Build thread for my Baby Ace engine. It’s heavy so I’m trying to work on how I’m gonna make all this happen but here’s a update to start the thread.

Yesterday my wife and I put 13 hours of drive time round trip to go pick up a Corvair engine in Michigan. Cool guy with a Zenith 601 that switched to a Viking Honda.

Boxed it up and drove it back and now it’s in my shop. I have a 2014 manual and I need to do some reading and research.

1st obstacle. I have a 8409 crank with is the desired crank. It’s magnafluxed unfortunately it was found that the crank was not Nitrited. Somehow this slipped through the factory as a mistake and I’m told it’s rare but it’s a known thing?

So.....either I find another 8409 crank or buy a brand new one billet one from SPA? Don’t know yet.

Only the 140 engines had nitrided cranks (iirc). Just send it off to spa and they will nitride it after grinding .010 and checking radiuses.
