Go with a crate motor and save yourself some big dollars and headaches. Local machine shops have a way of charging you for every little detail and a lot of extra labor costs. Walk to the shelf to get a set of freeze plugs equates to an additional $45 labor charge.
A bore job is $230 bucks in my area. Having a short block put together with my parts would have cost me $1800 or more. I built a stroker for less than that(put it together myself) but still had six or seven hundred in block preparation. That's because I had to take it to two machine shops. The first guy sat on it for three months (was told it would be a week) and I got pissed and took it to another which took two weeks.
This was in the dead of winter, no spring rush with dirt trackers.
Buy a crate and have it in two weeks with a warranty. $1000 to $1500 easy.

Sorry for the rant, but it gets a little aggravating around here. Hope you guys are better.
