How difficult would it be to swap a C4 out of a 1970 302 stang into a 1969 351 stang. Will I have to change the bellhousing?or will my current bellhousing on the 351 work? Thanks!
Should be a direct swap as long as the 351 is a Cleveland or a Windsor. However, you may run into problems with the neutral safety switch, cuz I konw for sure that in one of my 73's the FMX has a much different switch than that, that is used on the C4. Maybe the driveshaft as well from the 302/C4 combo, since the C4 is shorter than the FMX.
