- CAN I MAKE MORE THAN 500 HP WITH AN ALL-MOTOR 5.3L? WILL HEADS, CAM AND INTAKE (HCI) MAKE 500 HP? IS AN L33 A GOOD MOTOR? HOW MUCH POWER CAN A JUNKYARD 5.3L MAKE? HOW WELL DO TFS 220 HEADS WORK? WHAT IS THE BEST CAM TO MAKE 500 HP? WHAT INTAKE SHOULD I RUN? SHOULD I RUN FLAT-TOP PISTONS? CAN I MILL MY HEADS? CHECK OUT THIS VIDEO WHERE I TOOK A HIGH-MILEAGE, JUNKYARD L33 (ALUMINUM) 5.3L AND TURNED IT INTO AN ALL-MOTOR TERROR! AFTER MAKING 480 HP WITH A BTR CAM AND FAST INTAKE, I DECIDED IT WAS TIME TO TOP THE 500-HP MARK! I THEN ADDED THE NECESSARY HEAD FLOW AND A MODIFIED INTAKE TO PUSH THE POWER BEYOND THE 500-HP MARK.

I hope all you whipper snappers appreciate how good you have it these days! Because when I was growing up with a dad who knew almost nothing about cars, having videos from world famous hotrodding legends like Richard (and others) at my fingertips would have already more than I could have imagined, but actually having a chance to ask questions and possibly get an answer from these legends should never be taken for granted!
legend is a stretch

Ain’t that the truth
Facts
Love your junkyard hp builds, would love to see you do a series on max hp you can make for like $500, $600, $700, $1000, $1500, etc. Any idiot can make big hp with big bucks, it takes a gentleman and a scholar like yourself, to make stupid amounts of power for stupid cheap, hah.
Lots of his vids show budget junkyard builds
Thats bananas to make 500+HP with such a small camshaft. Another testimony of making power on the Chevy LS.
If you’re will to buy the heads and get the porting
@@cedricwilson2055there are older vids of 400-600+ hp combinations NA
Sweet
Bananas until you price out the parts for yourself 😂, just get a big block chevy

That was awesome! Thank you for putting in the wrench time on all these videos.
I love how you are like a open book and don't mind taking time to share information 🤠
Great experimentation Richard. Congratulations on the results. Thanks for sharing. Still loving all your content from here in Australia.
Another question answered by your testing. Awesome channel, you save me a ton of money boss.
It's nice to see someone who loves their job
Man as always love the content i hope you do some more with 4.6 4v c head stuff.
If I had 480 Hp, I'd say that is a good day. I just read teh comments and answered my own question, if you started with a 6.2L would that larger displacement, make it easier to reach the 500 Hp ? Yes. RIchard says to start with 6 Liter.
Same...wouldnt waste time with a 5.3 unless it was stroked...just too tiny to throw money at otherwise.
Btdt Now a 383 with a good head, solid roller would be a riot...driveable 500+rwhp
Nice job great video!
You the man Richard.
I'd like to see some testing of the ported Fast vs a stock one. See if it's worth the extra cost to have someone do it or just get the off the shelf one from Wilson. Great video as always!
Its always worth it if done correctly. Some mods add more than others.
This is the kind of tests I like. Thanks.
Great numbers! I would run that in a street car all day!
hey richard if you have that holly crossram still laying around westech id love to see it get thrown on a 4.8L/5.3L just for funzies just to see how it runs too see if it can offset the low end power losses of throwing on a healthy sized cam
Nice combo
This is the good stuff NA all the way!
Just saw a couple of Impala SS’s in the junk yard about to go snatch the heads off one 🤫
Compression is key to this one doing better.
I’d love to see you build an aviation SBC. Something making similar power (maybe a little less for reliability), turbo normalization to maintain power at altitude and able to use 80% throttle constantly.
Reliability issues are usually with the PSRU.(propeller speed reduction unit). Harmonics management in that range costs big money.😢
big bang magnum! big bang magnum! big bang magnum! you're the best!
Right on
I just picked up a 58k mile L33. You’re giving me all kinds of ideas! 😂
they are good
Awesome
Great work! I love hearing the screaming V8. So many LS powered trucks pull campers. My LQ4 03 2500HD does, you know 7800lbs of 5th wheel slows it down some. Steady wind resistance and various grades keep it in “Work mode” at 2000-2400 rpm, 60-70+ mph. But the real torque at part throttle is at 2500 rpm and above, or 75 mph or better. So where does a guy hunt for moving the curve 4-500 rpm lower? Use the early iron head LQ4 camshaft, LM7 cam, or advance the stock 1721 GM cam, or? Thanks for your continuing content.
compression, displacement, long tube headers and boost all help power way down low
@@richardholdener1727
AND… of course a little bit of power building engine information from a legendary man does tend to help also!!! So, in other words… DO WHAT HE SAYS AND YOU’LL FIND PLENTY OF HAPPINESS WITHIN THAT LITTLE ENGINE THAT COULD!!! 💯💯💯
That would be great for a S10 LS swap 💪🏽
Pretty cool build making over 500 on a SBE. Loved the short circuit reference there #5. What was the total timing on that red hot cam for the?
29.3 deg
1.33 ft-lb/cube on a L33…… pretty good! Waaaaaaaa🎉
Thank you
You're welcome
Can you please do a build on the LS4 to see what it can do
But but but Scott Clark said your videos aren’t real life 😂. Thanks Richard. Keep doing what you do. We really do appreciate it!
Scott WHO??? 😂😂😂

@@gordocarbohe’s a dweeb from one of these internet tuning scams
This is nuts, no afm pistons or bottom end wow
Attempting to build my 45kmi sbe ls1 to 500whp all-motor this winter! BTR stg3 na cam, 102mm lsxr, TEA stage 2 heads, and some compression 🤞 Wish me luck!
No luck needed on the LS platform.
might need more cam-let me know and good luck
Lower the stroke and increase the bore, smaller stroke allows for faster pistons movement which leads to higher rpm therefore more power.
@GarciaQ60 Proven not to make a difference at these power levels w/this platform. Displacement is king & i want stock in this case 👍
@@2seep That gets expensive real fast!
How bout a 372 stroker kit with your best head's and a stroker cam
You should try some of 454chuy’s ported manifold and throttle body on some of these test.
Not impressed
we love richard holdener hiding in the basement running LS Horsepower experiments for us !
Is this L83 worth building stock block and heads but with carburetor or EFI ?
So what rear wheel horsepower will I achieve if I port 243 heads, red hot cam, paired with a stock gen 4 5.3 intake and throttle body? I have a LY5 motor
What good with the new 5.3+ motor
Ran into your page in suggestions and i like it 👌 i was curious i got a 06 sierra 5.3 , speed engineering headers,k&n intake stock 799 heads, stage 2 texas speed cam , stock injectors ,build diffrentrial 3.73 gears 3k stall witn rpm level 4 4l65e and how much hp you think its pushing?
need cam specs and what intake manifold
Is there a future for the L28ET series?
Richard, did you flow test these heads? Be interesting to see the flow numbers.
Also, inquiring minds want to know; Please test an LY6 with rec port heads and Truck Norris cam!
He said they are over 300
Hi great work brother but I have a question I was fortunate to come by a 2019 L83 5.3 all aluminum motor with the heads , could I make that a naturally aspirated running engine? It collapsed one lifter and scared up the bore just minor, so could I get away with honing it very lightly ? Ty for your time!
it already is a naturally aspirated engine
your the GOAT
I’d like to see a Gen 4 LY5
Can i do this to a 2004 silverado 4.8L...im sure i.can just looking fir another opinion. Wonderful videos by the way.😊
Yes you can! JUST LESS POWER
That's pretty impressive! Almost 100hp per liter just by swapping heads / cam / intake.
*laughs in Honda*
It is honestly wicked stout for how simple the combo is.
Yeah but 2x the power for likely less. Hondas are not cheap anymore. Not saying this is either but also laughs in torque.
@@btownballer27so true, Hondas were only cheaply built for like 10 years. Even then I'm pretty sure they were expensive everywhere outside of America, here in Australia you'd be paying twice the amount for a Honda engine that produces half the power, and a quarter of the torque.
@@joshthomas2536 a cam and valves/spring setup is expensive in a honda where in an LS you can shove a choppy cam in and an air filter and gain 50hp
So how would life/reliability be of the motor without doing other internals
Well Mr. Holdener. I am one of the tight LSA guyes. :)
2.04" intake valve in a 40.625 CID cylinder = 19.91 CID pr. Inch of valve diameter and calls for a LSA of about 109.5 LSA according to DVs 128 rule.
The point of course is getting adequate overlap for the job, right?
If we just assume the mild BTR cam has 217/237/114, the overlap is identical to a cam with 217/217/109 ;)
That is why it works so well. Its really is a 109 LSA cam, just with a lot of additional exhaust opening timing that confuses almost everybody.
I am on the DV train too. Typically, 109 and narrower is spot on for LS engines. Richard hasn't tested a single 109 (some ppl say the TN cam is actually 109) cam to my knowledge, but he has tested several 108s which should get all the torque available. But, all the 108s tested are only ~.550 lift which doesn't take full advantage of the flow of the rec port head. I'm ready for him to test 109 or narrower with at least .600 lift on a rec port ly6.
TN is 107.5
@@richardholdener1727 Don't want to be "that guy", but did you cam doctor or degree it? Or are you taking their word for it? They don't give full specs, not giving the correct specs wouldn't surprise me.
@@gearhead7896 More common than most people think...same with "custom" cams actually being a shelf piece
Cannot stand these cams without a grind in the PN, just stupid cartoonish names, stage xx etc. Tells me nothing
1HP/CID+ seems to be the modern manufacturer goals while 100HP/Liter is a standard for any aftermarket upgrades & modifications.
@richardholdener didja think to add E85 and some timing? Or possibly even race gas?
not needed
@@richardholdener1727 not needed to 500. BUUUUUT, maybe 550 is attainable with the right field and more timing?
@@ndemarco2013 Race fuel and more timing wont make him anywhere near 50hp.
Race gas is more to keep pinging away wont make power by just running it
I'd like to see the 219/227 .600" 112LSA on a 5.3l, 1500-6700 operating range! Very indecisive between that cam vs Truck Norris, looking for Torque numbers
that cam is bigger and will make less torque but possibly more peak hp-see the Best vs TN cam test
Why didn't you change the rockers? Maybe you could have got to 100hp/liter=530 hp...you were soooooo close! Facinating video ;).
There is more information packed into this 12 minute video than some people will ever try. And there is no shame in it. Don't cost yourself a bunch of money doing things you don't know how to do. Or you will end up on the channel Just Rolled In. Here is a thought. Do all of this, while keeping the variable cam timing system in place, and use basic tuner or whatever might be needed to make it run.
VVT becomes less of a gain (or even possible) with higher duration cams
@@richardholdener1727 What would be your guess with a power number once in teh car, all accessories exh etc hooked up?
Awesome, I like the tests. Trick flow heads are not bad 30 more HP. ...?... Definitely interesting. A question I keep thinking about is how can you maximize and keep a long steady Torque Curve. In the testing there was one cam that had a nice long Plateau of torque. Do you need rotating mass to increase torque?
rotating mass? as in heavy internals? big no
Yah I kind of knew that. That's why I keep wondering why the UK is so into lower the rotating mass. And in the US its only sort of popular. Cost is the obvious answer.
the US vs UK statement is not accurate
@@richardholdener1727 I definitely don't know for sure. I've only seen more crankshaft lightening in a lot of UK engines dance I first got interested in the Buick aluminum 8 cylinder that Rover took over. Of course racing the rotating assembly is the rods pistons as well as the crank. But I've seen the people in the UK going straight to the crank and cutting weight there. Everything from motorcycle, all 4, 6, 8 and even 12 cylinder engines. The North American prefer the big throaty big block engines. It's just my limited view. I appreciate your replies. Even though I know I might get under your skin sometimes. Thanks Richard.
@@barryhuddlestun3098 Ligthweiogh cranks on st engines are a complete waste of money .The same guys swear thier alum flywheel adds xxx power cause "it revs faster in N" haha
Have you ever done a test on electric vs factory water pump, could pair it with a test on underdriven crank pulleys as well. Might make a cool video if you havent done it
see the accessory video
Not worth it in costs, or gains (if any)
I'd love to see this with a turbo set up added to the final itteration of this motor
see the 5.3L big bang-similar
Soo what if you put the same setup on a ly6 6.0 I want to know what the outcome and And HP of that would be....
Are the rotating assemblies from a gen 3 iron block 5.3 the same as a gen 3 aluminum block rotating assembly?
yes
It would be nice if you could redo this test, but run it with all the accessories like it would be in a normal vehicle and if possible, mate up a 4l60e transmission and then run it to get some actual numbers of what a person could expect in their vehicle after spending all this money.
see the accessory test
Great job Dyno God! But can an all motor sbe 6.0 or 6.2 make 600 hp?
yes they can
Can i do this to a 4.8?
Would ported/worked over 799 heads make 500hp on that cam/intake combo?
It occurred to me while watching this that at 325 cubic inches, it's very close to the old 327(326.5 cubic inches). At 365 HP stock it is also close to the rating of some of those older HIPO 327's. Mind you it does it with much less compression and a milder cam. Would be interesting to see a comparison. Makes me yearn for an old F-body with a mild 5.3 and a 5 or 6 speed transmission. Very drivable I'm sure.
Cylinder head technology wasn't as good back then. So they had to use more cam & compression to make up for it. With modern cyl heads, the HIPO 327 would be a beast!
the stock (junkyard) 5.3L L33 made more than the 365-hp 327 Muscle car motor did
I'd be curious to know how reliable the strung out 327 of yesteryear would've been, in comparison. I know this 5.3 combo can easily be daily driven with AC etc.
@@STOK5OH 327s can go a few hundred thousand just keep it in good tune change oil etc. Same as any engine
Richard. I'm curious if you check piston to bore clearance on you junkyard LS engines? Reason I ask is that I'm building a junkyard 5.3 myself and my OCD told me to check this. I came up with .0055-.0060". Cylinder measures perfect at 3.780". Would that run or be an issue? Thanks.
what cam is that with? but yes, I have run those clearances (dynamic is it much more)
@@richardholdener1727 piston to bore clearance. Not piston to valve.
Nitrous 5.3 2.0?
Was really looking forward to the results of that last 5.3 nitrous test, but that didn't end too well, and seems to have been forgotten.
Another great video, Richard!
Question: this is exactly what I want to do with a '96 Impala SS LS swap I'm currently sourcing a motor for. I'd like the car to be 500hp all motor. I won't have a fancy ported and polished head though. So, considering I'm willing to take the motor fully apart for this build, could I get away with as cast trick flows and maybe an over bore, domed pistons, etc etc to get to the same 500? Or will it simply require / be most cost effective to do all the head work you've done here? Thank you, you're an excellent resource!!
If you've not sourced a motor yet buy a 6 litre and definitely 😂
The heads yielded 30 HP extra. Do you need the extra 30? Maybe a mild home port would yield 20+ without the expense of aftermarket heads....
Bigger bore (or 6.0L) would yield the 500 hp with as cast 220 heads
Wish you were my neighbor ! I'd like 500 Hp, via LS swap, for a 56 GM product.
Why not just build the LTx? You can make tons of power with one even stroke to a 409
What fuel did you use in these test? Running a Static Compression Ratio somewhere around 10.70-1 you need careful cylinder pressure management to run pump premium or were you using e85?
I’d say cool dyno water and aluminum block it should work
91
I have a 04 Chevy suburban with a 5.3 flex fuel motor with 340k on it. I've watched a few of your videos and I am trying to figure out what would be a low budget 500hp build for my motor. I'm going to slowly buy the parts for it. But I'm not sure what to get. Thanks again for the videos.
the only low budget 500-hp 5.3l is boost
What tuning if any is needed for the red hot cam and intake? Is the stock ecu enough to compensate or?
requires tuning
@@richardholdener1727 Thanks!!
@richardholdener1727 how much are the heads milled? Im doing the redhot cam but on a gen 3 5.3 with cncd 862s. Id like to mill .030 off and get compression up.
.030
Just a question y didn't you try a roller rocker with the 799 maby that would get you what you need to get that 500 on a budget for say doesn't have to be a over sized ither because along with a bigger cam the less friction for say the better so going to a roller set up if my thinking on this is right could get you a Lil more rpm out of it and where you using stock valve springs or what
And also could have tried the trailblazer ss intake as well
roller rockers won't add much on a cam that already has sufficient lift. The stock rockers (already roller) are lighter and will run more rpm than full rollers (much heavier).
Would this be a good combination if you were to do a supercharger or turbo down the road?
yes
Probably a silly question but what would get better mpgs? A stock 5.3 making 500hp with a turbo or a 5.3 making 500 all motor? Thanks for the great videos Rich!
turbo and mild cam
What other heads would work to make this power? Is there any heads that I could just buy and bolt on without having to get them Ported?
yes-the 220 tfs as cast heads or you can buy and bolt on many stock or after market heads that are already ported
Richard, a little bit of speculation here... a similar junkyard LQ4 "should make around 40 more than the stock L33 - correct? If so, would it be safe to say that the top end and cam from the L33 should make around 40 more in modified form too? That would make a 550-ish flywheel setup pretty easy with a junkyard shortblock and good top end parts.
The math there checks out IMO, definitely a fantastic cylinder head.
A 230/240 cam with that head would maybe make close to 600 but piston valve clearance would have to be looked at because of the mill job. I can attest to 600+ being doable with an aftermarket 11:1 piston, ported LS3 head and 240/250 cam.
Keep in mind the way Richard test his engines is without accessories. So whatever number you see deduct about 25 hp for real world numbers.
@@sstevocamaro 25? I think it closer to 50at the flywheel when he added a regular water pump, accessories, mufflers, etc. I'd have to go dig that video up. The engine dyno to chassis video they lost 100 in a drift car with a manual transmission.
I definitely don't get hung up on peak numbers. I look at tests like this more for what percentage did it pick up stock vs. modified.
@@bluecollarhotrods9781 Maybe -50hp total with a fan hub attached and activated
@@sstevocamaro That particular test I'm referencing was a stock 5.3L. Richard added: clutch fan, conventional water pump, alternator and power steering pump, air box, longer sections of pipe with mufflers. It was an excellent illustration of what robs power and how much. The other notable one was the effect of temperatures. He runs most of the tests with optimal oil and coolant temperatures.
I have a built NA L33. I just moved from the Dorman LS2 intake to the MSD atomic and lost 37whp and 17wtq. In your experience, why would that be? Power is down starting at 2400 rpm, and the loss grows as it runs up to the 7200 limiter.
11.3:1 comp on 91 gas
AFR 225 cnc heads
TSP Torquer V4 cam
Previously made 399/364 before the intake manifold change.
The Dorman LS2 makes the same as a TBSS-the MSD makes more in every one of our tests
Let me know if it’s still available. I’m up 505 in Arbuckle.
at what power would you decide to go forged pistons and rods? i’m wanting to go similar set up with a little boost. should i tear into the bottom end?
you don't need forged-just ring gap for boost
Also what injectors/ rails are you using? Thanks in advance!
ls3 rails
I am looking to do something similar and I don’t know very much. I would be willing to mess around with new piston, what would that change and how should I go about it?
what would I change to do what?
Were you using stock length pushrods when you ran the L33 and stock 799 with the red hot cam?
7.425
@@richardholdener1727 I appreciate the answer!
What about tsp cams? With the exact same set up what difference what it make on power?

Hey Richard how about the amr500 on a 1941 ford flat head four????????
any na motor that makes less than 100 hp
Tunning videos??
Richard, I just found your channel, and I hope you get this. I've got an 07 four-wheel drive, Yukon. I bought it minus the engine. We took a cast iron 5.3 block put a high volume oil pump, one set of top, and one set of side oiler lifters. So there's one tip and one side oiler lifters per cylinder, just to give it a good oil bath. We then added a set of cathedral port 706 aluminum heads, and a 6.0 Corvette cam. We also built it as a DOD delete. The majority of the parts came from Summit. My question is. Did I increase my performance by any real amount? Being as I never knew what it was like before the original engine came out of it. I'm thinking of doing the intake and if I went with the cam you used in this video. What kind of horse power numbers could I achieve? I'm trying to get the best horse power and torque, but try to stay within my configuration. I have Champaign dreams, but live on a baloney budget. Lol I hope that this reaches you. Thank you for all of your time and advice in advance. God Bless.
side oiler and top oiler?
Lifters...what are you talking about?
So does an engine dyno compensate for the loss you would see on a dyno to the wheels ? Just curious since you lose a little bit through the trans and drivetrain components, so would that 500 hp to the wheels realistically be like 400?
wheel hp would be less than flywheel hp
No it doesnt
Ok, im sold...how much is all this going to cost me?
Do you think the stock 862 heads will be good with the red hot cam?
yes-it will just makes less than with ported heads
@@richardholdener1727do you think it would still run pretty strong with those heads? Looking at boost for later but doing a budget build with it
Could this be done on a iron block? And what injectors are you using ?! Thanks rich
yes and we ran 80s
I dont want stock bottom end tho seems sketchy
Johnny 5 is alive!
How much more would it gain if you changed the piston and ring thickness? You would still maintain reliability but squeeze a bit more.
I’d just like to see how much more you could get reducing as much friction as possible.
Hot Rod Network did a RUclips video where they gain ~8hp from going to 5/64" to 1/16" on a very healthy SBC (close or over 500hp). So, probably less than 8hp. I haven't watched the video in a while but, those numbers should be very close. ruclips.net/video/-29IWc-zrv8/видео.html
I know pricing on parts can change, but could you do a build vs value video? I am torn between 5.3 and 6.0 with making hp vs cost.
6.0 all day
