This is a older build which I post here every year or two.

But, if anybody is interested in seeing the status/progress of a 900+ hp, ugly ***, long bed silverado sleeper, here is the full build documentation:

https://xtremeownage.com/index.php?t...e-racecar.323/

Current projects include:
1. Fabricating the rest of the dash, mounting gauges, lights.
2. Transmission is back from TCI, install will be done friday.
3. new catch can/pcv system.
4. Configuring the holley HP for boost control.
5. Installing a new rear-main seal.


To grab your attention, here is a data log I pulled from before I nuked the tranny.

Slamming gears at 7,300 rpms, under ~20psi. AFR stayed in the 11-11.7 range under boost.





The goal of this project, is mainly to have fun. The end state will be running low 10s in a ugly *** pickup truck, which nobody would suspect.

While, yes, I could drop this powertrain in a camaro, or fox body and run 9s.... it just seems funner to do it to a vehicle nobody would consider making fast.
