I don't know much about the 5.0... but my buddy just purchased one and was contemplating going either the H/C/I route or just supercharger. So I thought I would consult you guys for some info. IN GENERAL and on average, how much power does a 93 5.0 put down with say gt40 heads, cobra upper and lower, and an E303 cam???? Just need a ballpark estimate of what kind of power these mods make. Thanks guys. And yes I know, it's not the how much power you make but how low your ET's are!
