Default SD-455 Qjet Clone

Some people wanted me to post this Ebay special.

It's an SD-455 clone made from a standard 1974 Firebird 750cfm.

The real SD carb is an 800 with the larger primarys so the builder of this unit figured he'd hack out the outer booster ring to match the CFM and leave the rest of the calabration stock.

Bad idea as it kills signal strength and proper atomization and unlike the 71' 455HO single booster which the single booster extends down about 1" this one is only about 1/2" long

I'm currently modeling, fitting & making replacement outer booster rings to correct this unit and here's a few pics.
