NOS Blocks
By Royce Peterson - 01/13/2002 7:41:21 AM; IP 152.163.206.211
These guys still have a few left but none are for sale. Both Greg and Jack have enough money and project cars of their own to justify keeping them indefinitely.

I think they ended up keeping around 25, the rest needed welding, sleeves or were not repairable. That's why NOS blocks should be regarded with caution. If you see blocks with paint marks in the lifter valley such as "006" or "008" etc. these factory marks were referring to the final decimal point in the bore size ie. 4.236" or 4.238" in the example cited. As you can see this is too big for standard bore. Some of the blocks had other types of problems like one or more of the main caps drilled in the wrong location or the water pump holes drilled into the cylinder wall almost all the way through.

Some of these rejected blocks were showing up in Dallas, Texas in the late 1980's and people bought them with no guarantee only to find they owned a NOS block that needed four sleeves and 1/8" decking of the caps to allow a line bore to clean the mismatch. Then a custom timing chain set was necessary to get rid of the slack, etc. Very expensive and time consuming. Buyer Beware of NOS 427 blocks!
