The old Chevy straight 6s were another of those motors. You couldn't kill one if you tried.
A guy I grew up with, back when we were teens, had a 70 Nova with a straight 6. He wanted to put a 350 in it. His dad says not until the straight 6 is junk.
Well this crazy fool decides he's gonna help the straight 6 along, and takes all the water out of it... He drove it around for nearly a week with no water and it never locked up!!! WTH!?
The motors you don't give a damn about always seem to run best and last the longest.
