I'd go with the Holley SystemMax II intake manifold , can't go wrong with it!!

You may want to upgrade to 30lb injectors to avoid the problem I ran into !!

+1 I'm in the process of looking for just the Upper RPM II, I'm running the Performer which use the same base as the RPM II
Have you checked Summt? I thought for sure they would have it. Or you could call or email Edelbrock themselves. I'm sure you've already done this tho.

Not trying to be weird but what are you doing with the gt40 intake after?

Is your problem with hot starting or cold starting? I ask because this changes the posibility of what the problem is.

A TFS intake is an optimum choice for your TFS heads. Should you ever decide to port your heads the TFS intake can be easily ported to match maximizing your power. The Holley Systemax is a great intake but is a better match for TFS HighPort heads. A match ported Edelbrock Performer 2 would be a good choice if your heads are already ported.

The StreetHeat or TrackHeat heads that have the same casting as the Twisted Wedge heads with the TrackHeats just having no smog provisions and higher lift capable springs are the heads your running? If this is the case and you ARE running TrackHeat Heads the size of your TB is the determining factor in which you should run, the TFS Street or Track intake. The TFS Street and Track Heat intakes have the same lower but the Track verson has a bigger upper and handles a larger TB and will maxmize your top end rpm track power. If your heads are actually Twisted Wedges the Street Heat Intake is the best you can run due to the heads smog provisions.

Advice: Look to foxlakeracing for your porting needs.
