Two Guys Garage and ARP are collaborating on a massive 13-episode engine build. Beginning with a bare block from DART, Kevin and Willie are on a quest to harness 700 HP from a naturally aspirated LS Engine.


Willie B introduces the Dart LS NEXT SHP engine block that will be the basis for the 13-episode ARP Engine Build.


The guys mock up the crankshaft installation to keep the project moving forward, including ARP studs, steel crankshaft from Howards, and King Racing Performance bearings.

Rods and Pistons

The high horsepower project moves forward as Willie and Kevin continue mock up with JE Pistons, racing components from Howards and ARP fasteners.

Camshaft and Lifters

Mock up mode is coming along. Willie walks through file fitting rings in a few easy steps. Kevin gets technical about ring gaps and introduces the Crower Roller Camshaft.

Cylinder Heads

The guys outfit the engine with an AFR Mongoose LS3 head and discuss best practices for torquing and checking push rod lengths. 

Piston to Valve Clearance

Willie and Kevin check piston to valve clearance in anticipation of starting the final assembly. 

Valve Train

Willie and Kevin install a Jesel belt drive for on-the-fly cam timing adjustments; insert the correct length push rods; and cap it all off with a shaft rocker arm system.

Intake and Throttle Body

The guys shift their focus to airflow, installing a Top Street Performance High Rise intake and capping it with a 102mm throttle body.

Fuel System

Addressing the fuel system, Willie and Kevin install Top Street Performance fuel rails and a set of injectors from Fuel Injector Connection.

Dry Sump Oiling System

Willie and Kevin install and explain the benefits of an AVIAID dry sump oil system and finish the install with an ATI balancer.

Sensors and Wiring Harness

The guys tend to the electrical systems of the motor by installing SMP sensors and a custom wiring harness, so everything can talk to the computer.

Finishing Touches

It’s finally time for all the hard work to pay off, but first there are some final touches to be made. Once everything’s in place, the guys start the engine for the first time!

On the Dyno

The day everyone’s been waiting for is here, and it’s time to see what kind of power this engine will put out. At the engine dyno, Willie and Kevin make final adjustments and finally get to hear what the engine sounds like at 7000 RPMs.
