When was the LS/7 454 available fromGM?

[JoeC]

Dream Car Garage did a series on the restoration of a 1969 Daytona Yellow 454 LS7 Camaro. In an early episode, they interviewed the owner who had a pile of original paperwork on the car. His documentation showed that it was purchased from Motion as a 454 Camaro. They didn't say if it was a LS7 crate motor or something that Joel built up for the original owner. They did say that Joel told them he built two 1969 Camaro's with a 454 engine. I would guess that Motion would build the 69 Camaro until the 70 model became available.
