Hemi bell bolt pattern question...

Is the bolt pattern on my KB Stage 10 block, which has 9 bolt holes, different from the stock 426 hemi/440/383?

The reason I ask, is I ordered a mid plate/glide adapter from TCI. They first sent me an old 392 pattern. Then they sent me a pattern that only has 6 holes. It is really becoming tedious.

 

i have a cad file,want me to email it?

 

That would be perfect.

It took a couple of days, but I can answer my own question now. I pulled the tranny and mid plate/adapter out of the car tonite, and indexed the old plate over the one that has the stock bell bolt pattern. All the holes that were there lined up perfectly, there were just three missing in the new plate. All I have to do is index and drill three additional holes in the new plate. Soooo, the short answer is yes, the KB block has the same base pattern as the stock block, plus three additional holes.

I would like to have the dimensions for the hemi bellhousing pattern and crank flange if anyone has that please PM me.

I have the BBC if you need it, I'll send it.
