engine all the time while driving. Think about low vs. high ambient temps or low altitude vs. high altitude, clean vs. dirty airfilter. These variations will all be tuned out by the EFi.
EFi also does it's own cold start enrichment, no choke needed.
EFi is also able to cut off fuel when engine braking. It also controls idle speed dynamicaly (compensating for AC, alternator load, powwersteeringpump load.)
once you go EFi you won''t look back.
if you watch the building of a car on a 30 minute video,do you think it took 30 minutes to build the car?
sometimes you have to put your grownup hat on and make assumptions about things.
when one of these guys brings his car to the dyno,THEY TUNE THE FUCKING THING,
JET THE CARB,SET THE TIMING,THEN DO THE DYNO RUN .....you mindless moron.
Well considering pro stock is using it, I believe efi shits on a carb
@@mr.know_it_all totally different efi set up
I knew street chevelles that could beat 750 gsxr bikes in the 90s. This is NOT one of them.
I notice you didn’t fit a spacer on your in,et manifold as you did on the other video, interesting?🇦🇺🦘🦘
By far the best terminator review video on youtube to date. I love my system
Too much talking and too much music ... spoils the video ...

What should he have used to replace a carb ???

Chevelle's are like the Impala's little brother. I love full size muscle😆
Chevelles are intermediate
@@Moparmaga-1 pretty sure that's actually what he's saying, lol.
@@MikeW1981 sure except if you read what he said he said full size muscle which intermediates are not . that was all I was pointing out.
The only EFI kit id consider now a days is the FiTech GoEfi. Starts at $795.00 and you dont have to modify anything. ECU is self contained in the throttle body with the injectors. Comparing Fitech with Holley makes the Terminator look like an antique.
That's a damm good looking Chevelle
My buddy spent $3500 to lose 28 HP. It wasn't holley. I can't remember the brand
Fitech? Heard nothing really good about that system but it's cheaper.

Why did you have to take off the MSD box? I just put one on my car and was wondering if the EFI computer replaced it.... Thanks
Hey guys, great to see you doing another series. I've been a qualified mechanic in Australia for 15 - 16 years now and am a qualified LPG installer/ LPG RWC Inspector (LPG cars in Aust require a separate RWC for their LPG system itself) and RWC (Road Worthy Certificate) Inspector amongst other things and thought I'd chime in on the fuel tank issue. Firstly, I would NEVER recommend anyone doing their own welding on their car's fuel tank at home in their garages- BUT FYI- it's all about purging the tank clean of flammable gasses obviously. One method old timers used to use was to completely fill the tank with water to push all the air out and then go about cleaning and drying the tank prior to commencing welding but these days we use an inert gas to purge the tank clean thoroughly, then clean for welding. THIS IS NOT A JOB FOR THE HOME MECHANIC, NO MATTER HOW EXPERIENCED. THIS IS A WORKSHOP ONLY REPAIR, IN MOST PLACES MANDATED BY LAW.
Nothing was said about a distributor swap why did that happen
Why did you change the ign' timing, thought you were gonna come pair them straight up!?
A waste of car and money on rich brats.
What does the car do on racing slicks?
Those times are in the 14’s for a 1/4 mile, not very impressive considering the power. Tires were really holding back good drag times. The fuel economy was much better and that was at the top of my list when I bought my 69 Dodge Charger with the Hemi pkg and 4:88 gears in the back.😳😬😁
"The fuel economy was much better and that was at the top of my list when I bought my 69 Dodge Charger with the Hemi pkg and 4:88 gears in the back"
You opted for heavy car like Charger with a Hemi plus 4:88 gears and you are worried about fuel economy? HELLO!!!!
Was enjoying it and then they said "northern Michigan dragway" Brian ledford owns it im racing there tommorrow!!!! holy hell!
This gets the job done. It's no contest with a modern engine and trans from say an SS or LT Camaro swap. The V6 will do 320 hp and 20+ mpg and the 6.2 will do 420 hp and 17+ mpg. That's with fudging the mpg numbers down. An 05ish truck 5.3 is nice as well. 290ish hp 18 mpg and a wrecked truck can be bought for under a grand. Less performance. Budget option.
I think this was the perfect before and after test because most guys don't have a perfectly tuned carburetor. So a carburetor can do better but I think this was very representative of what you're going to find for the average street car with a carburetor . Excellent job 👍 Thank you
If I had a 396 Chevelle that went 71 mph in the 1/8th, I would set it on fire.
You didn't pay attention. You are wrong.
Then kepp runnin your 4000$ honda. The chevelles are fast sitting still as the saying goes. its a 45,000$ car either way
His reaction times were pretty slow.
Plus its geared for highway and long gears in tranny.. was made to drive on the highway at 55..
Dude, that translates to a 15 sec quarter mile. Good God, my Rav4 will run low 14s all day. I love that chevelle but damn. That slow for 12 mpg?
If the car is driven a lot, say 10,000 miles per year the savings are about $500 figuring gas at $2 per gallon. For a street car that gets driven the system will pay for itself. Of course I just would have put an LS in it with a turbo and gone farther, faster and cheaper.....
I'd be curious to see the MPG with a 4l80 trans. At least 20mpg I bet.
I would say that ET and 1/8th mile speed would dramatically decrease and increase with the proper tires for grip. Those radials were fine for the pre EFI run but you definitely need more grip post EFI install. I may just have to put this system on my 72 Grand Prix. Thanks guys!
My 66 Pontiac tempest ...be a dam good race ,with that Chevelle.406..750 dp..6 x heads..old school 70s torker,, single plain intake ...forged Pistons..solid flat cam....411 gear.on 275.drag radials....stock crank.rods.30 over bore...
see how many races you win smoking the tires like that.
Remember, this guy received the Holley EFI for free. So what do think was going to happen. Better everything.
Everyone I know who has installed one likes it. Including half a dozen mechanics who have all installed them on ford, chevy & dodge cars/trucks... No AMC's that I know of lol.
Dan Lyons we install them a lot at my job, I’ve only seen 2 out of like 15 so far run smooth at idle, drivability I have no problems but a lot of customers have issues that could be sorted with just a rebuild of the carb but my boss always sells people on efi and a lotta people don’t know anything and don’t wanna deal with it. Imo if it’s a daily I’d stick with a carb especially if yk what your doing. I had a 69 f250 drove it for over a year with a bad accelerator pump but it always fired even when 3f out just had to let it warm up for a min. Hard starts are also usually initial timing not carb issue, rarely a hard cold start a carb issue
Dan Lyons everyone I’ve ever heard of hates it so I’d say half are good and the other half are faulty
years ago I bought a Holly DI4 system,it produced great power,but wouldn't keep in tune over the long run.after many calls to Holley,parts change etc &along trip with calls & parts changes I pulled the junk off.and let it set for years,lately I contacted a person in LA who thought he could fix it with a new computer etc,he said the original system wasn't very good,but felt he could upgrade it,hope so or I will dump it in the junk pile,along with some HOLLEY QUALITY JUNK
Either that carb was way out of wack or they advanced the ignition timing with the fuel injection
Good comparison & anytime you can get a big block chevrolet to crowd 15 mpg - that's a real good thing
this ‘66 Chevelle is my Favorite 60s car! Yes, I know I’m a weirdo & prefer this type over the ‘69 and I prefer the “Malibu” lettering iver the “Super Sport” lettering on the quarter panels. I also prefer Roger Moore J Bond movies over S Connery’s films. I know. I’m a weirdo, but Damnit!, I love the ‘66 Malibu.
Judging by the rear quarter, they just repaved that track... LOL
Sure, this EFI kit does wonders. But the $2500 plus (install labor $$$) will put a bunch of gas into my 600 CFM Edelbrock 4-barrel carb, making 300 HP, in my 302 '70 Maverick. Yeah, sometimes it stinks, and sometimes I gotta warm it up. But it's ok with me. Old school: carb, Cherry Bombs, Anson Slots, and a welded 9-inch.
My buddy just did this on his Chevelle and the drivability and throttle response alone was worth it. Its costly but worth putting some money aside to do later imho.
just a word of advice. The car stalled because of the vent tubes on top of holley carb. when you stop suddenly fuel from the bowl will shoot out and into the carb causing stall. run a rubber hose from the two tubes and this will stop it.
Love 66 Chevells!
Had same issue would do it during hard cornering or braking. Have efi now prolblem gone
Ooh! Ahh! Gosh golly gee whiz! Did he say BILLET fuel pump? WTF? LOL // Jeeze, $1,260 in 2020. Ouch. But EFI is a game changer for performance, fuel efficiency, and comfort. I had a stock 302 in both a 1968 Ford Ranch Wagon (2bbl) and in the 1991 F-150 (EFI). The truck had what felt like 100 extra horsies and more torque, never once gave me trouble starting at 17F or 117F, and was otherwise invisible.
14 second 1/4 mile with 14 mpg? I'll take a new civic, thanks
Hahaha back to school Jen
As much as I agree the civic Si is a pretty stout car... put some sticky tires on the Chevelle and the civic is toast.
@7:55 install begins
I'm flabbergasted who uses a Rev limit on a big block 7200 8600 give me a break My files 65 I would purposely remedy 8600 at the drag strip Made all my friends motor up and put a ton of nos in their cars That was the only way they could accomplish a win
So why hasn't anyone made a 'real' EFI intake with individual injectors for a 'real' SEFI? Or have they? Seems simple to me. Megasquirt, Megajolt with a trigger wheel for distributorless ignition, done.
Well? I was excited about this conversion but was quickly disapointed with the video "How To Part"
After you lay all the parts on the table, I was expecting to see a Step by Step instructional video. Why you went into fast forward is beyond me, I really prefer the longer explaination of "How To" where you show Step by Step what you did. Is there any chance you could re-post the longer version showing the "Step by Step" process of "How To " Convert and install?
A properly sized and tuned carburetor will make more HP than any throttle body "injection". The word injection is a misnomer. It really isn''t fuel injection at all, more like an electronically controlled (feedback) carburetor. Great for fuel mileage and cold starts, but HP....no.
Is $2000+ parts (+ labor) worth it? That's up to you but there's no denying EFI beats carb when it comes to modern-day electronics vs. old-school mechanicals.
To make that much torque and that relatively little horsepower, this must be a very large displacement engine with a very mild cam.
Adds no power and creates about fifty different problems starting with fuel starvation then into adding heat to the fuel which ends up causing detonation. IMO nothing beats a carburetor.
old school plus carbs make more power in the high rpm range proven on the dyno
Thats why you love carbs.... you know nothing about fuel injection
Huh? Adds no power? 35rwhp and 50rwtq not to mention 9mph in the eighth and 3 tenths?
As long as the fuel pump(s) is properly sized no issues with vapor lock. Even 1000-3000rwhp+ can and do run efi on the street with no issues. Just run a small pump under vacuum and low manifold pressure, and a larger second or even third pump(s) under high manifold pressure. The secondary pumps are triggered by Hobbs switches at designated pressures. If Hobbs fail under high manifold pressure the majority of the time there isn't enough fuel for proper combustion to occur at max power(boost) and the engine goes so lean it doesn't hurt anything because there was no energy (fuel) present in that millisecond of a time frame to hurt anything.
@@martinsmallwood5581 ... It's refreshing to see a well informed person in the comments. 🏁🇺🇸
95% of these comments are from people who are butthurt they don't have a 396 Chevelle. YIKES BOYS, YIKES
It is a performance upgrade because efficiency is performance.
With my car, it's a sunny Sunday driver and all original. I like the carb life's little weirdness it has. However, a buddy put one on his T bucket 350 and he loves it. Especially being it sits most of the year and with a simple twist of the key it fires up right away, compared to cleaning the bowls out, dumping the tank for off season and putting it all together when on season comes. If I get a wrenching car, I'd do it
Rochester Quadrajet = poor man's EFI. Can't be a well-tuned q-jet
These systems are pretty awesome but like they said in the video, vacuum leaks are the devil. Any leaks at the header, manifold, efi or anywhere in the exhaust before or about 20 inches passed the o2 sensor will cause havok in the system.
Great article. As far as I last read (which is admittedly a number of years back) even the best EFI retrofit systems still made a few less HP than a properly tuned carbureted engine. I'm merely curious from a dollar for dollar standpoint how close the Chevelle could have come in terms of power and perhaps even mileage with more intensive tuning of the ignition and fuel systems to begin with.
That being said, besides the other advantages listed on the video I can really see a great improvement on plug life, especially at idle, and ease of starting every so often in Winter months.
Nicely done.
***** With a properly set up Carb the times would have been nearly identical. CFM is CFM
+Tory S The EFI will make more power, in most cases it wont be dramatically more though. The throttle body doesn't have the restriction and turbulence that carb jets induce at least with the current kits. Granted we are talking about a throttle body system, the it's not a huge leap really. Even if they were rated at the same CFM the throttle body would still hold an advantage because of the turbulence. MT just posted a more detailed dyno comparison using a LS motor and they had the carb jetted and couldn't match the EFI.
Wrong
Dan Henderson
Just shows the carb was way off and not set up correctly. This is a very poor comparison. Weld some bungs in your exhaust for O2 sensor. Set up a proper size carb as per A/F mixture then try this again. The carb will out perform
Something not right. 360hp and 500lb tq and only running 9.16
Carbs use gas when sitting still. I grew up on carburetor driven engines and I love fuel injection.
Turned your street tires into banana peels.
one problem when the emp hits you car will no longer work :-( but also you having access to a dino you can with ease tune the carb to perform exactly the same as the efi system and to get the same fuel MPG at your altitude just so you know ....i do like EFI it works but with my older duel tank ford truck not quite so cut and dry
Anyone who says carbed cars have trouble in the winter or aren’t driveable doesnt know how to tune their carb lmfao. Im 19 and daily a 69 impala 4 bbl carb 327 winters included. Not once in two years Ive had it has it failed to start or even require more than one turn of the key, even in 10 degree weather
I wish you should have shown us how each was step is done. Not very good video to us who are going to convert from carb to refi.
turn off the music, we don't need it. why does everyone think they have to have crappy music on the videos. Another thing what's
the distributor doing on the table, did you replace it, you didn't tell everything about this conversion. disapointing video
On a Hagerty video I saw that the full tach sweep will confuse the efi unit to flood the engine. How do you stop that? I have a 66 Gto with an aftermarket in the dash tach which does do a 8000 rpm sweep.
Those look like 15 inch rims , if they are not that's the first car that looks good with the larger rims .... i don't like the wagon wheel look of the 22 inch rims of today
GM rally wheels 15X8 came out in 1967, more rubber less rim.
There is nothing like a Chevy V-8. I have a Chevy V-8 powered Firebird. Check it out on my Channel.
Loosin' your hair, Davin?......why not lose those dopey trim rings on the Malibu as well?
Beautiful ride brother, 66 and 69 are my favorite Chevelle's 😎🤘
Awesome- I just bought a 66 chevelle with a 396 and this was something I was curious about. What did the system cost, and did you lose any of that old school muscle rumble or did the sound retain?
I want the same car, got the fever yesterday at a car show in Cumberland, RI in a grocery store parking lot. If that doesn't take the cake, how demeaning older guys with their very nice 396 Chevelles' at a food store lot, LOL! I have a garage for a future car I can not afford right now. Thing is I'm no mechanic by any stretch, don't know if I'm even capable of handling such an endeavor. I would need a PRO to install that electronic fuel injection system either way. But I can dream can't I? There are plenty of these cars out and about for sale I am finding. I get the sense owning one would become a nonstop hobby or fix it job. Any thoughts?
+dontswin it all depends on what is already done to the car, mine is bone stock except for the motor (it was originally a 327), so I'm going to be spending thousands of dollars and several hours installing disc brakes, modern suspension components, bucket seats and the efi system. I do have a father and a family friend that are very savvy with old Chevys so it won't be as much of a chore for me- but you can easily find one that doesn't need as much to be "modern", or just drive it stock! They're reliable enough, but some mechanical know how will have to be learned at some point in case something happens
+dontswin it's a blast though, I absolutely love it. My friend just finished restoring his 68 charger, a 10 year project! We're both 27 and can cruise the streets in style- you don't see many guys our age with these cars :)
Your right about your age group not having these sweet cars. As a matter of fact, young people are actually holding off buying cars these days. I also suppose it's a regional socio-economic thing too. The auto makers are having conniption fits about the lack of interest by the young people towards new autos. That's what the numbers tell. Myself, if you add 20 to your age that's me, lol. So when I was almost 8 these were BRAND NEW! I suppose I never stopped loving this particular car since my cousin had one way back then. He'd take me out a lot in it. It was all black, all stock(w/ a few mods) I'll never forget the sound. Sounded like a jet engine! I figure if I don't get one soon, I'll probably die without ever having fulfilled this one dream. So I really don't know. I do have a garage to keep it dry in for starters. But I am far from being a mechanic.
I bought a 396/360 in 1966. The 396/375 came out in late 1966. The guys that bought the 360 were out in the cold. If you have a 325hp you do not have the four bolt mains. If you have a 396/360 you have the high performance engine. IF you have the 396/375 you can tell it buy the intake manifold. It will look SILVER because it is ALUMINUM. NOW get a set of AIR BAGS for the REAR. The stock carboarator for a 396/360 does not put enought gas in the engine. YOU NEED a 780cc. If you have a 396/325 hp, that is not a high performance block. The 360 says hp on the BLOCK in the back. To make that car run you need a 4.10 rear. The rear will make the car go fast but it will cost you a lot in gas. My 396/360 came with a 331 rear. My best friend bought a 396/375 chevelle with a 4.10 rear and could not afford the gas. WE swapped rears and this made my car fast. There is a 396/375hp chevelle out they some where with my old rear in it.
it`s ok for a bolt on kit. But the sequental injection would be twice better than this one i guess.
Or you could just put in a Turbo V6 with 20mpg and a lot of butt hurt V8s to your name
I wish they had these back when I was daily driving a 69 Chevy. It drank gas like it was going out of style
If was just not red. Kinda ruined it for me No hate tho man love the chevelle got a 71 ss I’m putting a 65 396 in outta a corvette one year motor
Was looking to efi my sbc sprite
I have very little room in the engine compartment and under dash
Will this unit need much space?
You will never convince hard core carb guys that they need a dyno to get the hp results of an efi system consistently. They will never get the efficiency of efi.
He could add ladder bars for added traction also , at least back in my day
+Sam Nugent I had a set of ladder bars awhile back. the car would buck like a mule with them so I pulled them off and have a set of umi lowering brackets on the lower rear control arms.
