Technical dimensions of a 427 Chevdamper

Hi, Does anyone have a big block chev damper they could measure for me? I need the length of the bore, and the width of the seal surface.
Thanks, Joel

 

i can get you specs off mine. i have a 427 eight inch. its snout is covered in tape at the moment. im painting it in the next few days if you can wait.

 

I have one out and available

2-3/16 bore

1-1/16 seal area width

 

awesome, thanks! How we can finish designing the snout of our crankshaft.
