Alright.. The lifters are set and she purrs like a kitten. I knew I was running rich but after hooking up the wideband today it turns out I'm running 13ish at idle with the mix screws almost all the way in and as soon as I tap the gas I go as rich as 8-10. Revving the engine brings it down from 13 to 8 every time. I get lots of dark blue smoke too. But she sure does drive nice.

The carb is a rebuilt (by me) Holley 600cfm 4776 DP - Primary main jets 65, Secondary main jets 75, Power valve 6.5, Primary Nozzle 31, Secondary Nozzle 32.

I need to be able to drive it a ways to get it to the in laws where I'll mount the turbo.

I'm pretty sure it's going to be jet sizes, so I'm hoping some carb guru could make a educated guess on a jet size to get me to around 14 when cruising. Also, is there a trick to lean out the idle more than the idle screws allow?

I was thinking of getting 58's for primaries and putting the 65's for secondaries... that sound good or should I go lower?
