I just picked up a 402, casting # 3969854 sept 69 date code. I'm looking for ideas for pistons, rods, cam, and heads. The motor was complete, but the pistons were jacked up. Heads were 3872702, pistons are trw forged with the # 3969974 stamped on top. The cam is a Clay Smith hydraulic flat tappet .570 lift, 244deg @.050 with a 110 deg lobe centerline. And a holley 850 double pumper. Intake manifold is an edelbrock torker 2-0. This motor would only run on race gas because the compression ratio is outrageous. I plan on droppin it in a 67 camaro with a 5 speed manual trans. Money is not too much of an issue, I can always save. I would like to keep the cr around 10 or 10.5:1 maximum. Gear ratio is 3.08, but i plan on a 9 inch with 3.73 or 4.11. I would appreciate as much help as possible.
