Dyno is done HD117kit 10.7 Suburban speed pistons, Tman 590 cam and Suburban speed head job porting polishing and oversized intake valve. It pulled from 100TQ at 2500 RPM up to 133TQ at about 4700 RPM and maxed out at 124HP at 5500RPM but holds it till 6000RPM. My exhaust Vance and Hines OS450 rounds and power dual header, hurt my low end a little, but I love the sound and 100TQ at 2500 RPM is not to shaby LOL. Dyno was a Dynomite and the tuner said it usually reads a few HP and TQ lower then the local Dyno jet dyno's. I can't wait for nice weather so I can feel the power!! LOL.
