I own a 1971 Buick Skylark with a 350 4 barrel carb. I am currently in the restoration process and would like to rebuild the engine and beef it up a bit but I am having trouble finding performance parts for it. Engine swap is a possibility but cost is the main factor in this case. Is there a cam, lifter, intake, head, or any kind of performance part made for this engine or am I just wandering around in the dark? I found a rebuild kit online but options to upgrade were non existant. If anyone knows anything that would help it would be greatly appreciated.
