vac carb jetting?

#1 Post by jaspermaggie » Sat May 02, 2009 9:50 pm

I have a holley 750 vac carb and had it jetted 75/76 at wide open I was at 12.7 a/f pretty much all the time. I would like 12.8 at wot and less just cruising around. I was thiniking 72 in front would be perfect. What do you think I should use in the back 78? My thought was if I went down 3 I should go up 2 but I don't know if a vac is the same as a dp.
My car is not as fast as I think it is.
