Finally getting ready to carry my new 302 to a dyno. So far the shop has said they will use their headers, I don need a fuel pump, and I need a pulley setup for crank and water pump. He says he has a bell housing. This is harder than it looks.
Any other advice for a first time on an engine dyno/

I would drive it around for a few hundred miles kinda nicely, swap out the oil/filter and then put it on the dyno.
