As for a cam for the LS1-
I think im still going to go with Trick Flow heads
and have Comp Cams make me a custom grind for my LS1 going off my cam spec's i had in my LT1
230/236@.050 Duration .555/.580@112LSA Figured on a 1.5 ratio rocker.(however, if i convert the lift from the 1.5 ratio to the 1.7 of the LS1 the exhaust comes to like .697 - so i really dont think that is gonna work haha.. I'll have to get the lift spec'ed straight for the 1.7's...
I think that should be a pretty nasty yet very streetable cam along with Trick Flow heads, supporting springs, lifters & pushrods, LS6 or FAST intake, throttle body, ported MAF,36/42lb injectors, Pacesetter LT's & ORY,magnaflow Catback, SLP lid,125 shot and a 3200 stall??
Opinions please anyone who OWNS an LS1....

you won't see 500whp out of a stalled auto 346 on the stock short especially with one of those crossover style intakes. when you get done chasing that kind out of power out of a 346 you would've been light years ahead to start with a 6 liter junkyard block, have half the money invested, and have something that will last vs. a stock short piece. i also believe that stall to be too small for a 230/236 112 lsa cam. any ls1 h/c combo will run well with a proper tune. if you're dead set on using a fast setup, i'd opt for a ported 92mm setup from a sponsor like vengeance.
if you want a "max effort" 346 setup, be prepared to find a th350, 5k stall, and vic jr intake. otherwise you are wasting your time.
if you want a streetable setup that will make nice power...trickflows are a great choice, but remember you need shaft mounted rockers to use those heads. if i were you - i'd port/mill some 243 heads, flycut the pistons, and do a custom 224/230 110+0 cam. xfi lobes. great low-mid range and would scream on top end. i think you could easily get away with a 3600 stall with that cam. intake is up to you, but i don't think the fast setups are worth the money. stock maf and tb will support 500+whp, as well as the pacesetter headers.

the lift will be determined by your choice of lobes. typically a cam that small on the duration will settle somewhere around .600 lift unless you run an lsk or lsl lobe...which i would not suggest.

Everyone knows my "defenition" of "streetable" is a far cray from what pretty much everyone on here likes.
I am happy as long as I am not worrying about valvetrain failures every second the engine is runing and as long as I am not worried about the fuel pumps cooking to death.
Just fine with a big cam, big stall, gears, race gas compression, and a glide...
My last cam was for great mid and upper RPM power and competition use. From a roll or a stop when I nailed it (no T-brake) the car was instantly at about 4,000 ish RPM on the motor (nitrous stall).
Why would I care about bottom end if when I nail it its allready at 4k?
It still did just fine cruising and I could pass people with ease using very little throttle, even in a third gear pull the car would move good, it did not matter what gear it was in unless I was racing.
To many people think that by going to a mid to upper RPM cam that they will loose all the bottom end and you don't. Build the car right and its going to be fun no matter what the RPM is.
3200 stalls are daily driver stalls if you ask me, any kind of real power and your talking 3800 and better.
Jeff, with what you wan't I doubt you will be happy with that direction that your are wanting to go.
For what you wan't I would just get a vic jr so you will not have to upgrade down the road.
Don't waste your time with a TH-350, get a 400 and forget about it. Id sell you mine but James is going to take it.

They hide this kind of information in books Jeff. LOL!
That was lake placid btw.

There you go read on up chief. Although I think now you realize that 500 rwhp is kinda more of a pain to get rather then just buying a larger CI motor that you could run a more conservative less peaky cam on and still be at 500 hp. You want 500 hp get a supercharger or turbo and your set with minimal mods just gotta build up everything else but thats a whole nother can-o-worms.
My final word. Read, Read, Read, Read, Read, Read, Read.

Jeff, I will sell you my 468 minus the heads for a good deal, you know how it ran on 7 cylinders and pump gas.... It has held a 300 shot a bunch of times no problem.
Will even throw in the ignition system minus the coil (sold it), new plug wires, dapner, everything....

230/236@.050 Duration .555/.580@112LSA Figured on a 1.5 ratio rocker.(however, if i convert the lift from the 1.5 ratio to the 1.7 of the LS1 the exhaust comes to like .697 - so i really dont think that is gonna work haha.. I'll have to get the lift spec'ed straight for the 1.7's...
That cam would have a lift of .629/.657 with a 1.7. The exhaust would be too big more than likely.

The truley big bore stuff is with aftermarket blocks............
James, this 402 you speak of.... I assume you are talking about average built cars?
My buddy Pete was supposed to call you on a rear end.
I want to run Jeffs car when we are all back out, Ill even pull the bottle.....
