Welcome to M&M LC FoMoCo only made 4 bolt 429 blocks. No 4 bolt 460 blocks were ever produced. All Boss 429 Mustangs and 70-71 429 SJC Torino/Cobras and Cyclones and Mustang/Cougar in 1971 were the only cars that they came in. They really are pretty beefy with just the two bolt mains.

The 4 bolt blocks 429 blocks are few and far between and the 460 stuffs also fits them without any problems.
The two casting numbers that may be 4 bolts are D0VE-A and D1VE-A. The CJ's usually have CJ cast in the lifter valley. The best 2 bolt 429/460 block IMHO is the D0VE-A. It has the thick main webs. The D1VE blcok has the thinner main webs in most cases. But both blocks usually can be bored .110" over, .080" for sure without sonic checking.
If someone knows what they have, be prepared to pay over $500 for one of the above blocks.
