Nice car and as much as I appreciate Robert and all he's done for the FE world... That is NOT a Thunderbolt. Clone, tribute or T-Bolt wannabe but it's well known how many were built and this isn't one. Putting a tear drop hood on something doesn't make it a T-Bolt nor does a 351 Cleveland in a 71-73 Mustang make it a Boss 351. I don't own either but this stuff makes me crazy..
Robert describes it as a "clone" in about the second sentence of the interview. As clear and honest a representation as possible.
As far as I know there are only a few of the original cars alive that are still getting used on track. The rest are in air conditioned grades or museums.
I think the Dallas Kelly car might be the only real one running in Super Stock.
Paquet's car has a one off "real car" history without being a real car - built and raced at the original time, by the original folks, in the original place.
Featherstone's car was actively racing not too long ago - don't know now.
