Question Motor mount brackets to frame

Hello,

I'm looking to put a 390 in a 77 F-150 that has a 351M in it. Questions is, do I need to change the 351 motor mount brackets to some FE style 360 - 390 brackets and will they fit in place of the bolt holes in the frame?


Thank You
OJ

Yes you'll need to change the brackets and yes there are already holes for them in the frame.

So the other brackets will bolt right up to the existing frame holes?

Yes, there are two sets of holes in the frame to accomodate all the various engine brackets.

Same with the transmission crossmember... there are two sets of holes.
