So I picked up a Mexican 302 motor that has 289 HiPo internals, and very cheap I might add. The guy got it from some old retired guy friend and was just trying to make a couple bucks on a flip. He didn't really know what any of it was. It has big pop up pistons and the motor is std bore with no cylinder ridge at all. So very few miles and the pistons can be resold. It had 67 289 2V heads with screw in studs, guide plates and double valve springs too. So somebody will want those I'm sure too. It has the right rods and crank for my HiPo project. No balancer, hatchet or flywheel though. I only paid $300 for it all. So worth every penny. I did ask him to go back to the old guy and ask about the balancer, flywheel and distributor. And to ask if he had any other heads around (maybe I get lucky and they are hipo). So we will see.
But my big question is, would it be a big deal to use the Mexican main caps on a C5 block? They have some extra casting numbers over HiPo caps. Or does anyone out there have HiPo main caps to trade for a good std bore Mexican block?
