Or find a different machine shop that's not run by crooks.
$300-$400 is way too high for just a line bore, should be able to get the entire block redone for that. I only spent just under $500 to have mine done, that included cleaning the block, head, bellhousing and all the tins, boring the block, checking and installing the pistons to the rods w/new pins, head milled .030", all 12 valves replaced w/new guides, resurfacing the flywheel, posishing the crankshaft, and installing new thrust plate and gear to the new cam.
