Thank you Rocco for this one!!! When was the last time you saw a centrifugally supercharged 1978 Cadillac Seville, powered by the Olds 350? Yeah, that’s what we thought. We can’t make this one up. This is crazy amounts of work for a car that most people have no interest in. With that said, this thing is done very nicely. Nothing about this says hack job, and we kinda like it. I could totally see McTaggart cruising the hell out of this thing. Check it out.
