2005 chevy 1500 came in for a little change. Pulled out the 250k mile 5.3 and dropped in a refreshed 6.0 with a few supporting goodies. Stage 3 GPI high lift cam, fully upgraded valvetrain, and combined with a 3200 billet stall in a 4l80. Pretty neat in a 4wd single cab shortbed.

Very appealing layout. 1967 Chevelle in for some much needed attention in the driveline, rebuilt 12 bolt with new Trac bars, disc brake conversion, new driveshaft to support the hot torque of the 502 and some other goodies. Transition into putting AC into her so customer can enjoy a nice summer.

2016 Chevy Silverado with 192k, AFM lifter failure a little late in life on cylinder 4 that was properly not ran for any length of time and still showed signs of scoring on the camshaft. Installed a DOD delete and all supporting replacement parts, back up and running good as new with plenty of life left to keep on racking up miles.

2015 Yukon XL with 172k with a well so common lifter failure on cylinder 1. Started to dig in for a camshaft and lifter replacement and found some damage and some history of possibly a prior lifter failure with metal damage, Sourced a new engine. And added some parts for this not to be a future issue. New motor mounts as well due to the internal oil leaking out of the mount absorber. Repaired quite a few undesired flaws with wiring and recent repairs. Back up and going without skipping a beat.

2013 GMC Sierra LC9 5.3 with some oil pressure weakness came in for some diag that turned into rowdy selection of build. Turned out to be a leaking cam retainer plate. Bottom end was in spec, new oil pump, lots of new parts, Gwatney Performance Innovation Camshaft, johnson lifters, new 3 bolt conversion timing set and cover. Hardened pushrods, and a stout billet Circle D 3200 converter really sweetened the combo. Very happy on how this setup came out.

2005 Chevy 2500 with a loss of oil pressure and some serious engine noise. Customer decided to let me do some playing. Found a low mileage LQ4 6.0 and sent in a Gwatney Performance Innovation Truck camshaft with supporting valvetrain. New Oil pump, All new gaskets and a set of longtubes. What a drastic difference over stock. With cam selection and combo this thing makes some awesome torque. Video in comments. 🔥🔥🔥
