We used the cheap spray generic  electrical varnish for my neighbor's 8/1 crankcase.  It is still in perfect condition.

Did you bake it after application?

Baking of glyptol is used for motor windings, but I've never heard of baking it as an engine coating. No, we didn't bake, just sprayed and let it dry. 

I'm not sure I buy the baking story.

Be nice to live somewhere a car interior never gets about 130F. Here it can easily get closer to 130C!

Yes, I feel lucky

I ended up getting a spray can of "Glyptal like" insulating paint, Neversieze brand. Much easier than brushing it on.
Set it out in the sun 2 days to dry, it's hardened up nicely and looking good.

I think it was 38AC that suggested the generic spray electrical varnish to me.  A very helpful tip, saved me a bunch of time and money. 

Nice looking crankcase, bet you burned some grinding stones on that!

Yes, you mentioned it Bruce, and I think I read it in 38's build thread. Spraying was much easier and quicker than brushing.
Honestly, I spent about 15 minutes de-flashing the breather opening, and just a bit on the large opening. Most all of what you see in
the pic hasn't been touched with a grinder. And, yes, it did cut like butter with a Carbide burr, which is a little discerning, as it seems like real soft iron. I suppose there's not much nickle in it.

 I brushed one,.. That spray you used looks identical to what I use from W.W. Grainger.
Did you check the rod bearing with the shim stalled or no? The machining in the rod is usually pretty good with errors being with the inserts.  When,the inserts are too thick India adds shims which then yield egg shaped. I.D. when assembled.

There was no shim in the rod. I checked the ID with it torqued up to 55ft lbs, (inserts installed of course). I got variations around the bore but not too bad really.....considering from whence it came. Would I run a Rat motor at 7500 for extended periods under full load with numbers like these? Hell NO. But 500-800RPM and 6-7HP? I think there's some lee-way there for sure.
