Does anyone have any idea what size combustion chambers these heads have? Its a 72 302 in a mercury comet. I am also curious why the 71 comet 302 2barrel had 210 horsepower and the 72 had 138 horsepower. Are the heads different?
I plan on rebuilding the engine in the car in the spring. I think it will be fun and some good hands on experience. The engine runs, but kind of smokes a little and is pretty gutless. Dont need neck snapping performance, I just want to be able to get on the highway without getting rear ended Thanks
