I

just returned from having the truck dyno'ed at Speedcraft in Orange Park Fl.   335.9 ft lb of torque at 3000 RPM and 261.8 rwhp at 4200 RPM. The torque stayed above 320 ft lbs from 3000 - 5200 RPM. Using the accepted formula of torque x rpm/ 5252= HP I get 320x5200/5252=316rwhp. The air/fuel ratio showed it was running a little lean. I have a adjustable fuel pressure regulator to install.

Nice truck, haven't seen an L-98 conversion on a newer truck like that.  Seems to have worked out well.

Thanks for the comments. It has been an interesting project, and fun to drive too. I have learned many things about computer controlled GM vehicles.

I have tried to focus on reliability first, and power second. That strategy has paid off. The truck is driven every day and the last tank of gas I got 15 mpg.
