Anyhow, If you turbo stock 292 to 8 pounds of boost your power will increase to around 300 hp and over 300 pound feet of torque...a 261 is not the best motor for 1...parts are scarce...2 trying to find performance parts are nearly impossible. If you were going to do a 6 cylinder a 250 or 292 would be your best bet. Note that many parts aren't interchangeable between the two...a 292 crank will fit a 250..or a 250 head on a 292. The 292 will get much better rpm rang then your cummins will...I can rev my 292 to 4,500 rpm between shifts...and the bottom end is stock...but my carb and manifolds and ignition aren't. The 292 peaks torque around 1,600-2,000 rpm...and hp around 4,000 according to factory. Now if you do a 6bt 5.9 turbo cummins you'll put us all to shame! LOL!

A typical 292 gets 11 mpg loaded or not, wether its in a 1/2 ton pickup, or a single axle c60 dump truck.
