I have a 396 in a 72 k10 longbed with 3.73’s and 32 inch tires, th350. It runs well but you have to realize the weight of a 4x4 truck, the weight of the tires, and the effective gear ratio have a huge impact. You have the same effective gear ratio as a car with 26 inch tires and a 3.23 axle.

If we put your 383 in a 4500 lb wagon with 3.23’s and it ran like your truck does now, would you still think it was slow?
