That'* in the range I was thinking. I am going to guess about 15-25 higher on the torque number.

More than that!!! I ran 209.4 stock. I'll guess 244. Didn't you do a total rebuild?

Rebuild starts on the 7th (can't wait to get started!!!!!). Right now the only mods that would affect the dyno that I have are 3" very high flow exhaust, 2.5 SC pulley, Denso plugs, MSD wires and coil packs, CAI, 200 amp alt (negative effect?). The full rebuild is what I am going to compare to this dyno run later on down the road. See how worth the rebuild was then. Besides, the guy at the shop said he might be able to get me a discount on the dyno time because of how long it is taking to get the new exhaust tips installed on my truck.

rated 225, assuming around 30 HP loss (drivetrain loss is NOT a constant percentage) with mods, i'd say right around 225-230. Torque maybe 280-290? 3" exhaust will help some, especially with how straight it is.

Tomorrow when I pick up my truck I am going to set the date. And as far as a "straight exhaust"...

Here is about as straight as you'll find on a Bonneville...
