Scoggin-Dickey is assisting me in making this monster GMPP engine work with my fourth-gen Camaro. Here are the parts for this installment: as the crate's electronic throttle will be coming off, SD's cable 90mm throttle body (PN SD90MM, $359) and cable throttle bracket (PN SD90BRKT, $29) will replace it. A new crank balancer bolt (PN SD6621, $10) will enable the balancer swap, two new water pump gaskets (PN 12588372, $8) will do the same for the LS1's water pump, and a new oil pan gasket (PN 12558760, $34) and pickup tube O-ring (PN 12557752, $4) will facilitate the swap of the LS1's oil pan and its accoutrements. Finally, two new motor mounts (PN 22179268, $146) will provide the strength to hold the torquey LS376/480 in place.

The LS1's coils are removed, which makes for one less thing to get hung up on the way down when removing the motor. |  The throttle cable is removed,...

Working in the engine bay's upper passenger-side corner, a 7mm socket is needed to unplug the harness from the PCM. Check out Rob's GM tat-think the TTP crew is hardcore General Motors? |

Three bolts on each side connect the subframe to the body-in front and behind the front struts, and by the back of the lower A-arm. |

Once the motor is halfway out of the car, the cam sensor needs to be unplugged (it's tough to reach, since it's located at back of the valley cover). | |
