I,d go with a Holley 650 or 750 with vacum secondaries.The 650 should be plenty and you,ll notice the difference!:read2:There,s books on Holley,s that you should read up on,it,s always good to know different jets,metering rods and tuning.If your gonna own one,it,s good to know how it works.2 centos
