HI All. I just wanted to know what the differences between 36 and 40hp pistons were. I think is the wrist pin position and skirt length but Im not sure. Ive been offered a set of NOS 36 pistons for too good a deal and I want to confirm theyre not 40's. (no box) Any tips? Thanks

Yep the piston pins are different

Its not much use getting the NOS pistons if there Stock size You need to get 1st or 2nd oversize so you can bore the barrels out to match

I probally wouldnt buy if there stock as all teh barrels you find are S/Hand n oversize as well.
