Does that sound right to you?
The only possible way then to drive that sprocket would be from within the pan?
That would mean what? a mini-differential gear off of the main
oil pump driveshaft?
Those
oil pump driveshafts are already under a lot of load with just a HV or HP pump, never mind adding on the load of another pump entirely.
Are you sure this is assembled correctly and that the sprocket doesn't belong outside the pan?
Did not know that the Boss 429 used the 'Can Am' system. Does that mean the 385
oil pan rail shares the same dimensions as the FE's? Never really compared the two.
Last minute stupid question. Have you fit the pan you have to an actual FE block? Does the front of the pan extend past the front rail so that the sprocket ends up under the crank snout 'outside' the block (but still in the pan)? Then you would need the special timing cover that covers this extension of the pan and provides the room for the sprocket to mesh with the crank.
