what carb would you put on this set up?

Actaully, if you run a too small carb like a 600 on a big enough engine or one that pulls high vacuum at idle, it can pull the secondaries open far enough to affect the Idle.

Good info, I hadn't thought of that.
:OT: How far of a drive is it to Houston for you? Check out www.theclashofthetitans.com, Baytown, July 16th. They had a race in Belle Rose, I think they only did it one season, though. I'll be there racing in the 12 second true street.

Interesting follow up here. I called to Barry Grant and talked to a tech there. He too has a 351W but with a slightly better build (AFRs on his while I have RPM Performers) and an auto tranny as well. He told me that BG's empirical testing reveals that the W runs better on a smaller carb. He tested a 750 and a 650 on his own 351W and his car made more power on the dyno with the smaller carb AND did better on the 1/4 mile to boot. He suggested a 650 with mechanical secondaries.
