Reply to "What carbs are you using on your Cleveland motors?"

Thanks Guys,

I have what appears to be a 600CFM 4160 series vac secondary carb currently on the motor. Personally, I've never been a fan of 4160s on a manual trans car. I was actually looking at the 4150 model 80528 Holley Pro series, 750cfm w/ mechanical secondaries. Looks like PI sells it as well, but difficult to tell from their description whether (they) tune/jet it close by application or if it's an out of the box 80528. Hard to tell whether this carb has the large PB vacuum port. I see that the throttle bores are opened up an additional 16th". Anyone run one?

Perahaps a better starting point for my stock-ish rebuilt motor would be the 82751, also a 750 MS carb, 4-corner idle adjustment, standard 1 and 11/16" throttle bores, looks like it comes with 75/80 jets and 31/28 pump nozzles. The picture of it does reveil the large PB vacuum port. I've got a master jet kit on the shelf somewhere but haven't opened it in a while. Mike Ulrey did a masterful job (as always) on the restoration of the original Holley 780 (and distributor) on my BOSS car that required no further tuning, and Craig Conley did the modified Holley 700 DP on the Paxton/GT350. It too was dead-on.. Thanks all, comments/suggestions much appreciated.
