I asked MBRP about their expected delivery date:

" Completion date........... this is a tough one. This project was originally to be ready for the summer shows, it will not see this summer now as all the "one off" parts have taken so long to design and build with many still to go. We are likely looking at fall, this year before we get any road testing done."

For those who want to know a little bit about MBRP.

For over fifteen years MBRP inc. has been delivering performance enthusiasts the most in power, the most in product quality and the most in customer responsiveness. It all began with the now famous B&B Eliminator, which soon achieved the status as the best selling performance snowmobile silencer of all time. Starting from little more than a vision and an absolute passion for all things performance MBRP inc. is now at the forefront of performance exhaust technology. Marshalling over ten decades of manufacturing and marketing expertise between them, the MBRP design team developed a line of performance diesel exhaust products that has made the rest of the industry take notice, and rush to catch up.

Most recently MBRP Inc. has achieved something special for the sports truck enthusiast. The new sport line brings to the gasoline-powered vehicle the same perfect blend of style and toughness that diesel light truck owners have come to expect from MBRP. The line features a unique flow through muffler originally developed to increase the performance of thousand horsepower off shore marine engines. The result is a muffler that generates a deeper, mellow sound, improved performance numbers and cooler operating temperatures.

The central reason behind MBRP inc.'s remarkable growth has been its absolute dedication, not just to excellence in its products, but also to standing behind its distributors and dealers and the loyalty that they have given back in return.. This commitment has been demonstrated in many ways. A diesel line with the lowest SKU/ vehicles supported ratio means that warehouse distributors require lower standing inventory and enjoy faster product turnover. Offering all of its diesel and sport truck systems in aluminized, T-409 stainless and T-304 stainless ensures that dealers have a price point and product for every customer's need and pocketbook. Full bolt-on design and clear, well written instructions mean that jobbers can install most of MBRP's systems with minimal tools and in under forty-five minutes. And for everyone, toll free technical support that can talk even the least experienced installer through the process.

For the future, MBRP inc. is determined to provide the highest fill rates in the industry, offer the most complete line of exhaust for diesel and sports truck enthusiasts and to be always pushing upward the definition of performance.

That engine bay does look like it was meant for a v8... I think GM put the wrong engine in there..

And here is the update;

I got a list of internals that went into the LS7 for the Colorado project from EPP (Exotic Performance Plus)

With 22lbs of boost, this is what is needed to keep the motor bullet proof.

EPP is doing a fantastic job on the motor……they are a big name in the industry. Dustin Portmess is the guy that built the motor at EPP.

Diamond Pistons 11596
Compstar Connecting Rods
Clevite H series rod (CB663HN) and main bearing (CB2199HX)
ARP main and head studs Total seal rings with an AP steel top ring
Comp Cam duration @ .050 is 236/246 on a 114 lobe separation
installed @ 113 intake centerline with .637/.650 lift Manley 5/16 one piece pushrods The heads were O-ringed at West Coast Cylinder Heads Valve springs are comp cams 26921kt

The engine is 428.69 CID. The bore is 4.130, and it has the stock LS-7 4" stroke crankshaft. The compression ratio is 9.37:1 The block was honed with a torque plate, and the crankshaft was computer balanced to
1/4 ounce/inch.
