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.
