Keith is way ahead of me, I'm kind of doing a passive job at the moment - my plan is a mildly tweaked engine for the 3A, so I have prepped a spare 4A head, I've ordered one of those nifty Larry Young cams, and I have a set of 87 MM pistons/liners waiting in the wings for install. But the basic block is not torn down completely yet, too much other stuff going on.
