I'm sorry it's not to your expectations.

IDK. Maybe Greg's heads woulda done 690 with compression. but you can't figure every build in that territory. It's a record for a reason. And that reason is -- nobody else has done that good ever. No I think with factory LS7 heads, he would have been lucky to get 650-660.

I agree on TB size. Imagine a 4.5" holesaw, some sheet aluminum, some epoxy, and a 112mm TB...

B.....it's your build ....wink,wink ...it should make only u happy. ° cam lift my friend and head/runner area + more compression is the only difference in mines and yours. ✓°^

I luv your spirit B.

Darth 690 was there with GG heads and there's no Doubt about it. It's Fact!
add the same compression with the same splash of race fuel. 690+ fact. Darin heads would want even more Lift and TB because of the given runner size better said Minimum CSA. So yes Darin's heads could and can make More. Don't believe me ask John. 302cc was Darin's runner size vs I think 270 or 280' for GG heads...1 has a CSA of around 3.2 while the other may have a CSA of 3.0.


One wants more lift and runner area...for more
Next person I need to talk to again is George Bryce...nhra guy....he sees heads in a different light.... Kinda like ER...biggest valve in that'll fit with some ***** for CSA. There's a reason why all newer GM heads have larger ports... fill the cylinder....

11.7 vs 12.7 with a splash of race gas can't get me 20 hp to the rear? Think I'm close on facts for the compression. Moving 2 fast 2 ✓ but you read between the lines well enough to no.

Walk towards the light Darth.....we want u

OK, so here's my question -- why didn't the OP then keep the GG heads, bump compression, and add race gas??? I mean, I hear you, Greg's heads were smaller runners, but also look at this -- Darin added 30cc runner volume and nearly 10% CSA AND a compression bump, and he gained 18 HP. You get to a certain point and it's dminishing returns.
I think it could and should, but then I think -- why didn't the guy who built the car try race gas and hit 710-720? Seems like an easy 10-20 hp. Or why didn't he try that before spending what I'm guessing is minimum 6K on Darin's heads? Tank full of race gas be cheaper. unless he did try it, didn't see the gains, and never posted about it. That's my guess anyway.
LOL, this one made me smile...

Thing is John seen those head listed here more than likely as I did and bought them .. ...Done by Darin for a EMC build...listing of the sale is Still here with with most specs..yeah it's still listed... research King that I am. John says in the thread he thought compression was the same but found out it had less cc for the added compression... Ask John ..yet sure 99.9 %..

​​​​​Yo... B? I've been around and had a similar thought as u. 408 hyd roller 4500 and 11.5 compression. Life was simpler went I didn't know. If known u ask 4 more

Because at this point there’s no “easy 10-20 hp”

Smoke, a half point of compression isn’t 20hp.

An engine isn’t a stack of “10-20 hp” that you just endlessly add up or we’d all have 1200hp NA motors.

Smokey B

If u got it $ and see it ...your not making that purchase to have GG heads and Darin Morgan heads ?

2 names in which .. .....GG says Dyno heads and such don't win championships. This was on GG CID heads vs F710's

Darin's perspective
I would rather work in the background, jump out and kick there asses. Lol

I dont care if you respect my opinion or not SMOKEY, but you will read it. I know in your mind i ve done nothing n know nothing. But either have you. You are a bully. Your more like the Farmers Almanac than you are a Weather Man. FACT! In this sport, we put up or shut up. Heres the deal, this is one of a few hobbies where theres more than one way to skin a cat. Theres also more than one reason to do something. 98% of what you preach on here is pure Racecar bs. Nothing more. I dont see you out playing with the big boys! Instead your here in the kiddie pool pretending to show off. Its bs, and people gettn tired of it. You speak in ebonix n talk out your butt. You cloud up perfectly good threads with regurgitated gibberish. Most of these cars are STREET CARS. Your hypothetical simulator runs off of Wallace racing calculations as fuel. I try to stay out of certain threads, including yours, but somehow like a car wreck, we get sucked into watching it. Get off this site! Its beneath you, your time, n your knowledge. Engine builders, including mine, dont come on here bcuz of guys like YOU, FACT! Nobody wants to email back n forth n be on the phone like little school girls talkn n sharing secrets they workd hard to achieve...especially with people who dont spend any money with them! FACT!

Spanks a full point on compression and just 93 vs a added blend Is worth something Brother... And I know you know some tricks. Hell easy Math 93 octane 11.7 compression Vs 100 octane 12.7 compression motor ... yes something's there.

Smokey B

I know and like both guys. But being Honest is paramount. If your car made 680 you milled the heads and added what was added ....wtf would u expect. Honestly? 684rwhp GTFO. Like e85 vs pump

Sorry first time I read your post I thought it was a half point not full point. Still, a full point you’re not getting 20hp.

Take it to the extreme and you’ll see my point.

11.7->12.7 680->700
12.7->13.7 700->720
13.7->14.7 700->740
14.7->16:1 sprint car motor on meth... 770?

More compression is more better, but it’s not going to gain that much just by changing compression.

Smokey B

rkupon1... I know how to control my reactions ....go ask John B? Yeah I'm that dude chump with a weak Spirit cause u Scared to go to the or a person who does what your thinking. Yet will get on with BS...look in the mirror. Boo!

Look, what would we do without Smoke? There’s barely any content on this site anymore. If anything he brings examples from the world outside stage 3 cam kits from the latest hot name on the Internet. At least he keeps threads rolling lol.

I think some people need to learn to scroll past if they don’t agree or are tired of the broken record of putting race cams and intakes on street engines lol

Smokey B

If I'm far from the truth a friend will generally come on and correct me...wink wink...

Made me think of this one:

Smokey B

I just want u guy's to think....and not what the normal nay Sayers think or do. I'm moving around but willing to bet I can find a decent comparison of the difference in a full point of compression and higher octane fuel. Answer honestly how much would you expect ..if 3 rwhp is seen. I'm jumping off the bridge to day. 683rwhp kill myself✓


Talking to the tuner or 94z28..you better run this some B rich or something...I'm not accepting that...
