A few years back I was involved in something similar but different. I was selling my Original 1966 GT 350 engine because I swapped in a BOSS 302, funny thing is I found out who owned my car and he had no interest in it. OK so now what, an original GT 350 engine with all the best parts and the original numbers? At the time some ignorant folks... Not the sharpest tools in the shed- would chime in and say OOOH Look, it has a Fram filter on it, and a Dual quad Cobra intake, and painted black... Really? I still cant believe how some people just dont get whats important in life, to a numbers person it is very special. Mine was sold for another SHELBY needing a new heart transplant. Yours would probably be in the same situation. There are still a few cars out there needing that engine . Best of luck on the sale.
