BBC Clam Shells

[Mr Clean]

I'm looking for a set of BBC clam shells. I put my BB in my Blazer today, got one motor mount bolt in, and the other one does not line up. I used SB clam shells and I'm pretty sure that's my problem. I looked at the Extracab that has a BB in it, and the clam shells look shorter. Let me know if you have a set.

If you are using small block rubber/urethane mounts, then the smalblock clamshells are correct. Depending on the brand and or condition of the mounts, it can take some finesse to get both bolted up. Even if you were installing a small block too.
