jongdoe said

you guys all know alot more about this then me. i appreciate all the help. if the only things i change in my 73 340 engine is the pistons and cam to the 1968 specs would i be improving the performance? any idea about what hp and cr i would have while using my stock 70-72 cc heads?

If you use a set of these with stock J Heads you'll end up with somewhere in the ballpark of 10:1 with a 72cc chamber and a .039 gasket.

Of course if I had the chance to do it again(which I will) I'd sell that 340 to someone that thinks they need a 340 and sink the bucks into a 360.
