sbc crank casting numbers
I have been searching the internet for a couple hours and can't seem to find this number anywhere 3832442. I have read that it could be that it should read 3932442 but don't know. Can someone please help me with this one? 08-02-2009 06:15 PM

When it comes to GM castings 3 6 8 9 0 can all look alike

Machine shops and crank grinders use the last three or four numbers. 442 is one of the most common cast cranks for 350 2-pc. seal engines

O ok that makes some sense. So then it could say 3932442 right. I'll go look again but pretty positive that it says 3832442.

That casting was also used in 267s and 305s, though the machining is different.
