whats the difference between the edlbrock air gap manifold and the performer eps???? besides the obvious gap for the air. which is a better manifold for performance. i got a 650 carb. and a stock cam. which im gunna change to a mild one. just curious cause the air gap thing is def. really cool . and i want as much as possible outta my car

 

the part numbers on summit are edl-2601
and edl- 2701 if that helps :-D

 

The main difference is the air gap under the carb. The air gap prevents the carb and intake runners from heating up as much. (it's also a little straighter shot to the intake port...Cooler air is denser air, therefore more air and fuel = more power. However there is a down side to this...air gaps aren't all that good with a cold engine in cold weather. When the manifold is very cold the fuel canpuddle and you may have drivability problems.

I like the performer rpm, but it and the air gap are tall so there could be clearance problems.....

Also the cam you select will effect which manifold works the best...
