Bolt pattern for LS3 to adpter

[pweeks]

Does anyone have a print or the dimensions of the bolt pattern for the LS3 to the adapter plate. Also I need the dims for C/L of the crank to the bolt pattern. I have been searching for these but I have had no luck!
Thanks
Phil

Thanks, but I am looking for dims to build an adapter, not buy one.

Is it like this ...? :drunk:

 

[pweeks]

Yes, just like that!

I "mapped out" the pattern for the engine-side of our bellhousing by using the engine plate holes (after checking the concentricity of the center hole). Lots of triangulation and checking of each hole, but the process was quite straightforward with a 12" caliper.

Thanks Bob!

The bellhousing pattern is the same as the small block chevy except one hole is not used and there are the two additional holes in the bottom that go into the oil pan. PM me for more information.
