COngrats to ***** Highest dynoing local LS1

[HybridSS]

stock bottom end, 346 cubes, rather large cam ;) and some halfway decent heads:D tuned by Mr. Formato.

478 rwhp and 414 rwtq naturally aspirated no nitrous, no blower, pump gas freindly 10.7 to 1 compression.
Still has some tuning issues and a few tricks to squeeze a bit more out of it. 500 rwhp NA from 346 cubes is within reach.

Thats one stout combo.:D

[Country Boy]

NICE! Whats some specs on the setup? My big cam,, stage 2 setup only hade 425 hp and not even 400 TQ :(

[DaTruth]

Thats insane.. Still 77rwhp/106rwtq less than me;)

[onesweetZ06]

He's all smiles, Thanks too many. Dan for letting me tie up his dyno for half the dyno day.. Al for a great deal on some killer heads..Brandon for his sweat and tears over porting them and Jeremy for getting her tuned...Yeah I think there is more in her

But.... its still 42 less cubes ;) j/k

Sweet setup James! The stock motor seems to make alot of power, especially over a forged setup.

Then I should be only making 42rwhp more;)

Congrats James!! Your dynograph is sick..

[HybridSS]

7300 rpm peak power:crack: still hyd cam car:beer:

[HybridSS]

Brandon heads strikes again. This head is actually not ideal. But it still works well enough...obviously. I am going to go out on a limb and say this car may see 500 rwhp NA 346 stock bottom with a few more tweaks.

Congrats James!! Your dynograph is sick.. Thanks Vince...Are you sure about that 42hp? Actually going by your #'s 546 RWHP = 1.33 hp per cubic inch the lil 346 is 478 rwhp at 1.38 hp per cubic inch:lol:

[Scott]

Wait GM guys arguing about cubic inches ? :lol: That a hoot considering past discussions.

You ricer:lol:

Correction though...Vince made more than 546

[gator]

vince made 555 rwhp i believe. and we dont want to talk about peak power and area under the curve! big cubes = broad powerband. could be a great race on paper! ;)

onesweet, your car sounds good. bit loud lol, but good.

[HybridSS]

yeah...it starts to SING abover 5000 rpm.

[gator]

N/A sucks. :)

What's the intake port volume on those heads, with the added epoxy?

[HybridSS]

237 cc

[NXz28]

Are those ls6 heads? Any flow numbers?

[HybridSS]

They are 6.0 heads and they flow 338 @ .600 lift

but the midlift is crazy. at .400 lift they already flow 285 cfm...at .500 they are 320 cfm


Keep in mind though these head were setup with a 4.060 bore. They are now on a 3.90 bore. Thats why they are not ideal. That and a few other minor things. But they are obviously still effective.

[DaTruth]

The heads are obviously effective. We got a chance to see them in action last night;)

[351coupe]

[qitstrn]

Nice numbers.

03's = :bbb:

Those things are a pain. And my turn around time is just short of eternity. (ask Sam!!)

I think once I'm set up again to start doing work (just moved), I'm going to stick to the high end custom stuff (read $$$$) like Al's....er James' heads. ;) But we'll see.

[Jakethesnake]

well let me know man!!

Jake

[JFormato]

There may be some more in there, but nonetheless great power.
Jeremy

[Mike01Z]

Thats really impressive numbers out of a 347, I honestly did not think it was possible, I really thought all the guys on ls1tech were liars lol and yet we got a ringer down here in FL locally!!! Grats OneSweetz06 on the stoutest head/cam package around !

[gator]

run race gas, open header, no belt, and turn that timing up and lean it out! atleast that is what the other shops do with these big cam and head combos.

[TAWS6]

impressive numbers
