Hello all. Im about to start upgrading the engine and need some help. I want to up the "umff" out of my 2bbl 350 but dont know what would work well together.I want to keep the original 350. Every thing is stock except for dual exhaust and flowmasters 40's. What kind of carb, headers, intake, and cam should I look for? Keep in mind this is a daily driver, that MIGHT see some runs at the strip. The guy i bought the car off of ( 2 months ago acually) said he changed the heads to run pump gas (87 i think not quite sure) Is there a way to check which heads it has? He also said he made the engine into a 396 when he had it overhauled so i dont know if this is true, and can't get ahold of him to ask him question about the rebuild. Any help?
