I would think anything over $40,000 nowadays should at least be numbers matching!
[/ QUOTE ] I tend to disagree with on you for this particular reason (at least on H/O's). The 455 block was brand new in 1968 and 9/10ths of these blocks were ending up in land barge 98's, front drive Toronado's or hot Delta 88's. The hardest these engines ever got leaned on was when they were taking the boat to the lake. Enter the H/O! Factory rated at 390 hp and 500 ft/lbs of torque! What was the difference between the blocks of the H/O and the 98? Nothing! They reported some core shift on those blocks, but when you do not lean hard on them, this hardly rears its ugly head. If they did get leaned on, the block would often go away quickly and the dealer service replacement block came in. My car has a replacement block in it and I don't think any less of it. The '69 H/O advisor stated that there are a lot more with replacement blocks running around than with the original. Also, with only 515 '68's built, you are talking a very limited number (granted, not as rare as a ZL-1 or a Yenko) to be dolled out nationwide. That car would bring more than $40 K, but it won't. The reason, it does not have the flash and WOW factor that the '69 had.
