That's pretty straight and looks reasonably rust free for our part of the world. I am curious how the Gamma Goat wheels impact performance with the stock 251. A bit taller should help to hold down the rpm's at a decent road speed. A good place to start with a runner rather than a body man's nightmare like a few of mine.
if the 4.89s give a 20% increase in road speed the goats give 15%. no noticeable drop in power. I mounted the goats to my truck with 4.89s and broke 80mph it was like driving a backhoe at speed she was bouncing from one side of the lane to the other the pucker factor was high with white knuckles on the wheel.....lots of fun
