Bart- You're right in assuming that if you use high compression, low gears , and a high stall converter that you wont notice much loss of bottom end. It will go right past the lower rpms and get up there where the Torker is making power.

I tested the T1 and the T2 but I guess it was also like slowbirds test apples and oranges since the T1 was ported to match the heads and the T2 was unported and it was done on two different weekends with different weather conditions. The test was done on a 400 with same carb same jets, it ran 7.271 at 94.65 and 60' was 1.604 with a density altitude of 3982'. The T2 ran 7.404 at 92.93 and 60' was 1.661 with a density altitude of 2676'. Since the density altitude was lower when the T2 was tested that means that the T2 was even slower by more than the actual test shows. According to my ET prediction computer in the same weather it slowed another .183 seconds for a total loss of .316 seconds. I can usually run the ET prediction and take it off the trailer and run within a hundredth of a second of what it predicts so I wouild say it is pretty accurate.

The next weekend I put the T1 back on and advanced the cam 3 degrees and it ran 7.082 at 95.99 and 60' was 1.531 with a density altitude of 2651'. Advancing the cam helped a tremendous amount.

Soooo, Im not positive if the difference was the T1 vs the T2 or it was the porting of the T1 compared to the nonporting of the T2. But there was a definte difference at the track between the two intakes and of the advancing of the cam. [img]/infopop/emoticons/icon_biggrin.gif[/img]
