Time to sound off...
I have the 422. You'll have no problem with a little work. First, get the heads ported and polished. Replace all rings and bearings (you'll need it for your new cam). Always use Lunati cranks. Set up a dry sump oil system. RESLEEVE your cylinders. If a machine shop tells you this is an unnecessary step on an LS1 engine for that size bore, back slowly out of there.
Here are the cam specs you need.
Intake duration: 294
Exhaust duration: 306
Duration @ 0.050" (I/E): 239/251
Lift: 0.570"
Lobe separation: 106
This will rocket your car in the 4000-7000 RPM range. The maximum safe RPM on a 4" stroke is 6000 RPM. You can take it faster, but you'll most likely see what piston smear is. Get a torque converter, and a PCM programmer who knows what to do.
Forged pistons and rods are a MUST. DO NOT use this cam on a 422 without custom programming unless you want to see two heads blow themselves to pieces.
Yes, it will lope. Yes, it will shudder. If you want to try something REALLY cool, called the import eater LS1 by my friend who built one, go with a bored and destroked block. He's got the same cam as I do, but he's running a 4.150" bore and a 3.25" stroke. It changes the displacement to a 352 CI, but you should SEE the top end. While he moves less air, he can safely sustain that baby at close to 7500 RPM, with no discernable damage or undue wear.
Imagine the joy of stomping that Supra with a naturally aspirated LS1 engine!
From a dig, go with the 422 version. From a roll, go with the 352. Better yet, have two Camaros and get the best of both worlds!
Never guess at your engine modifications. Do the math first.
Good luck, and happy racing.

to whomever said the supra is just an import, that is about the dumbest thing i have ever heard! the supra is not just an import, they are probably the most feared import from japan. i know a kid that has a 98 m6 supra that has dynoed at 645 rwhp with stock heads and cams! this thing is just insane. he ran a high 10 at the track, and now he has his head and cams redone to be about 850 rwhp or so now, so i cant wait to c what he will run! you probably say its just an import because you have never been in one. i bet that 900 rwhp supra would spnak you, so just give props to where they are deserved. and remember its an inline six that is makin all that power! even though it is turbo'd it is still just an inline six

number 1 68bird it was sarcasm number 2 no a 900rwhp is not going to smoke me unless it's a full blown dragcar. at my local track msp brings their supra there all the time so i know what an 8sec supra looks like you need to chill but as far as the street goes most high horsepower supras suck unless it's a roll you have to do almost a drag only suspension to make it hook i saw a supra with 834rwhp dyno proven get taken out by a fox body that ran mid 12's on the street before. most and before you go high and mighty i say most supras even the 800+hp ones run 12's to high 11's but trap ridiculously high. like i said chill man and if you have somone in a 900whp supra that's near va i'll run'em as long as they don't get upset by losing to an old school small block

Supra is only the most feared import because we don't get GT-R R34s here.
While i'm on the subject, Nissan needs to get it's *** in gear. we're at the apex of the second great muscle car/horsepower wars era, and they would have a guarenteed hit on their hands if they brought over a non-watered down skyline. look at how pressed people are getting over the sti and evo, imagine the frenzy over an awd sedan with real power. I think toyota would do well to bring something supra-like to market again as well. mid 90s was not the time, but now i think would be appropriate. i mean seroiusly, next year the mustang GTs are coming with 300hp stock, GTO has 350, and vettes will be sporting 400hp from the factory. even mid-level benzs, audis, and beemers are nothing to shrug off any more. to combat this surge in power from american and europe, nissan gives us the 350z, mitsubishi the evo, and toyota... what the **** have they got? the celica? the matrix? have they completely fallen off the performance map?
i for one would like to see some real cars out of japan again, if only for competition's sake.

hey i was just stating that fact the supra are a bad *** car and they are a force to be reconed with. my buddy has one and it is funny as hell when he has a bpu+ car nad my stock 89 formula 350 can keep up with him from a 40 roll. i love it
and the r34 gtr is not the most feared, the r32 gtr or godzilla is the most feared. stock to stock the r34 will fall everytime. the rb motors are one bad motor as well tho, i would love to beable to see one. so i can show them that my 68 ls1 will put the smack down on them lol.

What does your friends Supra run? 900rwhp can mean a whole lot of things.. Find out what hes pushing at the track so we can more accurately give you a depiction of what your new setup will need to be.

no not my buddy, this other kid, but you know you say something then you go back and read it after you wrote it and you say why did i say that lol. but my friends is just bpu+ which means he is supposed to have about 410 rwhp, but after ridin in it and what not, i really dont think so. but he still is gonna put a stall in it, so it might be pretty nasty after that. he said he is supposed to beable to run a 11.9 or so once he gets his stall but i dont know.
as for my setup in the 68, i will have shortie headers since longtubes wont fit, ls6 intake with 28 lb injectors, most likly all the other bolt ons, a yank 3600 stall, and i was thinkin about the stealth II cam, but i dont know. what do you think that setup will get me at the track with a set of dr's or slicks? thanks

CCW wheel package with MT ET Street's and skinnies...
IF an auto, send it to Rossler and get a good converter, 3.42 gears
IF a 6 speed, a good clutch and hardened output shafts, 3.73 gears
427 sleeved motor (many vendors) and 250 shot of N20 (need COLD plugs, 108 ocatane unleaded, good tuning, timing tuner for window switch and timing retard)...get a cam with up to .600 lift and about 244/236 duration (split but not reverse split)
NX GM MAF kit (NXL kit doesnt work well yet) dual stage 100 and 150 hp settings
HAL shocks
Varram air intake
should run 9's at the track and with a 250 shot, and no turbo lag, it should be great at a roll
