Ok guys these are the guys that do complete engine blocks right down to Isky cams (before they bought their own oven). they quoted just over $100 per crankshaft for this batch. They told me it would take around 50hrs to treat the cranks. This isnt the first batch we have sent them but I can tell you if makes a huge difference in strength.
Here is their website

We will be sending cranks out to them after nitriding the middle to end of january.
