Anyone got an old TRW piston catalog? I have some sbc pistons that I can't find any specs for online,, I think they are 2457 and 2458 if I recall, angle plug dome 350 pistons. I am guessing they were made to work with specific heads, need to figure out exactly what I can do with them.

Thanks!

Oval track and Racing w/5.7" rod and stock stroke. Comp ratio with 57cc head-14.0, with 64cc head-12.5, with 68cc head-11.8, with 76cc head-10.7, that's with .005 deck clearance and .039 compressed gasket, according to TRW circa 1989. The 2457 number is for cyls 1,4,5,8. 2458 for the rest obviously.

Thanks, had the pin height figured, and was pretty close on compression. I was curious if they listed specific angle plug heads they were supposed to work with.
