BTW: Both those carbs, although pricey, are beautiful.

Yeah a 750 would be way too much carb for this engine combo. Going by the formulas that most use, a 650 or 670 is even a little bit too big.

I guess my biggest question is whether a vacuum secondary or mechanical secondary would be better for a street driven truck. Holley says that the Double Pumper is more for a lightweight car with a high stall. So that has me leaning more toward the Avenger(or other vacuum secondary) carb. Is there any reason to go with a mechanical secondary carb over a vacuum?
