[QUOTE="598, post: 15886998, member: 71706"] Boss 302 block, crank and rods were lots stronger than a stock 302. Heads were basically 351C 4v with a modified water passage. And Cleveland 4V heads were a little too much for a 351, yet alone 302. Too big of an intake port and a funky exhaust port that only really flowed on the top side of the radius. You would need to source closed chamber heads, as they also had an open chamber version that would give up too much compression, and the 73-74 4V heads had a smaller valve. Intake is boss specific. Only reason I could see to fake one would be for looks, and I think you would be disappointed, because those motors needed lots of RPMs, and fuel. Make much more usable power with a set of AFRs, TW, or comparable heads and a stroker kit. [/QUOTE]
