I have a 3310 holley 750 vac. sec. and just got the secondary metering block conversion kit that allows me to install jets in the secondary instead of the metering plate that came with carb. (406 smallblock, .485lift 284 deg cam,torker 2 intake, automatic)
I am running #72 jets in the front side and have it pretty well dialed in. My question is what will be a good starting point for the secondary jets?

The conversion block usually comes with #76 jets, did yours? That's a good place to get you going and then once it's running you can tune the jetting from there.

Thanks, not sure what it came with as I have not opened the package yet, I was thinking it would come without any, but I have lots of jets to play with. I will go with 76's and when spring rolls around I will take it out and play. (I'm in Mn so its parked for a few months)(
