Steve, you are too kind, sir. I've still got a lot of questions to answer. The latest is investigating the possibility the center main bearing wear is caused by crankshaft harmonics and not oiling problems.

Packard was a leader in engine balancing, but they were still in the beta test phase when production ceased. Maybe they miscalculated somewhere. I'm getting an expert to look at the crankshaft balance weights.

Building a 427" Packard V8 is very possible. All it takes is a $2500 stroker crank and an $800 set of pistons, plus about another $4,000 for the machine work and miscellaneous parts. I've got a $1500 set of Oliver billet rods and a $2,000 roller cam kit if the engine is to be supercharged or use nitrous. Figure at least $10,000 to do it really correctly.

I'll have at least that in my Latham supercharged engine for my Studebaker Hawk. It keeps getting pushed back by the Studebaker pickup/Packard V8 and various Studebaker and Packard V8 builds for others.
