I've got a brand new in the box Edelbrock timing chain I'll make you a great deal on.
I have an '83 cutlass that I raced for years stock. Even won a champioship with it. I have a 350 in the garage that I was going to build for it. But I built the altered instead.
Chevy engines are cheaper but it is cool to keep the same make of engine in the car if you can afford it.
