power shifting is way easier on gears and drivetrain. what gear do you do burnout in? 2nd or 3rd? the soft loc clutch is best set up. you adjust the base from the back side. where trans bolts up. on mopar trans , I used upper right bolt hole to get to adjusters. on a jerico, requires a hole drilled in back of housing, you can do that in a drill press. power shifting into 3rd doesn't hurt it. comes down to release of clutch and shifter adjustment. I've ran stick cars for last 50 years, they were stockers.
