Chevrolet LS3 & 4L65E ’68 Impala SS Install Part – Put the Super in Super Sport

Chevrolet Performance Connect & Cruise LS3 Transplant

In this segment of Lowrider Garage we bring out the hammer, crowbar, and engine hoist as we dive headfirst into transplanting the heart of the beast in a 1968 Impala Super Sport. Now for many, installing a modern LS powerplant and electronic overdrive transmission into an older vehicle might seem like an extremely daunting task, especially once you see the accompanying wiring harness and computer all laid out.

With Chevrolet Performance’s Connect & Cruise LS3 crate engine and 4L65E overdrive transmission, it couldn’t possibly get any simpler. This package gives you 430 hp and all this turnkey dependability and economy comes with the new Corvettes and Camaros. Now all Impalas can be real Super Sports when it comes to performance.

Big things come in big packages as seen here. Introducing the Chevrolet Performance LS3 Connect & Cruise crate engine.

The CPP headers were installed for their designed route that goes perfectly around the stock steering box, framerails, and floorboards.

While on the engine stand, the Holley Performance oil pan replaced the original oil pan and is cast aluminum just like the stock one, but allows more ground clearance, crossmember clearance, and leaves room for the center link for vehicles that have their steering linkage behind the crossmember.

The included torque converter was installed into the front of the Chevrolet Performance overdrive transmission.

Jason mates the 4L65E transmission to the Chevrolet Performance LS3 powerplant after uncrating it.

The special manufactured CPP pedestals mount to the frame with the included grade #8 hardware that utilize the factory holes in the frame, so drilling is unnecessary.

By using this retrofit transmission crossmember kit from CPP, we were able to place the 4L65E trans perfectly and it bolted right into the stock mounting holes on the Impala’s frame.

David from Engle Bros. Fabrication masterfully guides the LS3 into the ’68 Impala’s engine compartment.

The new heart is in place and ready to be all hooked up.

Stay tuned as we “connect” so we can “cruise” this special LS transplant install in our upcoming and next LOWRIDER Magazine issue.
