Modified Stock and MX

Probably would be legal but kind of a stretch. The block & head have to have an OEM part number and the engine type had to be available in a production automobile but you can cut and hack to your hearts content from there. There have been other instances of parts from outside of North America being used as long as it is OEM. I would sure be checking on this with NHRA before I went too far though.
