Trans shield

I picked up a solid 2-3 10ths going from 727 to 904. Now, I changed from a aftermarket steel driveshaft to an aluminum one. 6-7 lbs right there. Then I went low gear set and bumped my flash from 3340 to 3500 rpm. So some of the gain is in there, but a 904 built well will live for a very long time behind something making much more power than I am. I broke a sprag in my 727. I was in staging and it took longer for it to drop into gear. I tried to get it to do it again and it wouldn’t. Felt weird in the burn out. Aborted the run, couldn’t get it to really act up, until I got it to pop while in low. Good enough for me! Rolled all the springs, cracked the case, broke a roller in half.
