I'm in the process of installing a super six intake/Weber carb and electronic ignition in my slant. Already have a 2.25 exhaust. Engine ran well and doesn't smoke but was lacking power. I just picked up an engine hoist cheap so considering pulling the engine to replace the timing chain, oil pump and adjust the valves. There is also a large dent in the oil pan that I want to fix. Anything else I should address? Worth doing a cam swap?
