5s386-really good info. and certainly not mentioned in the auction listing-which, btw, I thought was poorly prepared. I would have been a bit perturbed learning on day 3, after having bid to 100k, that the engine was from a '74-a '74 what we were never told. But, you could buy a date code correct engine after the auction for another 5k. All in w/o the replacement 351 was close to 120k. Add in the cost of the replacement 351 as well as the other inevitable costs to complete the project (like the missing quarter panel bades!), you'd be at 150k w/o breaking a sweat. Not even close to worth it imo and nowhere near market-again, imo. I'm guessing the buyer doesn't care... or just looks at things a bit differently than I.
