I like your approach to the whole thing. And if I were building an engine for myself currently that fit the bill of the challenge I would absofreqkinlutely enter. If for no other reason then the camaraderie and maybe, even if ever so slightly help someone else learn. My biggest hurdle is not having parts that fit the rules and not currently needing an engine built for myself that would follow the rules. I can’t feasibly throw 2-4K at an engine just to enter. Even though I’d like to. I have a completely machined 72 360 and complete bottom end I could put together but I’d have to source a set of heads that would serve me no other purpose than this challenge.
