Standard FE 1.850 pilot.

(on the Scat steel cranks you need to remember to put a plug in the back - they are drilled through and that 1.250 hole will let a fair amount of oil out....)

Barry , did you learn that the hard way ?

Is there another way?

Dyno adapter plate covers the hole up.  Pre-oils OK - no windage (hole opens to crankcase...).  Fire it up and grab a mop....
