If I'm doing it right it seems to break down as a flint built 9/20 1973 4bbl manual trans ls9 350 out of a c/20 or c/30... Close to original but no cigar.... |
I don't know man, that's pretty darn close for coincidence, I wonder if maybe your 72 got a 73 engine?
Keep scratching until you find the VIN, if you find it and it matches the truck then it's the original engine IMO. If no VIN, then the engine was likely replaced under during the first year, possibly under warranty.
