The head was milled .001 but no port work yet. Not sure what the tear end in but am pretty sure it’s stock base level 1965 for the original 170 engine.
I’d probably go supercharger over turbo if I had the cabbage, just because I’m a little old school. But either would probably mean new everything past the crankshaft, so no.
You could grab the supercharger off a 3800 SC Series 2 Grand Prix for a modest price. The General made a ton of those engines and they are turning up at wreckers now. Might need to fab a drive snout to extend for the belt drive.
