Thanks again to all. As for seeing the cars at the races, I think you pay about $40/day for full access to all the race cars. The original MO block for my car went into the '68 Camaro that replaced it on the race track. I have an original MO block from one of the early Yenko Zs (Bud Gates' race car) but installed a dated 657 block that was decked (no numbers) instead.
