Intake swap?
 

I have an 89 LX 5 SPD. It has a hot cam, shorty headers, MSD ignition, 70mm thottle with a spacer. All of the smog junk is removed. The heads have been ported, polished, with a 3angle valve job done on them. Will a cobra upper and lower intake add anything over my stock intake? Is there any diffence in porting or flow with the cobra intake? Simply put, is it worth the time?:confused:

With your mods you would pick up quite a bit of power going to a cobra intake. Porting the lower of the cobra intake is a good idea.

I put over 300 to the wheels with a cobra intake.

If your handy with carbide bits and have the equipment, you can get a stock intake to flow 200cfm - my website has instructions on how to do it and many tech articles on the dyno and track results of doing it. For E7 heads (even ported if they flow ~200cfm), the ported stock intake will make more average power over the idle-6,250rpm band than the Cobra, although it is the next best choice. No need to port a Cobra for stock E7 heads, but your heads may benefit from it as they have been ported.

Thanks for all the info guys, I am thinking I might go ahead with a cobra intake set up....... :)

Make sure it's not an ebay knockoff, seen a few of those floating around.
