Hello again, I have some more questions re the 6081 and 6466 engines.
1. Is the bolt up pattern on the back of the 6081 block the same as for the 6466.
2. Is the flywheel and crankshaft protrusion the same.
3. Is the flywheel/crankshaft bolt up pattern the same.
4. Does the 6466 water pump fit the 6081 block.
5. Is the external sump pattern on the 6466 the same as the 6081.
