Sounds like a Pontiac RAIV Quadrajet Factory orginal dialed in perfect this Video demonstrates of a Holley Dominator 1050 on a 454 Chevy.
The induction noises near identical.
My BLP 1085 cfm 4150 Annular Booster DP Has a different sound Revving up and driving.
Heavy loads 3rd high direct in the TH400 It kinda growls, can hear over the open exhaust no mufflers Dual 2-1/2" inch pipes.
The Dominator 1050 Makes wonderful noises I recall Pontiac only Factory Carburetors but way more CFM.
