I have a 455 block with C heads but from what? any help is appreciated.

 

30M622283
3 = Oldsmobile
0 = 1970
M = Lansing assembly
622283 = 22,283rd assigned TORONADO VIN

the "C" heads are from something else 1967-'69

 

 

I sold a 69 block from a delta 88 and looks like I kept the C heads.
had a block done and it must have come out of a Toro.
Now I have a N crank looks like 397363 any Idea what that came out of?
the delta or the Toro? Or could it have come out of either one?

 

 

That casting is very common and came in all but the 1968 forged steel 455 crankshaft engines.

 

Thanks everyone
