Machine Shops in/near Omaha

[scottofksu]

Finally finished "blueprinting" my engine and am getting ready to send the block (GMC 350 - 4 bolt - 10/20) off to the machine shop for:

Cleaning (oven and shotpeening preferred)
Magnifluxing
Sonic Testing
Decking
Offset Boring (if sonic testing suggests it's ok to do so)

I'll also want them to balance the rotating assemble and maybe even assemble the short block (not certain on the assembly part).

Thanks for any references you can provide!
