the internals were y7 on the head only i was running b7 internals on the block.
y7 r0ds dont fit on the b7 crank. and rod length would be too big for the b7 block.
the pistons themselves i think would drop compression if installed on the b7 rods so not worth it. and im not even sure the wrist pin size match. hope this info helps you out. and sorry for any misunderstanding.
what rods are you using on your mini-me setup....im planning to go z1 block, with y7 pistons, and z6 head....i was wondering what the numbers looked like...tuned?
