Does anyone know how much rod to case clearance is considered "safe" for the swing of the rod as it enters the cases? I got one of the +4mm Hotrods stroker cranks that wasn't fully machined around the big end. There is one high spot at the base of the beam that protrudes outwards and makes me a bit nervous. Right now with the rod centered in the bore in the 10 o'clock crank position (from flywheel side), I have around .040", as the rod tips forward 30 degrees, it can touch the cases, only in one area. The last thing I want is the engine to clearance itself while running.
This was before I did my second pass of clearancing - I ground the cases back to beyond where the sharpie marker is.
The rear of the case has plenty of room for some reason.
