The original 301 came from a beefy 350 with 4 bolt mains and a heavy duty crank. To make CAFE guidelines The block was lightened, It went to 2 bolt mains, the crank lost 2 counterbalances ,
and the ports on the head got smaller. if it couldn't breath, it couldn't burn gas. If you forced it to breath you could force it to kill itself. I was thinking a light (modern production ) V8 or even a healthy 6 would make that a nice car today. Not worth the effort. The weight would be low, the power high (higher) While not up to current technology it was a good handling car for its day!
