Topic: 550 motor in a 350 frame

[mack82]

i have a 350f project goin on right now but i have a chance to buy a 550 motor cheap.  the motor is off of a '75.  will it bolt in a 350f frame?

I have both, and I really doubt it would work without lots of cutting and welding. The 550 motor is quite a bit bigger than the 350. I haven't tried it though.

The 550 lower engine mount lugs are about an inch wider than the 350F frame.

Not worth the effort.

Buy the cheap 550 motor.  Find another buyer willing to pay a little more for the whole motor.  Or part it out and sell the pieces here in the classified section.  Use any excess funds to work on your 350.
