I have a pair of Quick Fuel Technologies billet aluminum 1050 cfm E-85 carburetors. These have boost referenced primary power valves (can be used on N/A motor by just capping the small ports.
These are 4150 style....NOT dominators. They are in PERFECT condition, they currently cost $980.00 each new! Priced at $1,200 for the pair INCLUDING shipping anywhere in the lower 48 states. Jocko
