+1 on what blown99 said. ARP is best !

Depends on what your doing with the 402 which should be 4 " bore and 4" stroke.

You need to calculate your comp ratio on what type of Pistons you are using and the chamber size of the heads !!

For street, I'd shoot for 11 to 1 or 11.5 to 1 !

Yours is 4.010" bore, James. Your pistons should be right at .005" out of the hole as well.
