My 94 GT with Trick Flow Twisted Wedge heads and stage 1 TF cam seems to have out grown the TF Street Heat manifold that I had on it before. The heads are in the process of getting a 5 angle valve job on them. So I want to buy a manifold that is more suited for these heads while the car is apart. But I also want something that will work when I get a 331 to replace my stock 302 in 1 or 2 years. Am I correct in thinking that the Street Heat is a bottleneck in my combo, if so which manifold would you guys suggest? I'm guessing the Holley Systemax would be too much for my combo and I'm not too familiar with the other options. Maybe just go to the TF Track Heat? Any opinions? Thanks.

Chris


quick list of mods:
TF heads, TF stage 1 cam, 1.6 rr's, LT headers, 65mm TB, 80mm MAF, 3.73's

If the TFS manifolds work like the Edels

Just get a new upper to have the Track Heat

Is the car a street car? I'm assuming so with such a mild camshaft.

With that cam, the car is running out of steam somewhere between 5800-6100 RPM. The manifold you have on there now works perfectly fine in that RPM range without losing any low-end power.

Leave the upper that you have on there now and just buy the new upper when it comes time for the 331 (get a 347 *cough*). What's the difference whether you buy the Track Heat upper now or later?

Listen to this peckerhead, he knows what he's talking about

Keep what you have now. Then buy the proper manifold to support your 347 in 1 or 2 years. If you want to change the manifold now, swap in a cam to make the package all work. A track heat upper swap won't do much if anything right now.

Fwiw, I went 12.80 @ 107 with that combo a few years ago. I'd say your main bottleneck now is the 3.73 gears. 4.10's would help out a bit. Probably give you another 2 mph.

Tuning, weight reduction and gears would be a smart move.
