I seriously doubt a today's FE 427 would do that much better, how could it?.

It was unthinkable then also.........Watched a NASCAR legends show a few weeks ago and Jr. Johnson,Ned Jarrett,Richard Petty,the Allison brothers and a few others all stated that they began to get real worried anytime the rpms got near 6,000 when they were running the 427's........During test sessions they would come in and ask for a rear gear change......they also showed old race clips where they would raise the hood during pit stops and add a couple of quarts of
oil in the middle of a race!!!!!!!!!!!!the leading cause of cars falling out of races back then was Engine Failure not wrecks......In one race at Talladega almost half the field fell out with engine failure using the big blocks. the drivers said things changed dramatically when the switch to the small block engines were made, engine failures were cut in half right off the bat.............
