Yes JB, Shelby took the 4 cylinder WWI taxi engine out of the AC Ace and put a Ford small block 221 into it, then a 260, then a 289 and finally, the great honking 427. They shipped the AC chassis to USA and installed the American V8s in the USA.

The V8 heart was from over here, the ACE was from over there, the marriage? perfection.
