And: "C8VE,C9VE and DOVE blocks all have a narrow pan rail."
If there is a CJ/SCJ block from any other year(s) (except D0VE-A that is,) it's unlikely it has 4-bolt main caps.
The CJ for 1968 was an FE. The 385 series CJ appeared in 1970; the 4-bolt main option appeared in 1971. (Unless there are other sites that differ LOL)
The short answer is the 4-bolt main D0VE-A is the CJ/SCJ. All the other blocks are pretty much similar to each other except the truck blocks, labeled D9TE, which have cylinders that are 0.2" deeper toward the crankshaft. The latter are considered by some a little better basis for a stroker engine.
Hope this helps!

All my docs confirm what Tom is saying.
C8VE and C9VE just show up as "429/460-all applications"
D00E-B = "429 CJ AND SCJ Before 8-30-70"
D10E-CA = "429 CJ AND SCJ After 8-30-70"
DOVE = "1971 and Includes 429 CJ, SCJ and Police w/ 2 and 4-bolt mains"
