The Ford Barn

With the change to ball joint front suspension in '54, I seem to remember that there was enough change to the car that there may be some oil pan interference and it wasn't a very happy swap. A "Y"-block is not a "small block Ford"; that is is the 289-302 series. They are smaller lighter, more powerful, and fit better. The money you will save by not having to buy a transmission adapter will quickly go for buying engine parts. Then if for some reason you want to add some "go fast" parts, you'll really be under water.

In this day and age, a "Y" block swap is not a good idea. However, if you have some nostalgic, "back in the day" reason for doing it, go ahead!
