When I was racing the 66 Nova.....I sprayed it a little too much and took out a Piston (Hypereutectic) and it took the rest of the engine with it.......I had a new Engine built with the "Good" stuff in it......after installing eveything.....just like you ..."ALL" I had left to do was put in the Distributor.........I put it in but couldn't get it to seat on the Intake........turns out the Engine builder didn't put in the right Oil Pump to Distributor drive shaft........the Nova set-up had a shorter shaft and the longer one wouldn't let it seat..........I can laugh about it now....LOL........Like you I was 5 minutes from starting it up.........Needless to say, it had to come apart.......The Engine guy said.........Oh Yeah!!.....That's right....I put the wrong one in........Sorry!!.....and walked away.....Lesson Learned......
