Ok so here is a rough turning of a 4" stroke on a AMC 401 crank. Oil hole hardly moved at all.

Here is the backside of the journal

One of the cranks needed the thrust area welded up so they did that as well.

Here is a roughed stroker crank next to a finished nitrided stock stroke

Crankshaft supply co. fixes and grinds alot of crank shafts..

:shock:

They also fix huge diesel block..these blocks get around $25,000.00 worth of repairs.


And they have plenty of spare main caps as well :idea: :shock:
