Tom, BFBurk is correct. You can get an Emission exemption letter from the EPA if the block is older than 25 years. If it is a current block, it will be inspected as such. The Capital Area Cobra Club (
www.capitalareacobraclub.com) and SEMA are creating new legislation for this particular reason. I have been the one involved from the beginning so I do know all the in's & out's. It would be better in the long haul to find a car titled as a '65. After we get this legislation passed, it won't make a difference.
You should register on the CACC site or meet up with many members on Saturday mornings at the Vienna Inn.
Good luck
Ed
