I had to put over 50% down because it's 'one off' work. I've had 3 cylinder heads done by them and the work was great. They came reccomended to me by a few members on PATuned and one of the shops on there use them.

I guess doing the work on the end of the crank was out of their ability.

As for timeline, I got on them after 5 months and they showed progress. Then it came to filling those 6 holes and drilling/tapping the new ones. It was said AFTER they plugged the holes and welded them, that they didn't have an efficient way to machine the new holes as they would be going through 3 metal hardnesses at once (crank, bolt plug, and weld).

This is when I told them to wait (Early July) and I started lookig into EDM to get the holes made. Not a single shop got back to me out of 8-10 that I emailed and I tried calling a few with no returned calls. August 7th I went to Indiana for a month to help a new warehouse open for the company I work for and I returned Sept 10th. A few days later I finally contacted the machine shop and they already started on the holes.

It took me a month to finally find a shop willing to nitride treat the crank in eastern PA cause it's unheard of according to the businesses to do a car crank and they are used to aviation and high end machines being done.

This whole project has been a huge headache and would have been more cost effective to just get a donor vehicle and swapped a v6 in.
