Don't know that the 427SR/TW warrants that big a carb. If it's for drag use maybe, but street I would think not. I have the same motor in my SPF GT40. I do track days with it. Swapped the Holley 770 vacuum carb out for a Quick Fuel 750 mechanical. With a wideband A/F meter it is pretty easy to dial in jetting. Also the Quick Fuel allows a lot more adjustability than the Holley. The gas mileage is actually about the same as the Holley vacuum.
