Fixing to acquire a '53 GMC 400 with a 270 in it. I already a few stovebolt chevrolets and I am wondering what parts - if any will interchange between these two engines. Looking at picture on google images it looks like there may at lease be some parts that do interchange. The cylinder head looks entirely different though - but do they interchange? At first I assumed the GMC engines (248, 270 & 302) were completely different, but now looking at the pictures it doesn't look like they're very much different than the chevrolets. Just curious.
