Some measurements to help folks out...

"Can you provide the distance from the crankshaft centerline to the bottom of your cast pan?"

Roughly 2 13/16" from centerline to the pan rail

Then add

Sump is 6.8” deep from the pan rail to the bottom of
sump

The front section of the pan is 2 5/8" deep from the flange to the bottom
outside of the pan.

Front of the sump is 11.3" from the transmission flange

Allow -0/+1/8" tolerance.

4200 oil pan raw casting before any machining is done. This is pan #2.

The patterns are ready to do the next production run now, if your interested, now would be a good time to let me know so I can get the right number cast/machined.
