I have srp's in my race motor. Its a 13:1 with 150 shot of nitrous. These pistons have an 11cc dome and they sit below a 62 cc combustion chamber. I have had good luck with srp.

SPR is an excelent piston. We use these up to about the 200-250 HP nitrous level. Then we move up to JE's.
Let me know if I can help.
Thanks,

I was looking at doing this sometime in the future and my latest Jeg's catalog came in the mail. They now carry SRP's-I was benchracing PN #867-138089. They are 11.8 to 1 with a 58cc chamber flat top. Only ~$450. I'm sure 2FST4U could do better though...:)
They seem to be the piston of choice for many-fairly tight piston to wall clearances and overall strength. I've only used TRW's so far though...

No Go,
if nothing else you'll like for the piston to wall
clearance, there are better for not a whole lot more
dough but like 2fst4u said small shot nos or no
extended high rpm(like long round track) there
a good buy.

hey chris,was wondering what srp to go with considering the compression ratio for an LT4 is alraedy 10.8to1 ?? i saw i new jegs catalog with maybe the right piston for me but cannot remember the pn# ?? also looking for a set of gears and may consider anything between 4.09-4.30?? i hear that 4.27-4.30's put you at the end of the 1/4 mile right at the top of the rev limit for an

I ran SRP in my previous 396 motor. I am going with true J&E with the most recent build up. I want the ability to throw more juice at it later. The SRP are good to about a 200 shot from what I have been told. If you are not going to go more than a 100 shot on the motor, the SRP are an excellent choice.

I have Speed Pro Hypereutectics in mine, Scat 9000 stroker crank, 5.7 Eagle I beams, you can run a little tighter wall clearance over the forged.
