hahaha I really don’t know what I was thinking with that. Although a an20 would of just about fit the opening in the crankcase. I doubt there would be enough room for the 90 degree fitting to go between the exhaust. I could place the exhaust further away but then it’ll be too close to the rad.
The reason I want to run a large breather is that I’ve opened up the ring gaps and want to run reasonably high boost so I’m expecting more blowby. A buildup of crankcase pressure is never a good thing, it’s easy to prevent now with large fittings and a catch can than have to replace the lot later on down the line if I run into breathing issues.
