A bit of Mopar History here for sale on Ebay THIS IS NOT MINE

It's a bummer there's not more numbers on these parts.

I have dyno and head flow sheets for the 74-75 Shadow Cam Am/F5000 motors. Directly from Bob Tarozzi who ran the motor program.

Bob is who led Paul Rossi to buy this stuff who then sold to current owner. Paul was not part of Can Am program so there really isn't any first hand knowledge there.
