I'm installing the raybestos Kit on a six speed, and I was sent the wrong Lock up valve. I was thinking on modifying the stock valve for zero knockdown anyway, my question is since I'm building this trans for around 650hp and below (no billet c2 hub, or p2 planetary, stock shafts) would zero knockdown be anymore beneficial than the A1-Lu-bst-04 transgo valve? If there is no real benefit at the power level this trans will see I'll just get suncoast to send me the correct valve. I was sent the early style stator valve A1-Lu-bst.

Cut 20 to 30% off your heart rate and go run a mile and tell me if you feel a difference.
