The Buick castings for the 71-74 455's are the larger castings.  Edelbrock used the larger castings from the early 80's Chevrolet Truck engines to make their "850" cfm RPM q-jets.  They were nothing more than recalibrated standard units.  Your Buick 455 carb will flow as much as, if not slightly more than the Edelbrock 850 unit.....Cliff

I recently set up a Buick casting for use in FAST.  The engine dyno'd at 668hp and runs mid-10's on bias ply street tires!......Cliff
