GT-40 or Cobra Intake? and...

I like the gt40 intake because of the lbs. it saves, but for more room to grow the cobra because you can port it larger, cast vs steel tubing, installed trickflow stage1cam. and heads last week runs good just bumped the idle 200 rpm

I am running a ported cobra intake and an E-303 cam with Canfield heads.

I like the cobra intake better for the reasons listed above. The E-cam sounds great but many cars have trouble with a surging idle.

I have to have my timing at 16 degrees, my TPS voltage at .98 and my fuel pressure at 38 psi with my 24# injectors or I get an idle surge.

After I got it all dialed in it has a nice choppy idle at 800 rpms.

My car makes over 300 RWHP and torque so I would say that the parts perform pretty well.
