Ok , what 4barrel would you suggest? Am also looking at that Clifford dual setup again instead of a single carb- but I don't know. Am a member at OLDGMC and have a post there also....
As stated in my earlier post, I would suggest either the Carter 9400s or 9410s (both are 400 CFM); but if you like Holleys, the Holley 390 would be less initially. Final cost would depend on how much you drive; the Carter will probably get 25~40 percent better fuel economy than the Holley (I personally got more than 20 MPG AVERAGE over 400,000 miles on my 300 CID 6 in my shop truck.
