Edelbrock Performer RPM

Yea man! What he said.

The air gap is nice and worth a few more ponies over a regular rpm due to the lack of heat but also keep in mind that the intake will have your car throwing fits in the cold with the choke constantly coming back on and long periods of warm up.

If it is a warm weather car onky, no worries.
The LD-340 is capable. The large runners move a lot of air.

If your car is doing this to you something is wrong.

Mine doesn't have a choke and this isn't an issue.

I agree with rocco on this one. I know "New York cold" and "California cold" are pretty different, don't get me wrong. But I have plenty of below freezing starts on the Eddy air gap on my my 340, never had any issues with it. It fires immediately on the first crank, dies before the electric choke kicks in, and runs 99.9% of the time right off the 2nd crank. That's with a street avenger carb with an electric choke.

But yeah, I'm talking less than 32*F and usually more than about 28*F, it usually isn't colder than that here when I'm trying to go to work. So, if you're talking less than 28*F, my comments may not apply.
