You could be right, Hio. He always did say his tune was pig rich. Regardless, how much Hp would that be going through a manual gearbox? Maybe 415-420Hp. That does sound to bad for a cam-only/bolt-on/stalled LS2 to me?
Am I off on this?

One of my friends used to have a cam/fbo LS2 goat, he said he was around 480 to the wheels through a manual on 91. That seems to jive with other healthy examples of cam only LS2's I've read about.

Mach, how familiar are you with the Raleigh area?

cam only ls2's has made 500whp.

i would expect a even ok cam only ls2 to get near what i made with a stock cam even through a auto. Realistically a ls2 isn't anything but a lager slightly milder cammed ls6. He shoulda made his 396 with bolt ons or more. It didn't need a cam to make that. It needed solid thought out bolt ons.

480WHP cam only? So heads and cam is over 500whp? That seems pretty high I would think.

BTW, I am familiar with the Raleigh area. I live about 1/2 hour southeast of their in the tobacco fields. lol

480 Cam only? Id assume those 243's where ported. Also what cam because HC setups on a LS2 usually dyno just under 500hp. Now doing a super light twin disc, EWP , Vaccum pump and E85 might get the car into the 530ish range to the wheels.

Wow...I did not know that cam only can be that stout. Hearing that, I guess his numbers were pretty low then. As stated, he now has a Mamo h/c package now but I do not think he is still near 500whp. I'll check with him to see what power he is making now with that new setup. I am curious.

With a stalled auto he should Dyno high 470s low 480s on a dynojet mustang Dyno might be a heartbreaker but the track will tell the true tale a little weight reduction and it should be a bottom 11s car no problem.

i made 451 with stock headsn stock cam, less bore and .4 less compression than a ls2. A ls2 is nasty when right. They're just begging for a cam and intake. The dcr is pretty high on them and that makes the oem tune soft. A cam brings it all into check better.

Darth made 540whp with a well thought out h/c ls1. No reason a well thought out h/c ls2 shouldn't make significantly more really.

Just went to the local 1/8 mile track ( Wayne County Speedway) with him 3 weeks ago after a long time of getting a trans built that did not take a crap. With his new Mamo setup, he ran a best of 7.7x @ 92mph. It was a cold damp day. This is stock weight with no weight reduction. Built rear with a 3.7X gear. (not sure of the exact ratio). I think it has more in it though

Good/bad?

True and Darths build was extremely well thought out build, But there is a reason PatG did the 500hp recipe build because that is the normal expectation for a HC LS2. I agree a lightweight clutch vacuum pump turn one ps pump e85 EWP would get you well over 500hp.

Correct, he spent a considerable amount of timing telling people stock heads, it later came out they were ported. Is still correct to call that "cam only"? I'm not really sure. Definitely not e85 though. He had a slew of drivetrain mods, but I don't know the full measure of that. The 470ish to 500ish hp numbers seems to be what I remember the healthier cam only claims to be, but I'm no LS expert. I know it performed like a near 500 hp car when I ran him in my old 2.8 pulley eaton setup.

seems about right for the weight and conditions, now some weight reduction and that thing will shine.

That's bad....like real bad for h/c bolt on car. Puts him at a low 12 probably.

Ported 243's count as heads and can flow really well if done right judging by his numbers they where definitely CNC'd at some point. 470 cam only on a LS2 would be the high end average most of em have heavy LS7 clutch setups that eat a ton of power.

Its full weight likely over 3700 pounds all things considered with the mentioned conditions that's not bad.

Ah, ok. My bad then.

Mach, how are the emissions tests in or around the City? My wife and I are considering Raleigh as a possible moving destination next year.
