I would think a 4.11 or a 4.30 gear would be good with that big of a motor... :-k

I'm with Barry on the rear gear.  With all that blower torque you're not gonna need that deep a gear.  4:11 sound about right from here, especially iff'in you're running some big meats on the rear.

Think I might even go for a 3.89 with a blower, they just love pulling hard..

with a 32 inch tire too.

I have seen a 4 door Chevy II wagon made into a 2 door. Glass doors and front end. It really looked nice. I always wanted one.
I asked about weight because I am always measuring my combo against what others are running. I have been considering a gear change.
