HSAB 33 both ends
Idle Fuel Restrictors were .037 both ends - fixed by drilling to .040"

Trans is a TKO600 with .64OD

The throttle response across all ranges is much better than the Holley 750. The power comes one at a lower rpm because the secondaries come open immediately. Tire spin is much easier; like that was a problem.

No report on gas mileage. Double pumpers are notorious for poor mileage.
