Review on 🔧 Holley 37-474 Carb Repair Kit: Comprehensive Solution for Carburetor Issues by James Trapkin

Apparently he had parts for all variations of this carburetor (optional). I have a Holley dual feed, dual pump, manual choke. Turns out that's too much for a 4.3 Vortec with an automatic transmission in a Mazda pup, so I'm going to replace it with a Quadrajet. That means it's for sale! Instructions only but I've rebuilt more than one carburetor since '66 so take this as a no-brainer based on your experience and/or help available.
