i like to bring my 66 barracuda back to the road and have a good running 318 left and also a set of good x heads and a tight budget . My 318 has a breathing problem so i thought i go with a mild cam , put my x-heads on it 4bbl carb (650 ? ) and a set of spitfire headers which i am allready have. What do you think can i expect from this ? Around 250 hp ???
