Hey guys junk the Holley or make it into a boat anchor. I have found just the thing. R.V. Morse in California does a complete flow job on 4.3 TBI's. The flowed TBI with regulator and guage built in sells for $60.00 less than the Holley.He gets 10 to 15 % better flow than a stock 4.3 and it comes back just as pretty as the Holley.JMHO

P.S I can give the phone # to anyone interested.
