torque box's

A substantial difference I'd think ...we're talking stock of course...
Huge decrease in engine hp/tq from 68 to 73.
No big blocks available. There's most of the losses...plus emissions, safety standard changes, etc.
You couldn't even get an 8.75 rear after 72.

Love the 70s 360, but not in stock trim. Beyond not exciting to me.

Got a couple 360s in mopars and another will see duty in an old ford so it's not a bias.:D
Ok, fine. No doubt, the earlier engines were more potent. We don't need to argue over what constitutes a "huge decrease" in torque but IIRC, they're within 20 ft-lbs (~6%)of each other.
