I know this is an old thread, but bump. What size jets are you guys running on a 1/2 bridge or full bridged 12a w/ a 600 cfm??

I am currently running 58s in the primaries and 60s in the secondaries, but the car is still running rich

So are you running a 600 DP or a 600 Vaccum secondary carb? Why do you think it's running rich? Because it smokes or because the plugs are black?

Sorry for the late reply, but yes, the plugs are pretty black, full of carbon.... I actually just dynoed the car and w/ a 3rd gear pull it made 151hp and 102 ft/tq. The a/f were 13:1

Doesn't this seem a little low?? BTW, I have NOOO idea where my timing is, prob should get on that
