I was just at the historics and the cars are heavily modded as Toby says. I'm in a bad internet spot right now but I'm trying to upload some photos now. The cars were 1600tis, looked like the engines were lowered, not sure about the trannies (I did see the timing hole). Good bunch of guys but there were less this year. Probably due to the economy. Special oiling capabilities, some kind of pressurized unit from the trunk. And they weren't even competitive like I've seen in the past. I think an Alfa won the group. Ha Ha smoked even the porches.
