How strong is a Stock 50 Olds rear end? Motor options i have...Whats in it might run???? maybe...

The coupe has a 58 Olds in it??? maybe he's not sure what it is. might find a 303 for it, If i get the 58 Olds J-2 a runner a friend told me about, if he will sell it.

If i put the 429 - 340hp 66 Caddy motor i have - it's free > 10 t0 1 compression. Or ???

any other rear end that guys use in them? or keep the 50 in it.

I have a 77 Cutlass posi rear end a buddy gave me 5 years ago. just sitting there. I think on the Caddy swap the two cars factory curb weight, theres a 990 lbs difference in my favor. Cast iron trans case, Alum. turbo 400 would be a wash. just in the planning stage now, got to get it home first...........

 

I say do it..

 

Not very.

The 88 drivetrain was designed for use in the '48/earlier 76 series. Axles, U-joints, and engine mounts, were not known for their longevity.

What is your thoughts on the 77 Cutlass posi rear end?
strong enough and will it fit?

 

I don't have any.

Short for "Positraction". The marketing (Each manufacture used its own) term, Chevrolet used for their limited slip differential.

Olds called theirs, "Anti-Spin".

It should.
