Default "Low Blow" 2000 GMC RCSB

Finally got the project truck started over the past few weekends. Must thank Ron Mowen and all the great folks at Vengeance Racing for helping me out with this project!

I found this one-owner 2000 RCSB GMC Sierra SLE last year in great shape. It has some minor wear and tear on the outside as you would expect from a truck. But the owner kept the truck parked under a carport, so the interior was really nice and the truck was optioned well for a regular cab.

This project will be in stages due to budget limitations. This is the initial stage which includes:
  • LS3 416cid Stroker (ERL) at 9.9:1 Compression
  • RPM 4L80E Stage 5 Transmission
  • All accompanying parts to complete the install

These are the parts or items I have addressed as of this posting:
  • LS3 416cid Stroker built by ERL
  • GMPP Ported LS3 Heads
  • BTR Valve Springs with tool steel retainers
  • Vengeance Racing Kaotik Camshaft (235/243 .621/.624 113 LSA)
  • GM LS3 Intake (purchased used)
  • FIC 1000cc LS3 style injectors
  • Holley LS3 Fuel Rail Kit
  • Aeromotive FPR and Fragola Lines and Fittings (truck was already return style)
  • Trick Flow 4-Port Steam Vent Kit
  • Nick Williams 92mm Throttle Body
  • RPM Transmission Stage 5 4L80E Trans
  • FTI 3200 Stall, 10-inch, Triple Disc Billet Lock-Up Converter (PMLX4)
  • Texas Speed Truck Long Tubes and Y-Pipe
  • Custom 4L80 Cross Member
  • TCI Flexplate
  • ATI Balancer
  • Numerous small parts to make everything work

Here are some photos to date. I am guessing I have another 8-10 hours of work to get it running and on the dyno at Vengeance.













Following stages will be:
  • 12-Bolt or 9-inch rear end
  • Ridetech Stage 2 Air Suspension or Coil Over Package (either with 4-link)
  • Mini-Tubbing in rear for large, meaty tires
  • 18x12 rear wheel/tire setup for street use and occasional strip use
  • Nice Procharger or possibly turbo system finally (with fuel upgrades)

Made lots of progress over the weekend. Getting close to firing it up and tuning. Just a couple things left (wiring related).



Had to relocate the MAP sensor to the rear of the intake. Simply used a pipe plug to fill the front hole. This was required due to the cable operated throttle body. As the cam pivots the cables would crash into the MAP sensor and wiring.



Daniel (one of our fabricators) helped me out with making a throttle cable bracket. I tried the universal one from Scoggin Dickey but again cable travel issues. We ended up using the stock truck bracket. Made a few cuts and added a little pedestal to give us some clearance. Bolts right into place using the two front intake bolts.





Also have to address the y-pipe again after mounting the shifter bracket to the 4L80. Fairly easily fixed with just a small bend added in.



Mounted the trans cooler up front and ran all the -6an lines incorporating the factory trans cooler as well.



Got the F-Body fans mounted up with an aluminum hold-down and wired using the Nelson wiring harness.



Just need to finish up coil mounting and make plug wires, then add fluids. Also want to clean up the harness. Can't have all that on top of the engine.

Looks dope! What do you think it will make for power in it's current iteration?
