I'm in need of the crankshaft centerline to "China Wall" measurement.
Specifically, I have a 67 400. But obviously the 425 and 455 should be the same.
I've looked all over and can't find it online for the Big Block Olds. My car is still together/running, and with everything being so tight, I can't take a measurement that I would actually trust. Hopefully someone has a short block or even a spare block just sitting around and can get me that measurement.

Thanks in advance

 

I have a 455 block up on my milling machine and I am getting right around 10.285 That should be within .005 or so. I can measure it a lot closer once I finish decking it and getting it off the machine.

 

Bill, if that is from crankshaft centerline to the top of the China Wall, you have no idea how grateful I am. I've been searching everywhere for the actual dimension. I can find CAD files for any flavor of LS, SBC, BBC, and even Pontiac engines for god sakes. But this is the first time anyone has responded with the actual measurement for a BBO.
Thank you,

 

That is exactly what it is. I will get a better measurement after I get it off the milling machine but that should be within a few thousandths
