Idea for a virtual and true ENGINEMASTERS CHALLENGE

IMO, a short list of basic rules would be done. BUT…. I know some smarty pants will find a loop hole.

What’s your thoughts to keep it cheap and level so that a regular Joe Blow can build himself and not break the bank.
How about ideas/rules on ….

All OEM parts only
Block over bore limitations to???
OEM heads only limited to???
Intake limitations too???
Carb limitations to???
Crank at stock stroke only, no off set grinding allowed?

.030 over or what ever can be obtained
Heads ported, no epoxy, what ever valve size it came with or what ever fits
Ported OEM iron Ok
Mess with the stock Carter anyway you see fit?
If a OWM is a Holley, stock cam size only?

This could get a bit nutty but crazy of “Other items” or extremes are allowed.
I can't find a good link to the 2020 "Masters of Motors" rules which I recall being a little simpler, but I did find the 2019 Rules for Early Iron. I'm thinking rules along these lines but simplified--like no EFI, don't care about over bore size, or offset ground cranks as the cubic inch factor takes care of that. Wanna bore you're 318 .125" ? go ahead. I would emphasize stock iron heads only--NO aftermarket EQ/RHS/W2 ONLY production iron.

As for the approved parts list I was just thinking real simple like a few piston #'s (which would limit rod choices), maybe head gaskets, single 4150 carb, oil pump, SFI balancer etc... J.Robhttps://st.hotrod.com/uploads/sites/21/2016/06/EMC_Early-Iron-Rules_2_5_19.pdf
