Ohh and its a very good mod the UD Pulley. unless you like burning up alternators and power steering pumps at 6000+rpm shift. and its required to have an SFI Damper if the motor spins past 6500 rpm also. they Dont check for it or ask in tech at NED but i have gotten asked at Atco.
What mods do you have Midnight? And I don't see him going past 6500 in any meaningful way if he has stock internals. I'm just saying from experience ( I had an SLP pulley for a little while) for the ridiculous money you are going to pay for one you get next to nothing. You would see more on a SBC or an LT1. I shifted at 6750 and never had a problem with an alternator or PS pump or slipping belts.

Back on topic, Midnight, I'd be looking into suspension mods if they haven;t been done since most underdrive pulleys are at least halfway to the price of a torque arm (SFI rated one probably cost more than a torque arm). That is if you actually want to go faster and not just make 2 more RWH on the dyno.
