340 A body versus 383 B body

Sorry, NOT. Owned them all raced them all. You ever run a LT1 or a 327/365. I've had them also these little small block chevys kicked ***. Sorry the stock 383's magnums were just plain heavy dogs as were the 390 fords. Now I know they can be made to run my freind with his RR all steel 383 went 11.20's in the early 70's.
Sorry, lol on the street stop light to stop light the 383 won. Left them small blocks like they were standing still.
