86? 87? Top end? How to tell
#1
I know the guy I bought it from did some engine work? It has a cool head etc.. But I thought that he did the different bottom end with a different top end thing. Is there any way to tell what cylinder I have on it? I need to do a top end rebuild and need to figure out what piston to get..? Thanks for the help!

I understand that. And when I pull the top end I will be able to tell from the old piston what bore etc... My only problem was is that I see when you buy a piston its asks what year? I wasn't sure if it mattered on the top end or not? I know the bottom end is different over years but wasn't sure if that was all? Thanks for the help!

When you clean off the top of the piston there will be a number there telling which piston it is. You can also tell by loosking at the piston. The 6 and 7 on the intake or exhaust side will be cut in a half moon shape. The 8 and 9 will be straight across. This was done because of the bridged and unbridge cyclinder. But go with number on top of the piston.
