Yes, those Eagle cast cranks are good for propping the door open. In my case I could prop two different doors open...
For me, any combination that I buy a crankshaft, I'm using forged. If I'm rerunning a stock crank, I'll run whichever. Be it forged or cast. Though I did take two 440's apart so I could have the forged crank out of the one instead of using the cast crank out of the one I was building (plus it was a 4spd, needed the pilot bushing hole)
