What changes have to be made on a 1974
Roadrunner 360 to 440 swap

1 Answer


The easiest way would be to locate a 1972 or older 440 roadrunner strip the 1974 of the drivetrain and install the complete '72 or older 440 drivetrain and suspension, engine mounts, transmission mounts electrical harness, just have the donor car there when you need the missing or different part on the '74 and change it.. the other fabrication can be done as needed exhaust system routing accelerator brackets etc.. all the small changes that are necessary to do this need MIGHT be offered prefabbed bracket "kits" or special exhaust manifolds that would fit.. I'm sure it can be done $$$$. most things are different on the '74..
