I agree with Dave Casey's findings and I will be the first to admit I know nothing about the Ford engines power band, or how it effects performance when switching from the 4 speed to the 5 speed, but I do know about the LT1 Chevrolets' abilities in these very same areas.

Probably few remember but Merc and I ran a 94 Camaro LT1 powered car in 1999 and 2000 which Woodro did the engines for and was the D/S NHRA National Record Holder @ 10.52 which was pretty quick in it's day. For what it is worth this car never ran as quick with the 5 speed as it did the 4 speed. On the best days it was a wash and most of the time the 4 speed was a couple hundreths quicker, so unless there has been some startling new developments in this area lately (like a higher/wider rpm power band) I think the data we achieved in this application is fairly factual.

In fact I still have a like new G Force 5 speed available with a 3:16 low and a 3:25 low gear set complete with a Long Shifter and the correct driveshaft for a late model Camaro if anyone out there is interested.
