I was on the freeway doing about 70 and my rpm's were a hair under to right in 3k. Truck is a 80 Chevy 350 with 31 by 10.50 tires on stock rally rims. Any idea what gearing would be in the rear end? Would 35 by 12.50 help lower that rpm down and make it more happy at highway speeds or would it make it worse? If it would make it worse what gearing should I look into putting in to regear the truck?
