Thank God you guys weren't around when hot rodding was just getting started... we'd all be discussing how to get better fuel economy out of our Maxwells.
If he was of that "old rodder" mindset he wouldn't have asked for opinions. He had the good sense to, potentially saving himself a lot of headache and expense. "Those 401s" are heavy, won't fit easily, and the oiling system and any real performance seems to have been an afterthought. So at least IMO, poor choice. The oldschool rodder would just cut and weld until it was in and running. And running poorer than any 360 swap with a mild cam.
