Ed,

Check places that regrind racing and high performance crankshafts on getting
the side housings re-nitrided. The process as I recall involves putting the
part in an oven filled with the appropriate gas (boron nitride or some such)
and heating to get the hardening. Sometimes the cranks would warp from the
high temp. used and would have to be straightened after the process.
Also, from previous discussions on this forum should you not be looking for 4
port side housings if you have to change yours? Does anyone know if all
engines after 1988 are 6 port?
