I have noticed that the pricing of cylinder blocks with the correct casting numbers and dates
for first generation z28's sometimes go for very high prices. I understand why this would
be so for restoration purposes. But, on the other hand taking the point of view from a
technical standing, what is wrong with purchasing a brand new small block with 4 bolt mains
from GM. When you buy a brand new block, you get a standard bore, the mains should be
straight and no cracks.
Is this an option if you have a early z and are going to be restoring it?
