1976 D100, A833OD, 318 w/ headers & Edelbrock performer 2176 intake. Cam is unknown, likely stock. If not, something near stock. Currently has the Carter TQ 9250S that was on it when I acquired the pickup a couple of years ago. And it is shot. Wiggle the primary throttle shaft and get a whistle. Although I'm a fan of the TQ's I've decided staying with one is too much hassle for this application. Going back to a 500 CFM 2 barrel might be best but that would require buying an intake and a carb. At new prices that's approaching EFI throttle body injection like fitech, Holley, etc. So for this reason I am hoping to find a small 4-barrel (600-650 cfm) that fits the intake, is dependable, and pretty much a bolt on and go.
Looking at Eldelbrock Performers 1406, AVS2, Demon 1900 or 1901. Others? Thanks in advance for all tips and recommendations.
IMO, a spreadbore carb (Thermoquad, Quadrajet, Holley 4175) would be the best option for your truck.
Years ago, I had a 1985 Dodge D150 with the 318 2bbl. I removed the stock 2bbl intake & carb and installed a used Edelbrock Performer 2176 intake and rebuilt Rochester Quadrajet from a late 1980s Dodge Truck 360 V8.
It was the best mod I ever did to my truck. More power. Fuel economy and drivability improved. The truck would start instantly - hot, warm, cold - almost like EFI.
I personally prefer the Quadrajet over the Thermoquad for reliability and performance. The Q-Jet was installed on 1985 to 1988 Dodge Trucks & B-Vans with the 360 V8 from the factory.
A rebuilt Thermoquad would be the easiest option for you (if you can find a good one). Scott Smith at Harms Auto rebuilds TQs.
https://www.harmsauto.com/The Holley 4175 spreadbore is a nice carb but is very expensive.
https://www.holley.com/products/fue...ors/emissions_replacement/parts/0-80555CAn Edelbrock Performer, Edelbrock AVS2, Holley 4160 or Holley Street Demon carb in the 500-600 cfm range would be a good choice as well (and they are easier to find).
Note: You will need a squarebore to spreadbore adapter to mount these carbs on your Edelbrock Performer 2176 intake.
The Street Demon is designed to fit both intake styles so the OP will not need an adapter. Another cool feature unique to them.

I don't have experience with either carb but these are the two I would look at.
Hope this helps. Good luck.
