Performance distributor gear installation

I have given away all the parts I purchased to make the measurements to slant six owners. I did not want them to go to waste sitting on my shelf.

In the meantime, Charlie has lent me two 225 blocks and I have made some additional measurements. The blueprint view of a 1963 170 that was presented to Allpar.com by Willem Weertman and the 1960 cross sectional pictures were not 100% useful until error correction factors for the vertical and horizontal aspects could be determined (this is a problem even when scanning items).

With the blocks at hand, it can be seen that the outer limit of the bore hole diameter for the oil pump drive tangentially intersects the base circle for the camshaft, which makes sense (the teeth for the cam gear comprising most of the difference between the base circle and the cam journal OD). The oil pump drive shaft enters the block parallel to the plane defined by the oil pan rail.

The distributor shaft and gear assembly enters the block at approximately a 15.5 degree angle from the vertical. When the assembly is superimposed onto the blueprint using the cam major axis as its reference point and axis of rotation, the plane bisecting the oil galley and parallel to the oil pan rail meets the midpoint of the distributor gear OD cylinder surface as determined in previous measurements in this thread. This appears to be a confirmation of the proper distance to set the depth of the drive gear.

I hope this information proves useful to someone. I will put up a link of the drawing. I would upload it here but the size limitation on pictures is too small to make the file useful.
