Ferris,
Just a thought, but have you considered/checked the clearance space available if you move the engine and oil pan sump forward that far???
I attached a screenshot of the front frame with suspension taken from the '66 Truck Heritage site documents below. IIRC, that oil pan sump doesn't have a lot of clearance in it's original position with the steering components mounted to the rear of the engine support cross member. Could pose a problem with pan contacting the steering center link as it travels back and forth during turns???
Will also affect your accelerator controls I believe.
Just some food for thought.

Finally time to get to work on my Grandpa's (now mine) truck!
The engine perches align with the rear holes on the upper flange of the frame. The 292 engine has a staggered perch, which is why there is an extra hole on the frame flange. If you move the engine forward, then the cast-iron bell housing will not line up with the crossmember for the bell.
Folks who install an LS engine in a 1963–1966 C10 usually move the engine forward a bit to allow clearance for the rear coil pack on the passenger side at the firewall. The same is true with folks who install a SBC with tall valve covers.
Looks like there is room on steering and crossmember. Front set of holes will work on frame, but there is no flat on the cross member for the mount to sit on.
Do people just drill and bolt to the cross member?
I believe those extra holes are on the passenger's side only, for the offset motor mount used with the 292 inline six. Changing motor mount positions will affect a lot of other things, such as driveshaft geometry, clutch linkage, fen to radiator clearance, etc. Jerry
