Everyone says to "upgrade" to a TH400 or PG once you get over 1000 HP. Other than the obvious things like the availability of aftermarket SFI cases like the Reid, what makes the GM units better?
Brad Watt (A93demon) still runs a 727 in his demon. He has been in the 4's at 3200? lbs so i would say he making over 1000. He does leave in second gear so that solves the gear issue , 727 is just as strong as a th400 , but the aftermarket for the th400 is way better, thats really all it is
