Just looked again, no place to have motor mounts on either side of the block. Heavy metal/rubber mounts on either side of tranny, along with the engine snubber, and a round metal/rubber pad for the back of the tranny/overdrive. Thanks

Just FYI, if the 356 engine is one that has the side stabilizers they look something like this. This one is the Clipper version and there is one positioned on each side and bolted to the front cross member 4 or 5 inches back from where the front motor mount bolts. It would be kind of interesting to know the reason or the issue as to why some models with the 356 had them and others apparently did not need them. I believe the basic single front mount and each side of transmission rear mounts was the same for all engines.

The front outriggers, "stabilizers" in 1941-47 Packard Clipper Master Parts Book parlance, were added to the 356 from 1941-on to prevent the fan blades (same fan 1940-50) from hitting the radiator/cradle, since the engine torques to the left (driver's side).

The two Packard copper washers, #302770, are .390" inner diameter, .625 (5/8ths inch) outer diameter, .046 thick, but am told by lifelong Packard wrench and parts supplier that the ones from NAPA per my picture, first page of this thread, are fine. You just want relatively soft copper in those two recessed areas. With hard cast iron on either side, 25-30 ft. lbs. torque per the brown 1946-50 Packard Shop Manual will have them conforming without any Permatex, etc. unless like me, a trace makes you feel better.
