Those were some proprietary Diamond pistons we had made for us in large runs. They were setup for 4.125" Bore, 4.000" Stroke, 6.125 Rod Length, -3.84cc Valve Reliefs. I believe their valve reliefs were setup for the ETP LS7 heads.

Compression distance was either 1.115" or 1.120"...I am sorry I do not have the exact on them because we haven't had a set made in close to 5 years.
