New build for my Wife's 2003 Tahoe

[Boosted Hoe]

Details on the build:

Details on build. Well I have finally completed the new engine for Judi’s Tahoe. It’s a .030” over LQ9 (370ci) with Mahle forged flat tops on Gen 4 rods with ARP Bolts. The Cam is from Cammotion with 220/234 duration at .050” and .585 lift (smallest PD Supercharger specific grind) using HyLift Johnson LS7 lifters and Smith Brothers 7.425” .080” wall pushrods. The heads are TSP ported 317 castings with PAC 1219 Beehives and Ferrara stainless valves using REM polished OEM rockers with the solid bushing upgrade. With the Kooks 1 7/8” Longtube headers, this 10.1 long block should make about 500hp NA. I may have to dial the Magnason TVS1900 down a bit from the 12psi it is set up for on the stock 5.3. No need to be crazy. I built this as a 200,000 mile replacement engine for Judi’s Tahoe, so almost zero used parts were reused. Don’t let anyone tell you building an LS engine is any less expensive than any other. Unless you want to use a bunch of used or junk Chinese parts.
