Set up for a smallblock race engine on pump gas 600hk

-
I FINALLY made 576, with 360 .040 over, and hand ported Edelbrocks done by my dyno guy. On his off time....over the whole damn winter.

If you check out the very long "missed on this combo" thread, go to the very end for the final results.
It was a long, expensive, and trying build. And I'm still having some "issues". I will say it is a fun motor on the street with 4:30's and a 4 speed, but I have some bugs to figure out this winter.

Someone prior mentioned it's all in the heads and boy is he right.
I honestly think if you grab some W2 stuff and have the heads done RIGHT, it'll be easy. So here's a good recipe:

4.040 bore with 4 inch crank
W2 heads that flow at least 300 by .600
11 to 1
Solid roller with around .650 lift and 265 duration @.050
Super Victor
HP950
Bang. You're there.

How long it will last is a whole other debate.

I just talked to Jack Barna
Motor is 360 Magnum 100 over, stock stroke, 775 gross lift roller cam. Compression is 11.95. 2.175 custom intake valves. Holley intake with 2 carbs. Has made 771 thus far.
Some stuff he is limited on because of the dyno challenge rules. Its called “ Race Engine Challenge” and is being held in Charlotte, NC on Oct 4th. Will be live streamed.
Mopar Muscle will soon have a feature on this build. Pretty cool stuff

I looked at the little posted on his web site but it doesn't say what block it is and the heads looks like edelbrocks. Unless he moved the valves a bit IDK how he ended up with a valve that big, and how he got enough port to feed that valve.

Hopefully I can figure out how to watch this because this isn't the engine masters deal. It's that other dude that I can't think of his name.

Its a 3/4 filled stock production 360 magnum block. It is bored 100 over( sonic checked good) so 4.100 bore. Eddie Victor heads, have 2.175 intake valves.
775 lift roller cam

Victor heads...ok that makes sense. Is that what he told you or did you find it on his web page? I'm interested in watching this for sure.

almost 12:1 compression on pump swill? I knew AL heads could do another point but that is crazy!

What he told me when i talked to him today. Been friends with his dad forever. He bought them cnc’ed, then did his magic. They go 380+.
How else would i know they have a custom 2.175 valve in them and have made 771. Wont find that anywhere.... lol

The aluminum heads have nothing to do with the ability to run that compression on pump gas. I've run 11.9:1 compression in my big block with 906 iron heads and .160" quench (if you can even call that quench). You just have to be smarter than your compression ratio.

Others on this forum can do the same thing.

I figured you were in his ear. If you don't mind asking him if you get the chance, see if he will tell you how he came up with the 2.175 number, as in was it all he could stuff in there or was it what he decided gave him the area he wanted. Kinda be nice to know what size exhaust valve he used, but I'm sure he isn't saying much, plus I'm sure he may not want his stuff all over the interweb.
 
He had to get the intakes custom made, so i assume with the bore what it is that was as large and intake valve as he could fit in.
Not sure on exhaust side what he used.
What puzzles me is the intake manifold. Holley only made that piece for W2, correct? Just wondering what is going on with that.... i forgot to ask him.
Not gonna bug him because he is running around and getting ready for the competition.
Gonna have him flow my local ported eddies, and see if more whittling on them will help the 418 they are going on. Also gonna play with my airgap, and let me know based on the bench if my 260/264 565/565 cam would benifit swapping to 1.6 intake and or exhaust rockers.
Have decided to just swap the top off my 360 onto the 418, instead of buying new heads and spending way more money for likely a couple or 3 tenths.
Plus he is gonna buy my 360 shortblock from me( which he built), will knock my bill down with him to not very much.
Wiring my car and painting engine bay already this offseason. Want to stay married..... lol
 
If you are not already married to those edelbrock heads(if they are the RPM version) i would recomend that you go for a better head,not that they are bad heads,they are not just a 600 horsepower head unless you want to push them hard.
Much more efficient to do with a better head,Some nicely ported W2s or some ported indy 360-1/-2 heads or Why not Edelbrocks Victor heads.
600Hp can be done with the stock replacement type heads but why would you unless you are already stuck with every other piece of suporting hardware needed to run them at that level?
 
I honestly think if you grab some W2 stuff and have the heads done RIGHT, it'll be easy. So here's a good recipe:

4.040 bore with 4 inch crank
W2 heads that flow at least 300 by .600

Super Victor

Hey... thats my motor !
I hope it goes 600 !
 
He already has Edelbrock heads that will easily go over 300 plus cfm with a little work. Edelbrock Victor heads are a very expensive upgrade. Get a little more flow out of them and maybe step up to a 1.6 rocker on the intake side

I must have missed the post where he says he already had those heads.
No they will not go 300+cfm with A LITLE work that takes alot of work and a boatload of knowledge.
Sure RPM heads can reach 600hp on a smallblock mopar,but its certainly not within their intended usage.
Do it with a better head and end up with a much happier engine,unless you just build a good 500Hp engine and then throw nitrous at it to get to 600.

No, that’s MY motor lol! Almost exactly!
11:1, solid roller .645 lift, 266/272 dur @ .050, Victor W2, 950 HP

I doubt that combo will back up 600 horse on a timeslip.
My W5 motor( when i had it) MIGHT have made a true 640, and it went 9.80’s at 135.car weighed 3350 with me in it on super stock springs. And taking 40 horse from that isnt gonna make a huge difference
If its 32-3300 pounds and isnt running WELL over 130 it aint making 600.
Not trying to bust balls, just a realist. People often toss numbers around that have zero realism at the track.
Mph at track is the truth serum
Rant over..... lol

That will all depend on whether we’re talking corrected hp numbers and such. If I take my time slip, plug it into the famous Wallace racing calculator and correct for the DA that day to sea level, my numbers come out to 600 hp. But that’s at sea level with that combination. Actual horsepower where I live? Not quite as much. But like you I don’t like to get wrapped around numbers so much as I do seeing real track data. That’s the real thing.

Yep, agree. That kinda talk is why i hate car shows lol..... guy walks by and says i used to have one of those with an 800 horse motor in it..... it ran 12’s..... lol
 
I may have missed this but are these 500 hp+ motors using a race block of just a standard la block?

I was always under the impression that you are asking for it when you are at 600 hp with a regular block.
 
That was a quote that I f*^# up....I was just commenting on how similar it was to my build. I have no clue what HP mine will turn out.
 
Stock block limit really depends on how you make the hp and how high you spin it. A turbo that “gently” feeds the power in can survive while a big stroke NA motor won’t. 550-600 in a stock block is not a trivial thing. The hardblock helps. What head you use is the limiting factor.
