6 bolt valve covers is a 350.
the 350 is a very wide engine with a stroke only ~.050" shorter than a Buick 455 so people often mistake it for a big block.

Other than telling you what the factory HP rating was when it was new, there is absolutely no way to tell you what kind if power an old well used possibly completely worn out engine will put out for horsepower.
