Shoot, one teenage burnout 50 years ago could put a diff on the die list decades later.
As far as 7.25’s go, I did multiple 100 yard burnouts for 5 years behind a 318 and then 1 or 2 years with a bit over stock 5.9 Magnum and the 7.25 never blew up.
(Yea I felt pretty lucky)
I thought 7.25’s didn’t come in Coronets at all. Hmm
But I’m not a Mopar historian either, so there’s that.
