I don't think you're crazy at all. It is definitely do-able for that price. Sounds like it will fun to drive as well. If you are buying a crank, you should definitely consider a 3.75" stroke and build a 383. "there's no replacement for displacement"..... Just know that all the little stuff adds up, (oil,plugs,water pump, t-stat, filters, gaskets, sealer, etc..) The list goes on and on. But $5500 should build a helluva motor.
