riding on the hwy and notice a mustang with hids behind me, I am running about 78mph and he gets out from behind me and goes about 80...i wasn't going to mess with him untill I saw the gauges on his apillar...i am thinking this could be a good run and the saleen was nice as hell...white with white wheels and slammed just right. I dropped back to 4th and at first he did not seem interested so now I am a car ahead..then all of a sudden he hits it and so do I . I was ahead by half a car when we started so it wasn't a straight up race but I put 3 to 4 cars on him...hehe the guy was real cool and gave me a thumbs up...dont know if it was blown or all motor I am at 491rwhp/428ft

Depends on how long it took you to put those 3-4 cars on him... if you went from 80-100mph, it was probably N/A. If you went up to 120mph+ he was probably blown. Good kill, what's your setup? 491rwhp on an LS3 would be full bolt-ons and a small-ish cam right?

good kill

Smallish cam? Not exactly. The LS3 heads flow well, but NO heads are gonna pull near 500rwhp out of 376ci with a small cam. For that matter, from what I've read and researched, it's actually pretty hard to get a LS3 into the 500rwhp mark even with ported heads and a big cam. and nearly impossible for a LS2 6.0 running the L92/LS3 heads and L76/LS3 intake... though there are now two guys I believe that are claiming to have succeeded using massive cams and stage 3 intake and heads.

I got up to a least 130mph and I have a ls2 c6... Heads/cam unported fast...full exh.

the saleen mustang was a 99 on up model, the blown ones made 495 flywheel hp I think???

Irunelevens

In those years I think the basic S281 S/C was 365hp. They run ~high 12s.

gmhtp did a tec article i forget what month ill have to find it but they did a head/cam ls3 vette and made a little over 500rwhp they used wcch ported ls3s. Oh and awsome vette man 490 from a h/c ls2 that thing has got to pull hard! the 495hp saleen was the s351 btw

Sure they will. Its all about the combination. The cam just makes everything work together. Make sure your intake, heads, and exhaust are up to par and you don't need a big cam to make big power.

Ooops I've gone and said too much.

c6r

I have patriot heads believe it or not...polished them out which toke me 2 days per head and my cam is 238/242 ...604/610...115 lsa happy with the results...big power without shelling out the afr/trickflow head money

Sticks n Stones

I said naturally aspirated and implied on pump gas
Even with the best Trickflow or AFR heads out there, ported, with a ported Fast, you are still, unarguably, going to need a cam with a duration in the mid to high 230's and over .600" lift on a 112LSA or tighter. Huge flow requires huge cams to get huge horsepower... Though alot of times the huge cam setups would probably be faster with a smaller, more midrange torque providing setup.

Just so we get this straight since everyone has there own version of cam sizing: Mine goes like this:
baby cam is under 220 dur.,
small is up to 228,
midsize is 228-236,
big is 236-low 240's (and at the edge of streetable IMO)
and larger than low 240's is "out of my knowledge range".

EDIT: just saw your patriot head comment. you must have performed magic on them ports to achieve the 330+cfm intake flow required to run those rwhp numbers on a stock cube LS2. Nice.

Pretty much sums it up.

So was I

mid to high 230 duration and 600 lift is NOT a big cam for a 376cid motor.

We aren't talking about huge horsepower here, we are only talking about 500rwhp.

You guys need to look at the size of the motor before you decide on what is a huge cam and what is a small cam.

Sounds like a nice mild cam to me. That is just a combination that was thought out well.

ARCTIC '00

^^ I assume Sticks N Stones is refering to SBC/LSX since that seems to be the motor in question. I think he explained it quite well.

Hey Arctic when are you going to take the ZR1 back to the track? I want a few runs from a dig this time. I'm sending you a P.M.

ponygt65

incorrect. Only the S281E's were up in that range.
hig 12s is being generous. LOL

99-02 was 365

03-04 was 375.

woo hoo. LOL

Redfire 03

The S281-E was rated at 425 although it was pretty obvious they were a bit under-rated. The supercharged S351 was rated at 495.

Only good Saleen was the S351. 1999 S351 was the most perfect Mustang.
