Hi,
Another update!
I've just been advised by my machine shopt that it would not be a good idea to bore to 4.13!
So I think I'll stick with just boring enough to clean up, put in some new pistons, bearings etc.
I think I'll hot it up a bit with a new cam and rocker gear along with some porting, polishing and balencing.
I was thinking of Comp Cams 282S grind with dove roller tipped rockers, anyone had any experiance with these?
