Did your machine shop use a torque plate when machining your motor? and if not... how's the motor doing?
There isn't a machine shop within 50 miles of me (or farther... I haven't checked) that's got torque plates for the LS motors. I talked to the guy locally who comes very highly recommended by, well, pretty much everybody, and he said that he's only got them for SBC, BBC and a couple fords. He also said that they're entirely unnecessary, and offered to bolt one to an SBC and show me the measurements with and without it. He reminded me that GM never used them when they did the initial bore & hone.
So, what it boils down to, is that if I want a torque plate bolted to my motor for the re-hone, I'm going to have to bring my motor to somebody way out of town instead of using a local guy who is highly recommended by everybody I know.
It's easy for everybody here to recommend that I find a shop that uses the plate, but what I want to know is who had machine work by a shop who DIDN'T have a torque plate, and how's your motor doing?

If this local guy does this for a living and is good at it why wont you take his word?? I mean an engine is engine is an engine, generally speaking of course.
That's what most of the knowledgeable machine shops around here do.

I just had mine done last week. He used a SBF torque plate. Said the holes lined up almost perfectly.
I would make sure they use the torque plate. The alum. blocks flex more than a steel block. This is why the head bolts go all the way down to the base of the sleeve. Helps spread the pressure evenly across the block.
If he doesn't use the torque plate, you run the risk of having an outta round cylinder and faster wear on the rings and crap.

If it worked then, why would it not work now?

Where are you in Ga? I use a shop local to me that does some work for Vengeance from time to time. You do not want that block final honed without torque plates...find one that has them.
