Damn, Nemesis . . . I truly feel for their overseas customers
I'm still waiting for my engine, they are having problems keeping up with their custom engine program, and they sent out a mass email. Still, many have received quality production and custom engines from them, and some have had big problems, like you. I hope the dice roll doesn't come up snake eyes for me.
I had expected up to a year wait, and it's getting close. If I have any problems, you guys will be among the first to know, and I expect and will deserve a hearty "I told you so" if I do have problems.
I do feel, overall, that they're a good builder that has made *some* great engines, but they need to be better organized and improve communication and customer service.
But the block issue you're having is a big one. Keep on them, and keep records of all the work you've had to have done. Come to some sort of agreement and get it in writing. Hey, if you want to visit the US, a trip into North Carolina and a rented car might be in your future to give them hell in person . . .
