Guys,

I'm rebuilding a 1969 440 HP that was last rebuilt in the mid-90's. It's .030 over and has pistons marked TRW L2266F. The heads are stock 88cc 906's. Looking the pistons up, it says today's version are a 8.66:1 compression ratio with stock 88 cc heads. These pistons don't come up to deck height, so they probably are 8.66. Does anyone know if a TRW piston from the mid-90's is the same as today's version from Speedpro? Does that compression sound right?

I'd like to put the 440 back to stock specs including the compression ratio, or at least very close. I could live with anything from 9.8 to 10.2 as the final compression. I don't mind running race gas. What modern day piston would give me that or put me close? 8.66 sounds like a slug.

Thanks!!
