360 Magnum engine

Sorry had to quote you...Stockers around here are all using Dana 60s.....which can be ordered with or without provisions for pinion snubber...and I would say,,,,99,999% of the stockers use Cal Tracs which probably means they do not use pionion snubber...

I thought the rules said that you had to use a factory manufactured rear end from the factory that was made for a car.
Which to me would mean a Dana that was manufactured for a b-body or an e body or station wagon that had been narrow to fit the a body. Or the a body Dana that direct connection made.
But if what you say is true I already have a 52 and 5/8 Dana that I could shove under mine. I would rather have the Dana than the eight three quarter even though I'm running a 904 with 8 inch converter with the low gear set in the 904.
I have slide-a-links.
