Looks great
Opened up my motor- block destroyed. But part looks good . My motor sucked water- thought only one rod bent . But I bent several and broke block

Miniature Piston Assembly
Very nicely finished piston/rod example to compare size differences between engine components. Goes good with my other LS & SBC engine components.
