    i'm gonna say easier and cheaper would be the 302, more unique the 390, but you gonna need to do alot of modifications to fit it into the engine bay

    i do believe that you will have to do a mustang II front swap to drop the 390 in,and lose the towers alltogether.best bet would be to beef up the 302(stroker) or get a 351w and notch the shock towers.good luck in whatever way you go(y)

    You can go 390 by notching the towers, but it would be a whole lot of work for what you will end up with.
    If you were to notch the towers, it would be better to do a 393 or 408 Windsor.
    You end up with the same cubes generally, but the power to weight ratio and power to dollar ratio will win in a major way.
    If you don't want the trouble of expensive headers and notching the towers, then a 331 conversion on your present engine is the best bet.

    Plus you can build a 302/351 much cheaper than an FE motor.

    If you 'throw' a 390 into the engine bay it will bust the shock towers anyway!
    It's a heavy sucker-like said above-expensive to build too.

    Stick with the 302.

    The 390 is an awesome engine for a truck, but for a mav id rather have a 351. what happened to the truck? maybe you should look around for a high boy as a second vehicle. i put an 11 foot camper on mine and tow an 18 foot boat, doesnt even notice except that it sucks a little more fuel.

    Since it came out of a truck,99% chance is was a 360 anyway.
