Scott McClay is running Rick Liuzzo's old engine and I believe car as well. It was a record setting combination in C/ED in the late 90's
I know Rick went to the Winternationals in 2008 to help Scott with the car and said the engine was five years old at the time.
Long time ago but I think it was originally a 301 and they list 306 now, so at least it has been freshened up if not a new engine. No idea on the chassis.
