Also, if you are using an older block be sure to test the walls for pin holes. I personally got burned by the pin holes twice.

My build is a 1967 302, which did use a 657 2 bolt block as I have, my heads are also 462s the only difference between my block and an original 302 block is the code on the deck. I did sonic ck my block after cleaning, I think it will be ok, hoping for 400 HP on the dyno.
