If you really want poor throttle response on the bottom end, on vehicles
with tall final drive ratios, ( like 3:07 - 1 ) then just bolt on a big 'ol
Holley double pumper. It will fall right on it's nose. Same thing with a
big Quadrajet, or Carter AFB.
What you ARE after, is velocity in the inlet tract. This will promote
throttle response. This requires smaller, not larger primaries.
It was the reason for tri-power instead of one great big carb.
Don't have enough room on the net to explain further, but trust me on
this one. If you want a more in-depth explanation, catch me at a rally
sometime and we will add it to the bull session.
Bigger ain't better, no matter what your car guy buddies say.
