Way back when I used the Holley TQ replacement when my TQ bowl starred leaking.
Ij just wanted to have no problems so went to Jake's Speed Shop on New Orleans he sold me the Holley made for 1972 340 with manual secondary thzt was a bolt on.
Hooked right up to what linkages were there and ran well out the box.
It was run for years and was good without ever being a problem.
It did what it was supposed to do, and was a quick swap fix.

Put a,square bore I take Street Domanater as the car was. A street used commuter everyday and 4777 when I rebuit the whole motor.
