Is a 1967 Pontiac 400 block the same as 1968 I am looking to see if engine mounts are same?

No, a 1967 Pontiac 400 block is not exactly the same as a 1968 Pontiac 400 block regarding engine mounts. While they share many similarities and parts interchangeability, there were subtle differences introduced in 1968 that *could* affect engine mount placement or the mount's design itself.

To be certain about engine mount compatibility, you need to check the specific casting numbers on the blocks. Even within a given year, different casting numbers may indicate variations in the block's design that could impact the engine mounts. Different applications (e.g., car model, engine options) could also lead to variances.

Your best bet is to:

1. Find the casting numbers: These are usually found on a flat surface of the engine block, often near the bellhousing or cylinder head area.

2. Consult a Pontiac parts catalog or online database: Use the casting numbers to find the specific engine specifications for both the '67 and '68 blocks. Pay close attention to any diagrams or notes regarding engine mounts.

3. Compare the engine mount boss locations: Visually compare the locations of the engine mount bosses (where the mounts bolt to) on the two blocks. Even a slight difference can affect compatibility.

Without the casting numbers, definitively stating if the engine mounts are the same is impossible. It's a small but significant detail that can make a big difference in your project.
