Quote: Speaking of 413s, anyone want to decode the pad on mine?
J 413 TH
Casting date 5/5/73
There is no casting number on the block.
Look in the back along the bellhousing flange on the top, by the oil pressure sending unit, should have casting number 2658 836.
I'll take all of the industrial 413's you guys don't want. I haven't seen one yet that can't be bored to 4.25 and I have a couple that can be bored to 4.32.
