My auto tech teacher told us in the mid 90s " a small block Mopar is a cheap imitation of a small block chevy" keep in mind back then no one loved Mopars except a small group of car guys. And any mopar worth having back then was a big block car LOL! different times for sure. Not saying the shop teacher was correct that was his opinion. thing is mopar has good stuff lik ethe shaft mount rockers...ive seen more issues with stud mounted rockers than Ive ever seen with shaft mount.
I think I've said it before but I'd take the 383 more HP even in early 70s smog form
