$50 Craigslist 360 EXTREME budget rebuild??

On a sizeable bet I would want to be able to drive car in the garage at 7am Saturday morning with the 318/904 and able to drive out 7pm Sunday night with the 410/A833.
I would just buy a 727, stall converter and all the makings for the 410. A 318 don't have enough poop for my wife.
but then again, neither would the 410. ha ha
