Even with shipping I don't think I can get it that cheap locally. Figure the cost of a good block, machining, etc. Impressive. BTW, what's a BHJ fixture? Matthew

It almost doesn't pay to send a used block out to a local machine shop. I wonder what the quality of the block and specifically the bores are? I've read that some of these places just punch these things out, without plates, and that makes for some low quality junk? I don't know anything about the machine work process, but it would be interesting to find out more about this company's reputation. DG

Grand Imperial Pooh-Bah San Pedro, CA 20859 Posts Member since: 2005/9/7 0:00	I have added my thoughts: STEEL FOUR BOLT SPLAYED MAIN CAPS - Sweet ARP MAIN STUDS - Good choice YOUR CHOICE OF BORE SIZE - 4.020 - 4.030 - 4.040 - 4.060 - Nice to have options DECKED 90 DEGREES PARALLEL TO THE CRANKSHAFT CENTERLINE - Makes sense CYLINDERS FINISH HONED FOR MOLY RINGS - Cool, but I didn't realize that Moly rings required a different hone. CLEARANCED FOR UP TO 3.875 STROKE CRANKSHAFTS - Good. SCREW IN OIL GALLEY PLUGS - Nice. ONE PIECE REAR MAIN SEAL - Duh. ACCEPTS FACTORY OR AFTERMARKET ROLLER CAMS - I would hope. BRASS FREEZE PLUGS - Ok. NEW CAM BEARINGS INSTALLED - Nice. ALL MACHINING PERFORMED WITH BHJ FIXTURES - Ok. FINISHED WITH VHT SATIN BLACK ENGINE ENAMEL - Rattle Can? Finally, what about cleaning up the oil journals and cooling ports? Any epoxy on the valley? Otherwise, it looks like a fair deal.
