I bought castings only on black friday 2020, with shipping was under $450 for the set. I had my engine builder put good components in them for another few hundred. I doubt the car would run any better with Edelbrocks for twice the money or more. Its a 360 with stock crank and rods with Icon pistons 10.5:1 compression in a 68 valiant that weighs 3350 lbs with me in it that runs 11.60's in full street trim and steel wheels.
