Which machine shop? Bostons about 60 miles from me, maybe I know them?
Did they give you a build sheet? Do you have any specs on the internal parts? what pistons, camshaft, springs?

Could be they only built a driver with a "small" cam.. but without any specs, you'll have to do some digging to find out what is there.
