A budget of 35-40 will put Shelby, Kirkham, ERA & Superformance out of reach.

Quality Backdraft cars start in the low 40's used and go up. Shell Valley, Factory Five would be in that range. Quality can vary dramatically between FFR builds from what I have seen.

Also you are most likely looking at a an older 5.0 mustang motor at the price point.

There are always exceptions but this is what I have seen in looking for the past 3-4 months. Look at cobra country website to get a sense for the market and ebay.
