Several years ago when we assembled the silver car the only Z11 motor we had available was a top half on a 409 short block. We're going to replace it with something more suited...more like a match race motor. So it's "out with the old"
Just a simple switch-a-roo. The new motor will be a 4" stroke...suits a 63 better. The original motor will be going into the red 62 Belair...where the 409 short block is appropriate
