I've ran a bunch of different sixpaks on a lot of different motors, on your deal I would check the vacume idling with the motor warmed up in gear and then use a power valve one to two inches lower than that. The reason I'm suggesting that is I had a sixpak on my 518 C.i. low deck pump gas stroker motor with a big solid roller cam in it that I had a 2.5 power valve in the center carb., I swapped the motor out(reuse the same carbs on both motors) to a smaller 464 C.I. RB motor with a smaller hydraulic cam and found out that the 2.5 power valve would start to close and reopen in high gear in the 1/4 mile, NOT GOOD! I put either a 4.5 or a 5.5 ,(CRS)power valve in it and that cured the problem in high gear. IHTHs
