318 parts list

I used KB399 dome top pistons in my 318 so I could run 915 J heads from a 340 without decking the block, ordering custom pushrods etc.

Chambers were 70cc with 1.88/1.6 valves.
I put 2.02/1.6 valves in and the chambers became 66.5cc.

My Compression ratio ended up being 10.39:1 without taking anything off The block or heads.
