750hp,,,,,,,,I've seen the Arntz. It is a very nice car for the money. The FIA Kirkham is my car. I bought a Sunbeam Tiger from Kassabian and consigned my Kirkham, (my wife said something had to go) but I don't think it will sell.
I was Impressed with the Arntz, except the SBC.
The 2003 date was probably when it was first registered in California. DMV wouldn't be any help because of privacy issues. I will be at Kassabian in 2 weeks, Ill take a closer look........Ron
