Darth I'm way past the name or who did the heads aspect of things. In the right hands anythings possible. Also seems like you really don't have to go out and spend 4 to 5k. If I can save x amount being 2k and over and still be in the ball park as high end stuff. Win Win.

True. That's why I took that post down. Also that's why I had my own made to Not give Credit. And say that the aftermarket Ls3 heads aren't all that if you've got a standard factory set while saving Coin. 1st thing guy's say is go buy this and I understand the aftermarket is better ....but @ a Cost most times 2k or better. For what 20-30 hp. Everyone wants to be the top dog but not everyone has Top dog $. Funny thing is it's not gonna be some major loss at least not 2k+ worth. I'm not knocking just going by what I see.

You are the only one I've seen with aftermarket LS3 heads that impressed me. I get what your saying buy with only around $1k in work and good setup you can get 700+ very very reasonable.

I'm trying to find a company to make different runners for you guy's with other heads for the FAST intake besides the Ls3.... 3D printing 1st for cheap. Then work from there. Been to sick to follow thru.

The GMPP heads also come with useless springs, so you have to upgrade those as well. I believe I'm using PAC 1208x springs so that's going to add cost there to.
Aftermarket heads for the layman is more up front but the overall cost isn't a lot more than it initially appears to be. And the more efficient head will make a much nicer street engine. But as far as maximum hp in an all out racing environment the stock L92 castings will go a lonnng ways

I'm with both you guy's .....And really with not using GMPP Ls3 heads there's a lot more wanted. With stock heads and pistons you could say there is some problems with clearance.

Patron, I intend to get a couple beers in Mike Downs at PRI and propose that very thing. What would your minimum bore size request be?

I'm now at 4.030 Darin @ Reher had to weld the chambers for a 1.55 valve to fit with Ls7 heads. 2.20 still for the intake valve. Man I'm happy that You may get this done for the Ls guy's.....I really thank you...Truely! This gets done I'm done talking about heads. Would be able to say I've done all I can do with nothing left on the table about Ls heads.

I ran C45 on the last run and it made about 30 more hp than pump gas, but I didn't tune on it... probably another 10-20 in it with timing and more carb tuning... sounded like a whole different engine at rpm.
Pump gas is JUNK. Dirty junk.... *457 ci with 900 lift... I posted that so no ?*
The engine made 1025 hp at 8300 rpm, and 730 Tq and 6300 rpm. on 93 Shell. Average is huge, only 25 hp down at 7500, and over 660 Tq at 5000. 120 PSI oil pressure and break in oil. I'm pretty happy.
I ran it with the Tunnel Ram, and then a Single Dominator with a Cast intake. I can duplicate the power and curves with the Cast intake so that will stay on the engine, likely. Has better manners, and will fit in the car better. Unless he wants to just have a dual tunnel ram for show.
This engine is a little higher rpm than I usually build these pump gas engines.... quite a bit higher. Not sure what I think about that right now.
Valvetrain was spintron developed at 3V performance. Super stable, low spring pressure.
Hard for me to believe when I'm pouring that junk fuel into the cell that it was going to spit out those numbers and carry rpm like that at 460 inches but.... she's a good one!!! Lots of work in the heads and intake. I went after the cam a little differently than I typically do also and it packed the cylinder like a *****. If the engine was even a little fat like 12.5-ish, it was pissed off even up in rpm..... so it's really efficient... so to speak. It wants to be 13.4-13.6 AFR which is not uncommon but it will talk back to you if it's fat, 11.8:1 compression.
He should be able to drive it to the track, run 8's, and drive it home if he chooses.

Woke up from a buzz last night and a call was made around 7am from my sister...
Moms den went to a better place! I went and seen her and took care of what needed to be taken care of and left..Family and friends were talking.... I'm a loner. Looked around and she had a joke for me, left a whole bottle of Peach Vodka. This and forums like this is the only place I come to express myself. I generally don't talk or show feelings but here I can. Don't pay me no mind just had to let it out.

Thanks guy's!
How about 1025 on pump gas it had
4.125 Stroke, 9.325 Deck.
150-ish on the seat. Endurance type spring. .900 lift.
Here's another 1
Crazy part is the heads don't flow 400cfm the golden bench mark we all know of with the 2nd one being the 434SBC. This can give us or someone a idea of what's capable on pump gas with a Ls instead of the Ford being used on the 1st one.
