As long as you dont get carried away with carb size like leddzepp said a 390 would be fine I would think. I'm gonna do a cam swap and a Holley economaster which I think run around 450. They built them for gas milage during the 70s, but the small butterflies help with torque. I've only had them on small blocks in the past but I think it will work great on my 292. After all I'm only 10ci from a 302 and they came stock with 4 bbls.
