Has anyone stroked there 360 to a 390 and is it worth the extra money
Worth it? Check this out. Ford's 390 came from the factory with real close bore and stroke numbers as what the Bow Tie Brigade now build their 383 with. They are all so puffy chested about it being a torque monster. We beat them by DECADES!
Way too much carb for that engine. Better to keep it to 600 or less, 5-550 cfm would be better. It will run the 750 but not burn the gas.
jowilker is absolutely correct. If your 750 is a vacuum secondary with a black or brown spring so the 390 never sees the whole 750 CFM kinda maybe. But I stand pat with jowilker. Too much carb equals low efficiency. Bad gas mileage. Low power.
