i know, i know 750K top end on a F
« on: July 17, 2013, 03:50:04 PM »
I have been reading about it a fair bit and it seems like the info out there says two different things.  I have a 78 750F and a 75 750K, the top end on the F is pretty tired and needs work.  What I have read is if I switch out the pistons and cylinders I can put the K top end on the F bottom end.  This is what I have read, is it that straight forward... does it work?

Why not switch the whole Motor? It would probably be a lot easier.

Don't do this. Unless you're out of work, or a masochist.
