what a difference off idle and any thing under 15 mph with AVS2 800cfm compared to the old 750 carbs. sometimes i would get the off idle stumble and less power with the old carb.
on all six cars 440 mopars and 425 buicks skylarks all kinds of intakes 7 different ones and about 10 different cams. some times if the stars all in line they would perform good, you forgot ignition timings which i also mess with. it also showed on the dyno where they go lean then get richer.Since you are talking about bottom end we need to know these things that are related to it:
What cubic inch is the engine?
what intake manifold?
stock cam, or bigger?
what rear end gears?
what size rear tires?
i did say 440 engines and i never asked a question i was just saying what happen with me. i was keeping it basic i had to many combination over my 47 years to list. am sure the 750 would be more suited to a basic stock engine.I didn’t forget anything, I was keeping it short and simple, just the basics.
You know, all the stuff you forgot To mention. How can we answer your question?
stock 318 with 276 gears?
stroker 440 with 456 gears?
The answer changes quite a bit.
