Hey all,
Pretty much as the title states. Right now i have the weber on a stock port 12a with a lake cities manifold. I am getting a 1/2 pridgeport motor, bridged on the primaries and streetported on the secondaries. What i need to know is the weber works real well right now on the stock port motor, but i am figuring i am going to have to do some rejetting for the new motor. Anyone have any suggestions?
Thanks,
Bryan

 

I found this in an old post about a 1/2 bridgeport....any thoughts?

Your settings on 12A streetport/bridgeport

38mm Venturies
160 Air correction jets
200 Main Jets
f16 e Tubes
f9 65 idle jets
0 Bypass.

 

My guess is the 45 will be too small and you will need to upgrade to a 48 mm Weber. All my reading tells me that my Mikuni 48 PHH is to small for my 1/2 bp but the Weber 48 isn't. Still haven't had much of a chance to do any wideband tuning on it yet to find out for certain.
