piston t3021 hc 060 do thay come with pins and what is compression ratio when installed in a 1923 t engine.Do you have to do any thing to any other part of engine.
The high compression pistons come with wrist pins. The compression is comparable to adding a high compression head which would put you at about 6 to 1. You do not need to do any other modifications.Date Added: 01/22/05
