I have been tempted lol however I dont want the hassle of shoehorning one of those in there the first time around. and also I got the LT1 for it for free so, a bit of the $ i would have to spend is already taken care of. BBC+1963 Chevy II is not something I really want to take on right now. I already have to figure out how to get a 426 HEMI between the fenders of a 1933 Plymouth very soon
