block no.:12551964
heads no.:12556642c 317

do you know of a way to check and see by the number posted what vehicle it came from?

either way, it came from a truck of some sort. either a 2500-3500 truck or a suburban something like that. if you want to know the exact truck, there should be a laser etched number right above the oil filter somewhere telling the last so many numbers of the VIN.

that page helps, if you want to find a certain vehicle with a certain block or heads.

it should be a 5.3

I think your block casting number should be 12551364.
No, BoostedHulk, its not a 5.3.

What vehicle it came from is almost completely irrelevant.
