I think any carb bigger than stock will give you more power,, up to a point.
A 2 bbl carb would probably better suite your stock 230 CI engine for the time being.
The Holley 390 will work also. Depends on what you are looking to get out of it.
Better mileage,better power.
If it was my truck, I would use the Holley 2 BBl or Langdons 2 barrel for better mileage.
If it was a 250 with a little more mods done to the engine,a nicely prepped Quadrajet.
For all out power from a carb or carbs,, sidedraft Webers DCOE's
Very streetable & provides a lot more torque. Pricey though $$$!!
