[68post]

Oh Boy !! It should make 550 ftlbs or more. Be careful of getting any good traction because that 12 bolt is a weak cousin to the passenger car 12 bolt.

I have alot of Olds parts and engines on hand, just none for sale. My moniker "68post" is for my 1968 442 post coupe that sits in my garage.

You're gonna have a ton of fun sliding sideways. But the 455's don't take high rpm well without some changes, I'd set a rev limiter to about 5,200 rpm and ENJOY !!
