That's right 383! Runs great! Fresh engine out of a Roadrunner! Truck needs a little body work (paint, floor pans, windshield) I have the new floor pans. Just installed an HEI distributor, new wires, plugs, and oil change. Ready for the right young man or old gear head to finish. Turns heads and runs awesome. 727 trans shifts good and is solid. Questions just ask!
