2014 Chevy SS LS3 A6 sleeper cam dyno.
A lot of companies claim stock converter friendly but this one truly is! This car drives like stock!
Only mods are headers, exhaust, cold air intake and our custom grind Cam Motion sleeper cam.

Before and after dyno results on a 2016 C7 A8 Z06 we did a few months ago.
546 to 806RWHP
Before is completely stock.
We installed a NK Performance Drift Stick camshaft, Johnson lifters, 2” primary Kooks long tubes, Rotofab Big Gulp intake, DSX aux fuel pump and DSX flex fuel sensor, DSX lid, sent the blower to Kong for porting, pulley and a Nick Williams 103mm throttle body.

In car dyno video of a bone stock C7 A8 before cam, headers and intake install.
We always like to do this to get a real comparison on the same dyno. These automatic cars usually make 20-30 rwhp less due 5th gear (1.27:1)dyno pulls and extra rotating weight. Most of the autos have a 2.42 rear gear vs the manual cars have 3.42. This one made right at 400rwhp stock but it was 104* in the dyno bay. Probably would have been 410-420 on a cooler day. Manual cars we see 430-440 stock.

“Shelbey” likes to call businesses and ask how to do their job and gets pissy when told we aren’t here for tech support on DIY builds.
Imagine calling a restaurant and asking how to cook something or calling a plumbing company to ask how to repipe your house? Pretty stupid huh or is this the norm we live in?

Another DOD delete that were able to save the customer 12k on after the dealer misdiagnosed it for a failed injector then said it needed an engine because of a scored cylinder with 75% leak down.
The problem was a lifter and cam eating each other and causing lifter preload to change as it rolled. This caused an intermittent loss of compression.
When shopping around for a DOD delete after a failure make sure whoever is doing the job is pulling the engine and stripping it down to the short block vs repairing it in the bay. If they are not then they are not doing you any justice!
The oil pan should be pulled to checked and cleaned of debris.
The plastic timing chain damper is brittle and should be changed. This can not be done with the oil pump or oil pan on it.
To get the VVT cam sprocket back on with the oil pump in the way you have to play a game with a pick and screwdriver to walk the chain back on and hope you get it lined up because you can’t see the bottom mark.
Most of these are 5+ years old with over 100k and should be completely resealed.
9 times out of 10 the motor mounts are already broke and there is no extra labor to put them in while removing and installing the engine.

Pay once and do it right!!!
Last thing you want to do is find out you need motor mounts and a rear seal just after you paid someone else to do a half ass dod delete.

C7 Grandsport Corvette A8 we just finished up installing Kooks long tube headers, DSX aux pump, Flex fuel sensor, LT4 injectors, LT4 pump and most importantly a Magnuson 2650 Supercharger.
It’s only on 7lb with the 110mm upper pulley supplied in the kit. We had an 80mm pulley as well but the stock LT1pistons probably won’t like that lol. A 100mm pulley would probably be just right.
Intake temps drop on a pull though and coolant temps stay nice and cool in traffic.
Stock vs modified pulls were both on 100 degree days.
Ajay with Anonymous Calibrations on the keyboard and also had us install a map sensor on the blower inlet so a LT4 OS would work.
It drives so much better like this!

Mild little 6.0 iron block rebuild for a customers rock crawler jeep.
Block sent in for clean, bore, torque plate hone, resurfaced cylinder decks, resurfaced front due to major pitting at water pump seals, crank polishing and balanced to new bob weight.
Upgraded to gen 4 rods, flat top pistons, 243 heads and a low lift truck cam.
This should be a nice smooth idling engine with lots of low end grunt.

Clean ’69 Camaro with a mystery big block Chevrolet came in for poor running and some oil leaks. This one was running pig rich, so we rebuilt the Holley 750HP carburetor and changed the power valve with a 4.5” to ensure proper fuel delivery. Also replaced the plugs, new valve cover gaskets and an oil change. From there, we dialed in the jetting and timing on our Dynojet 224XLC. Throttle response, power and fuel economy so much better now!!
