Tell ya what Billy, I've actually had better performance with a 302 using the stock Autolite 2 barrel that came on the car.... The Holley two barrels work great for me---running on a circle burner at WOT all the time, even then they like to stumble and bumble all over themselves if you have to feather things a bit in our out of a corner..... JMO.

Wish I would have kept the part number, there was a vacuum switch that we used on the throttle linkage to hold the throttle open slightly when you first stopped, until the vacuum went up again and pulled the switch off... Might want to ask Mike P.---might have been off the tri-power Holley setup for MoPars????? Anyway, mounted on a bracket that attached to the left front carb stud... real similar to the electrical A/C idle up electric switch...... I'll look in the shop for you Billy, might have one of the switches or a part number left over out there from my circle burnin' days.....

As for the new carb and manifold, keep your eyes open at the salvage yard, the factory 4 barrel intake for a sbf isn't all that rare...buddy picked one up the other day for scrap weight price! Let me do some diggin' around in the corners and see what I have for leftovers that might help you out......
