So if I'm understanding correctly, and doing the math right, a 408 stroker can be built utilizing a stock 351w block and the stock rods. I've been doing some research, and can not find any threads anywhere talking about this. But the math seems to add up, so please correct me if I'm off somewhere. The trick is to use Boss 302 pin height pistons (1.53"). (Block height) - (stroke/2) - (rod length) = (piston pin height). Sooo, 9.503 - 2 - 5.956 = 1.547". If compression ratio is an issue, could a domed piston or thicker head gasket solve that? Please help or guide me in the right direction.
