Thanks for the replies! Without a doubt the 350 would beat the DZ-302. Those cars were absolute dogs until you had them wide open. By then the 350's already in 3rd gear half-way down the track. The 30-30 duntov was just WAY too much cam. if my calculations are correct, a smaller cam, such as the 270HR, will give you a much more streetable power band. The 350 still makes more hp and torque (especially low end torque) but the "L98 302" as I'm going to call it, isn't too far behind. Will a mild 350 still beat it? No doubt. Will smog 350s from the 80s beat it? probably not. It will be a fun little project however. This car is just a toy. When I eventually sell it I'll be going with a motor with more cubes. Right now, it's going to get abused
