One possible issue is the carbs are not staged. In most cases one has to be delayed from the other depending on the configuration of the intake manifold.
Another possible issue could be not enough accel pump travel or too late. Not enough fuel coming thru the accel pump circuit on one or both carbs.
Either way, its probably too much air and not enough fuel in the mix.

Testimonial: "Thank you. I have been trying to mess with the air and fuel mixture. The staged part I am not sure on how to check that out. Every time we mess with the carberators we adjust both of them. I am thinking about taking them off and put them on a car one at a time to get them them just right."

SOURCE: Engine stalls when stepping on gas pedal and will not idle on its own.

Have you checked the ignition timing? Maybe you need to turn the distributor to the left or right if you don't have the timing light gun

SOURCE: The fuel gauge doesn't read right, makin' low fuel light flash

if the fuel pump is all in-tank; the sending unit built in to the fuel pump is most likely malfunctioning; if so, this will require removal and replacement of the entire fuel pump, sometimes expensive, others not so much

I bought a Camaro with a 383 crate motor. it has HOLLY aluminum heads. The engine identification number on the block is VO327TMM. Can anyone tell me about this motor? I no its a crate motor, thats it.


No because I don't know what camshaft is in it or what intake modes/exhaust and so on. The block number means nothing as far as HP goes, it is what goes into the block and on it that matters.
