Vintage - How quick?

[loose]

Quick Q re the vintage cars that ran at York on Saturday - What do you run in them motor wise etc cos they were fast! Do you just have mid turn modified or are the old cars able to handle serious motors and even brushless? Dont tell me it was all stock motors or I'll be gutted, I was in the stock class and nowhere near your times.

I know a few of you can drive which helps (though watching a couple of you run round the track I'd guess you'd had a few sherbets in the afternoon - lol).

Also, quick thanks to a couple of you for your help re setting up speedos and gear advice to stop us overheating. Its appreciated.
