A secondary impact to this is when in first gear over a certian RPM (6XXX +, each one is different) the second gear clutches will start to drag, and when they are rotating in the opposite direction it has a tendancy to kill ET.
With all that being said, the reverse rotation, the stop, and the sudden forward acceleration of second gear could have negative consequences to the durability of a T350 trans it is consistantly over-reved. However most racers I know use 1st gear only to get the car moving and shift to 2nd very early.
It has also been our experience that shifting 1-2 early does not negatively affect ET to the same extend shifting late does.
I hope I got that all right.

Does the metric 200 function different? Any 8 inch converter weights?
