Which set would you guys recommend I go w? 451 big block DD w mild cam. more interested in mileage/driveability than HP potential.

I went to the site you sent & they want over $200 canadian for the rebushing kit & iirc it has 8 bushings. You and a local guy who does them said it is a rarity to have to do them but these are LOOSE but that's MY subjective assessment. I should grab a dial indicator & shoot you a dimention. he's going to do em for $25 a shaft so I might have him do all 4 shafts (anal I know but they SEEM too loose) and I want good mileage/driveability and dont want to have to go back inside again live every 24 hour block of time like it's your last day on earth

If egg shaped they are worn, if round they are probably fine. I rebush them all anyway so it's no matter to me. BTW, the EB is basically the same carb, however they did make a few design changes to the casting, one of the changes made makes the typical method of rebushing them impossible due to the length of the shaft/tube casting.

I know I bought a bunch of old AFB's to make hemi clones and one of them did not have an air door, can't remember if it was the 4131 or not. If no air door I wouldn't monkey with it. Sheldon
