Steve's Stunning '68 Chevelle Malibu is down on power? Not as punchy as it should be?

- A few short months back many of you will hopefully have seen us tackle a few upgrades and improvements on Steve's stunning factory show room style build with a 1968 Chevelle Malibu. Well after all that, including a new 3.73 rear end gear with posi traction reached out with a worry that it just didn't feel... much better than it did. Gears should have really woken this car up and brought out the attitude of that small block Chevy under the hood.
So she's back in the shop and ready to go under the knife for a little "minor" surgery, a balljoint needs replaced, some carb fettling, possibly a bad or unbalanced tire, and ... whatever the heck is wrong on why the "butt dyno" seems to be telling us it's down on power.
As you'll no doubt notice this video seems to be a little longer than you would expect for a little "quick fixing" and that's because, just like for a lot of the rest of you, sometimes (often) projects go sideways. But, you roll with the punches and get done what needs to get done!
Huge thanks as always to all our subscribers, followers, fans, and customers who have made our business successful and gotten our channel to where it is today. Special thanks to the SRC / Street Racing Channel / SRC Garage / Old Man's Garage / Junkyard Digs folks for showing such amazing support for us over the past several months. Without all of you we wouldn't be anywhere near where we are today. We hope you enjoy this one!
Sometimes even those "little jobs" end up becoming far more than expected. We aren't the only ones this happens to, right?
Rich you treat these cars as if they were your own. I think that 68 is a nice car. Glad you got it fixed. Love your work!
Austin /Rich - Thanks for another badass video of real world mechanics, not OBD laptop readers! Let me know when you come to Florida. I'll buy y'all a beer!
Thank you.........
Had a few cars that just wouldn’t run right. They had open air filters that the filter paper got damp and sealed close. Amazing what a new filter did.
Is Steve holding your first child hostage until he see what you have done to his car !! 🤣 Can't really blame him. It's beautiful.
I love all your Pro tips Rich!!
Good evening Austin, as always awesome video, it got to be tough when they garage calls to tell i we got to pull the transmission when u brought it in for maintenance, but Rich did a great job of getting this beautiful Chevy back on the road!😉
It's certainly not a call any of us want to make BUT that's a big portion of why we have built the reputation for honesty that we have. Also these videos go a long way as well, our customers can actually SEE the work that goes into their build/repair. Fortunately though this was a relatively major surgery in and out in a couple days and he's back on the road for the long holiday weekend.
We appreciate your watch and support as always Charles!
Another Great Video Lucore Guys
The Old Man always breaks his stuff in nice and easy !!! 😂
I wish I could go on the test drive with you!!
Speaking of breaking rear end gears, have ya seen Bill lately? (😂 couldn't resist!)
Saw him at the track the other day when we took the Pontiac out 😀 if he breaks that Ford 9" heaven help him!
@@LucoreAuto I hear ya! 😂
I really love that Chevelle Malibu whatever it is. And it's a standard? Yeah, I love it
Yes Sir, very healthy small block under the hood, 4 speed Muncy manual transmission, and a 3.73 rear gear with posi out back.
@@LucoreAuto for me,that's a perfect combo
Question: when working on a customers “stunning “ vehicle wouldn’t it be wise to use a fender cover so as no to even remotely possibly scratch the fender? Beautiful car and great content explaining each process!! Enjoy the channel.
Thanks Rich for taking me down memory lane with the spark plug cleaner I had one many years ago I have to say I haven't seen anybody use one . As usual you do awesome work keep up awesome content and as always be safe 👍
P.s. my first car was a 68 chevelle 396 ss
The M21 Muncie in my '68 El Camino doesn't have a drain plug either. The engine had 11:1 compression and I used AC44 sparkplugs.
My very first car was a 1968 Chevelle Malibu! Pulled it out of a backyard for $600..
Good video by the way,
Thank you, we appreciate it!
Another great video, Rich! Really clean/sweet '68!!
You mentioned in the beginning about a possible muffler seam leak.
Find anything or is that in the next video?
Respect from Iowa!
That will actually be addressed on his next visit, the seam welds on one of the mufflers are blown out in about 5 different places and it's not really something we can "repair". The metal is super thin and super contaminated with soot so just going to put a new pair on there in the semi near future.
Glad you enjoyed it, this was SUPPOSED to be a quick little in and out video but... sometimes plans change!
@@LucoreAuto Trust me...I'm an early 70s baby. I grew up around cars/trucks long before being computerized. Used to be a mechanic. Got burnt out in 1999. Yeah. No fixin that. New mufflers haha
I heard the Squeal in the Clutch when it pulled out! Strange it went away?
luk clutch kits are nice.
the choke rod dashpot is notorious for losing it's spring power causing it to run rich when cold .
This clutch kit is for SURE a good upgrade and totally changed the characteristics of the car. Gotta take it easy for a little bit but can already tell it is LOADS better. Good point out on the choke rod too!
A lot of those Muncie 4 speeds didn’t have a drain plug, I have a M20 that doesn’t.
i really enjoy the channel
Thanks Bronson we appreciate that. Just a real shop out here sharing real wrenching experiences! 😀
Rich heard you talking about the oil pressure on your Buick the 455 is known for bad oiling to the cam bearings if it has been over reved the cam bearings can be scored and even spun there are a couple fixes for this one is on the back of the block there are 2 quarter inch plugs that go into the lifter gallery on each side 2 quarter inch elbows and a piece of quarter inch steal line will provide better oiling to the cam also by cutting a groove into the front cam bearing with a cutoff wheel allows for better oil flow
I don’t normally critique others videos and not trying to be an A-hole. But Jegs sells fender covers with magnetic strip on the top side that work very well.
I swear every “ little job “ I do on my own stuff turns into a fiasco … my 72 Blazer , worrying harness is garbage so before I drop in my Afr headed 355 I need to take care of that , in turn I need to replace all my body mount bushings as I found quite a few rotted out , and I might as well utilize my life and take the body clean off the frame and clean and paint it right ? … I want it back on the road though 🤣
I hate those plastic alignment tools. Clutch disc always has to go up a little bit to get the trans in
😎
i usually put some light grease on clutch splines and pilot and i'm sure you did and didn't show it, another good job rich
Love your thoroughness great content. Quick question what are the top three reasons a dipstick in a Chevy 350 will not reseat?
I'm so glad to see you put a microfiber cloth over the Chrome air cleaner fender covers please no offense shirt button scratch and press into the paint and at a car show they're all so close to perfect that any little thing loses points if he's showing it
It looks like that malibu, is the same color as, the old man's
It's a very light green body with an I guess Ivory / Eggshell roof. Pretty nice and unique looking car unfortunately the paint color doesn't translate well on camera
What heads does the engine have? Trick Flow DHC175’s?
If so you need to use 3/4” reach gasketed plugs. Like NGK BKR5E, or an ac delco 5 heat range equivalent.
And they do have a heat crossover to warm the choke. As long as he didn’t cover it with the intake gasket.
Also, timing should be 38 at full advance with vacuum advance disconnected. And not more than 52 with vacuum advance connected. Should actually limit it to 46, maybe 48. If he does have modern heads.
He doesn't need your incorrect advice. Idiot.
So after you tighten that bolt or nut down, I heard you go click. It made me laugh, cuz apparently you watched the other guy that does the same thing with the car rebuilder
It's not very a hard to convert that hot air choke to electric.
It is if you're getting judged for points.
Factory two tone car ?
Bias ply tires. The belts are moving or he needs to have rubber ground down even. The owner should buy the new Firestone Wide Ovals in the radial version.
Early Muncie transmissions did not come with a drain plug. You need to drill and tap a hole. I always have my flywheel resurfaced and balanced. Last time my engine was rebuilt the flywheel and pressure plate were balanced together along with the steel crank. I have no vibrations from 0-80+ mph. Should use the bronze pilot bushing that gets lubed by itself. Yes I also use a Luk clutch BUT with a GM throwout bearing b/c the one in the Luk kit is garbage. I alao use an old input shaft to line up the clutch disc instead of the junk plastic sloppy tool.
And yes I also had a problem getting the input shaft splines to slide into the clutch disc splines. Maybe I had a burr. I did add a bit of lube on the splines too. When I was in my 20’s, I stabbed it in the first try, but the clutch was not new, I just replaced the M20 gears with M22 Rock Crusher gears. I love the whine but not the close ratio of the M21/M22 compared to the wide ratio M20.
My input shaft finally went in after several tries rotating the tail shaft and praying. I usually only use 2 guide bolts with the heads cut off on the top 2 tranny mount holes. This last time I used 3 to be really straight going in. Do Not bring in the trans that last 1/4” like some people do with the mounting bolts or you may break off a mounting ear off the tranny!
Oh ya and I did try the trick of pressing the clutch pedal down BUT it just misaligned the clutch disc so I had to remove the pressure plate and do the alignment again. If you try this I think it would work if you had one person press down on the clutch pedal and the other person wiggling the tranny home onto the bell housing.
He should be using R45TS.
That weird noise you heard when you first started it up with the new clutch kit was the throwout bearing lining up on it’s ramp when it stopped turning. Manufacturers along with GM throwout bearings have a ramp. This single ramp stops the throwout bearing from spinning all the time thus increasing the mileage on a throwout bearing.
If he has a divorce choke on that car and it’s not fully opening the choke flap then someone installed the wrong intake gaskets. You can get 3 different kinds. One that closes the heat passage hole that won’t warm up the engine fast, one with a small hole cutout and one with a large hole cutout.
So if he has a mild winter wherever you guys are, you can just keep the choke flap open all the time with a mini nut/bolt.
Oh come on, there's not much difference between break-in and broken!
Lol depends who you ask 😉
@@LucoreAuto lol, guy brings be a 1970 nova with a 327 in it. Says motor is fresh, set on a stand for 10 years. I ask him if they removed the oil pan to relube the cam? Customer says no. I ask did they break in the cam? Customer says how you do that, it's already new/10 years old. Needless to say cam is wiped, and has a slight knock.
Why is there so much background noisr????
Working shop???
I hope the owner is in his 80’s and can’t do basic maintenance on old cars.
