I also am new to this site. I have also been looking for a site like this for weeks now. I ride a Harley and they have a site that is just like this one.
Good people with lots of great information to be had.
As far as the Vette I don't think that you will find anything near your price range. I think going with the Camaro is a much better idea. E.Z. to work on with a small block and you can do much to them as build ups go.
