Most dual planes work best from low-rpm to mid.
Single-planes usually cover the top, by giving up some torque at low rpm.
The AG is touted as a full range intake, and has proven it's worth
But it is the cam, for the most part, that determines the operating rpm of the engine. So if you have a stock cam, The AG won't do a lot for you, that the factory intake can't.
The only way I would put an AG on a stock engine is if it was the only 4bbl intake I already owned.
Gearing makes it worse.
If you have 3.23s and 28" tall tires, and a stock 4bbl cam, top of first gear might be 5500@52 mph. On the 1-2 shift, the Rs will drop to 3250, and this gear will hit 65=3650, and won't get into the meat of the AG until say 4500@73 mph.... but the cam is done at about 5000@81mph.
Can you see how the AG is out of it's best zone most of the time.... whereas the stock one is in it's best zone all the time.
In first gear;
if the tires spin, it don't matter what intake is on it, cuz yur only gonna be in first for about 3 or maybe 4 seconds.
But if the tires don't spin, the AG is too much intake anyway.
I suggest;
to put your money into a good hi-stall TC, instead; you will be way further up the performance curve. And after that, get you some more serious gears..... Once your tires spin up no problem, and they stay spinning, you'll forget all about the AG.
But if your engine is not a stock 4bbl engine, well then, all this goes right out the window.
