Hey guys I had a few questions about running boost on a lsx motor, I currently have a Ford R302 based motor that I have not yet run and I may be picking up a 98 T/A soon so I had a few questions about building a boosted lsx motor for it. Back when I had my ls1 there were alot of issues with boosting a lsx motor, I used to hear of head lifting all of the time and such. I was curious if I wanted to build a 1000rwhp motor what would I need to run to keep it reliable, I was thinking iron block, forged internals, afr or dart heads (thicker deck should help hold the headgaskets) I am not sure what to do about head studs, what size are stock ls1 headsuds, should the block be tapped for a larger stud to help keep the head down? I am using Parish's truck as a major reference, as far as I know his truck has been extremely reliable making 1000rwhp but I am not sure what his combo is. If I cant come up with something that will hold maybe i'll just drop my r302 motor in it *gasps*. Anyways I searched and couldnt find alot of info if it's out there let me know.

PArish is running a 408 with a t88 I think..

and studs will greatly help hold the heads down..

stock ls1's have head bolts not studs. studs will def. keep the heads on. you should not have a problem if you lower the compression. alot of guys put on the 317 castings and have them ported and polished with bigger valves.good luck

From memory, parish's truck is a W2W motor. I think he ran 23psi and got 1000hp. If your looking for 1000+ theres no better place than W2W for a shortblock.

personally, id do the 1/2in studs for safety, although im not sure if he is.

He's also runing MS for Fuel and the Tranny is a 4l80e.

Parish is completely redoing his turbo setup right now. Hes gonna run twin 70's, i think.
