Sick Week....

Why is that a bummer? watching guys thrash to get through the week is most of the fun :) Just make a rule that they can't bring any spare blocks/built engines... if they wanna replace their crank on the side of the road let em.
Exactly. The thrash and hunt for spare parts is what makes it cool as hell.

Spare engines and trans and axles etc will now all be available. Kind of takes away from it if you ask me.

I’d be okay with rules against fully built engines and transmissions etc. spare blocks and disassembled engines would be ok . I just think you’re gonna open it up to guys and gals having a purpose built engine for the strip, swapping it out in some hotel lot for a street engine and back and forth.
