Whats better,grinding a crank or line boring?

Yes I know Eagle cranks come from China and they used to have the same problems , journal taper and too big a radius .

needsa , check with Muscle Motors for a kit as well as Hughes , being on the other side of the border you are going to get reemed on shipping no matter what. Do you have a contact on this side of the border you could ship to and go pick it up yourself ?

As far as opening the mains , with what you said about that machine shop I wouldn't let that guy near your block to open the main holes , buy a low deck kit .

There are some fast Mopar guys that run at Mission , you should be able to find a Mopar friendly shop some where up there ?
