I disagree that a Ford would be that much more difficult than a Chevy. After all, the 289/302/351/5.0L motor has certainly been available for many years, making interchangability simple, and the engine has been so popular for so long, finding parts is no problem. And of course that way you don't have to be seen driving a Chevy
351 windsor and 351 cleveland parts are not all swapable.chevy parts are 350 283 400 parts are.we just made a 383 small block with a 400 block with a 350 crank with bearing spacers and rods . very easy and less than $1500. if you know how to.
