Big block Chevy's do sound good and by the way, my running buddy had a stock 67' Coronet R/T that had no problem with the Chevys. I imagine that if you'll check, you'll find stories going back and forth on who and what would beat who. Back in the late 60's I blew the doors off of an Olds 442 with a 66' Charger sporting a 4 barrel 383/4sp/posi and it was pure stock. We all have our stories.
