OK..my turn. Anything over a stock rebuild is where the costs are. For a basic build, I would say prices are 15-20% over a 440. Cast pistons are available. King makes the bearings. New and reground cams are there. Melling recently reintroduced the oil pump. Fel-Pro still manufactures the gaskets, along with BEST Gasket. Getting it into the car is another subject.

There are 12 different early hemi engines sizes, and yes....they have all been 392's at one time or another.
