Idea for a virtual and true ENGINEMASTERS CHALLENGE

Opening it up to anything can invite Victor & W9 heads which is not a budget option for most. So it yourself’ers can claim a cheap head, used parts and port .....
I think It would largely depend on the budget cap. Let's say you can spend $5k max including machining costs on the whole engine, no sweetheart "I bought this 426 from my buddy for $2k" bs. It's going to be difficult to build anything exotic with that kind of limit.
