i can tell you now , that i would have already ditched the 625 for a holley 750 DP. and i would have already installed an electric pump regulated at 6 . i think you are just plain running out of carburetor AND fuel pressure. thats my opinion
You're probably right but I have 2.76 gears (and 904 trans with 2600-stall converter) and do a lot of cruising so the Carter helps save gas and it's what I had from my old engine. I may try a Holley at some point and maybe upgrade the fuel pump after I make sure the lines, pickup etc. are good. But not an electric one, those drive me nuts with the noise!
