Go with a Quadra jet or a Holley 750 vacuum secondary model 3310.

Yes that was what I planned, but is there no problem with a vakuum on a 4 speed?. Thoth it maybe wod give a bumpy ride on accselaretion? This is my first built with a 4 speed, wood like too get it right the first time. :-) Thanks Jack.

Vacuum has nothing to do with the transmission - it has to do with the engine, and specifically with the camshaft.

Jack, what do you plan to be your max engine rpm.  A 650 cfm carb will work if economy is what you are after.
