What would be the best tire height for an unknown hp 350 goodwrench with a th350 and a 3:08 rear-end?
Same question for a somewhat built 283?
I very rarely go above 45 mph. No freeway driving.
And then, which would better serve my driving conditions - the somewhat built 283, or a stock goodwrench 350?
