Results are in!!!!!!

292rw/290tq - 2nd gear pull

Dynoed on 265/70/17s (31.6" tall). Truck still has a fan clutch. E-fans are next.

Numbers seem low, but there is some more room in it once we get E-Fans & an UD Pulley on it. I'm happy with the improvement. Most stock "fan clutch" trucks are seeing 205-215rw.

Truck is still seeing around 16mph city & 21mpg highway, even with a heavy foot. Drives very well and has great street manners. Could use some more gear, (stock 3.42s), and some more converter would really finish it off nicely.

Next plan is to get it back to the track and see what it picked up there!!

That's why you need to get a similar bone stock setup on the same dyno. My truck put a solid 240 rwhp on a mustang dyno. On a dyno jet it put around 250 at the wheels. Bone stock. 119xxx miles only had a k&n factory replacement element. 265/70/R16 tires with the corrected gm calibration for the tires.
