What motors would work with a C4 transmission?

Its a 1977 I believe. The car is a 1969 Ford Galaxie. Has no motor. Tranny is good.

If its a factory car it will be a 260 v8 and its a close relative to the 289 / 302 windsor.

just about anything will fit into a galaxie. Except a f250 diesel (too wide)

yes there are a lot of ford small blocks that used the c4 trans

Many motors are going to work with that tranny. However the better question is what bell housing do you have, and what bolt pattern is it. Ford has used many different motors to mate to that trany, The 289 and 302 being some

It's the stock transmission, it will be a C6 not a C4.
