My dad and I are both running 23 spline stock transmissions.
His is more impressive.....3900lbs!!!! mid 11's on slicks.
NEVER BROKE A SINGLE TRANS PART IN 40 YEARS. Power shifting every run. Now this is a true street car that is beat on at the track about 20-30 runs a year. Probably around 550hp
Mine is about 525 hp and 3300lbs but I haven't been to the track yet with this setup.,,,but it ran 11.07 in Oct with an automatic.
