A word about Ilmor (non-marine)
You get the true measure of a company when the $hit hits the fan. I run a race car rides program, and have recently begun using Ilmor as our engine rebuilding service.
After losing five engines (from a previous builder) in two months, we sent them all to Ilmor for a fresh look. They (and we) discovered that our previous supplier was pretty much grabbing random parts, and there was little consistency or record-keeping. As such, it was very tricky for Ilmor to take what we sent them and turn them into five consistent engines. They did their best, ordered up the custom parts needed (these are old Dodge engines), built up two blocks, and grabbed two sets of "ready-to-go" spare heads that our previous supplier had prepped for us. Long story short: both sets of heads had problems and had to be removed, dismantled, and sent back to Brodix for repair/refurbishment.
We headed off to our next event with <zero> spare engines and promptly experienced more problems, threatening to cripple our capacity to provide rides for our client's guests. I called Paul Ray on Saturday afternoon (in Edmonton for the Indy race) and explained the situation. He in turn called Dave Dixon and got a plan going. We had one set of brand-new, built-up heads in our truck, so we got two of our guys to drive them from Delaware to Michigan on Sunday afternoon. At 6:30 AM on Monday morning, they met the guys at Ilmor, who dismantled and totally inspected the heads to make sure there were no problems, installed them on one of the previously-dynoed blocks, machined the intake manifold for a proper fit, assembled the engine, re-dynoed it, and got our guys back on the road by 8:15 PM that night. They also committed to having another three of our other engines ready to ship by the time we leave for our next event in two weeks.
That, my friends, is S-E-R-V-I-C-E. Above and beyond.
If anyone has any doubts about Ilmor's commitment, let me know.
