Is a stock '55 differential really "that" fragile?
Back in the 70's my uncle ran a 4:88 geared sock rear with an early posi unit in a 55 BelAir post.
He ran cheater slicks, a 4 speed, 12.5:1 .060 over 350. He ran mid 12's and says he never broke
anything in the rear end.
I am wanting to run a warmed over LS1 in my cruiser. It won't have wide tires and will have a
4L60e. Am I really in danger of destroying the stock open 3:55 rear?
I realize I won't have a posi, but do I really need to worry?
