It's an SD-455 clone made from a standard 1974 Firebird 750cfm.
With enough time/funds I suppose we could restore anything? Problem is, the standard 1974 unit is a $35 core (or less), and there are PLENTY of them available.
For dyno runs I'd recomend running it straight off the jets, this will provide the cleanest fuel curve.
I would also machine a complete set of secondary rods from the same cores. Swapping around secondary metering rods on the dyno will have fuel curves all over the place unless the same hanger is used and all of the metering rods have the same taper, tip length, and included angle between the tapered section and the tip(s).....FWIW.....Cliff
