Default Thrust angle

Have my PV (I)O360 temporarily mounted to start laying out FW stuff. Haven't measured it yet but there's a pretty noticeable right lateral thrust angle. Searching through the plethora of docs, I didn't find anything related. Could someone steer me to the right place or otherwise help me out here?

Much thanks.

IIRC the engine centerline/thrustline is offset from the longitudinal axis by 4

F1 Boss could be a resource here...

Haven't heard anything yet. Did a tight-line measurement and calculated 1.2 deg right. Vertical basically 0 (pre-sag). A quick calc tells me a couple of 1/8 shims at the left isolators will only get me to ~2.4 degrees. Am I overthinking this?

the correct offset is built into the mount. No need to measure, shim or otherwise fuss about. Just put it together.
