Chevy in a 55
I considered this swap before going to a 350 Pontiac for my 55 Safari. The Ponty is a lot easier and will bolt onto the orig front mount and a rear mount is relatively easy to fabricate. Orig ex manifolds bolt right up so orig ex can be retained. There were issues with ex manifolds fouling on the chevy as its tight around the front suspension and steering box. I suggest you bif the chevy and look for a 350. By the way if you want more oomph the 400 and 455 will bolt in the same as they are the same physical dimensions. The 400 is prolly the better engine although there will be those who would argue thet point!!
