That's interesting. My engine was bought as a complete standard bore unit from original bellhousing, pan to flywheel for $11,500 back in 1994 from an old farmer outside of Chicago. Then another 15K has been put into it since. Good items don't come cheap but sometimes there are exceptions - deals however are not always what they appear to be.
BTW, is there any way to actually connect an engine to a car with side-oilers/Shelby's? I don't believe the vin was stamped on the block or were they? If they weren't I guess mine came out of #3001 and just went up another 10K.
