ford351m Welcome to FTE & the Bumpside forum 
Yes sir many times. The 360 is a 390 bore block engine with a 352 rotating assembly. All you need is a 390 crank and rod set with new pistons properly sized and you are all set. Piece o cake.
Add an RV cam, shorty headers, a small 4 barrel carb and you will have a stump puller. Stay at 600cfms or smaller on the carb.

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!

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.

i agree with above. 390 is much better the a 360. not only performance but believe it or not it will even get better mpg if you tune it right and put the right carb and exhaust on.

i'll disagree about the 750 being to much , i've had three carbs on my mild build 390
600 vac sec, 650 double pumper and the 750 vac sec
600 was good , 650 bogged 750 runs like a scalded dog

Cool that you got one to work. I'm sure the 10:1 compression ratio helped ya. For my own info, do you remember which color spring is in your secondary diaphragm housing?
