piston identification

[DianeS at speakeasy.org]

Hi Guys, I was wondering if someone out there could help me identify a set
of 350 pistons. I was told that they are 'Federal Mogul' parts and the part
number is

H618 P 030

I was informed that the 030 meant that they were oversized, my machine shop
wants to know the intended compression ratio, they were with an engine I got
with my project car, a long long story. They told me that they looked high
compression and that I might be ending up too high a compression for a
street applicaiton.

thanks, Diane
