I currently have a 1965 Plymouth Sport Fury with a 4 barrel 383 ci, this is completely stock and the engine as far as I know has never been cracked open. It has 115,000 miles on it and runs strong. It has the original exhaust maifolds, however, I did put on a 2 1/2 inch duel exhaust from the manifolds back and put a new Eldelbrock carburator on it last spring. This engine, per MOPAR , is rated at 330 hp, there is no way that I am there today. The engine is tierd, it does not leak or burn any oil. This is what I plan on doing once I get the car out of it's winter storage hibernation. I was going to pull and rebuild the heads, and while I have the heads off put all new lifters and push rods and do a little porting as well. I really don't want to mess with the cam, this is a little outside of my mechanical ability. Here's my question, by just rebuilding the heads, swapping out the old with new lifters & push rods, and do some porting, I should be able to see a noticeable gain in horse power, right? I really don't want to pull this engine, I want to be able to keep this task within my mechanically applitude, I probably could do it, I just don't want to get into a can of worms. Thanks
