ENGINE

The prevailing question everyone wants answered is:

What does the "-3" stand for at the end of 440 engines?

This is part of the block casting # 440-3 (the full # being 3698830-440-3) which is cast on the side of the block. This number is for 73-78 440's. As far as the -1 or -3 designation, the-3 would mean heavy-duty applications (such as an RV)  and the -1 meaning light duty.  Distinguishable differences include the -3 has a heavy-duty forged crankshaft that is slightly longer than in other 440s, the coolant passages in the block are larger, the block is taller, and the heads are slightly further apart. It seems that although many  parts do interchange, as many or more do not. The distributor may be longer on the -3. Exhaust manifolds and headers may require some clearance room to interchange, and intake manifolds from the -1s can supposedly work on a -3 with a spacer.

TRANSMISSION

	This transmission is a Mopar 727 attached to a 440-3.  The transmission is leaking.  A pressure washer was used to clean off all the spill and spray.  Now, we wait to see where the real leak is.  The culprit appears to be around the linkage.
