I assume your Blazer is a '72? Can you show them the specs for a '71 or earlier model?
The power rating for a '71 350 is 255 h.p. And the '72 is 175 h.p. But they are the same engine.
1972 and newer vehicles are rated using SAE NET. While the 1971 and older were rated at sae GROSS.
Probably a long shot but maybe get be worth a try...
