Carb numbers

[b52rule]

I may have found a Quadrajet.

Do part numbers 32747 and 36021 work for us?

There are a HUGE amount of Q-jet carbs out there with different numbers. The cubic inch numbers doesn't play into the criteria of enter change ability as much as you may think. Thus a Chevy 454 carb,and an Olds 455 Q-jet aren't the same. Cam, distributor, carb porting, expected RPM, and load range, shift points, gear ratios, and on. The carb numbers are extremely important It comes down to works or works correctly. Bob Dunahugh
