Hey guys and gals, this isn't quite a mustang question but I thought that some of you might know this. I've got a 1976 F-150 that has a 390, it's completely stock except for an edlebrock rpm intake manifold and an edlebrock 850 CFM carb. Now I know that the carburetor is too big for the engine, but I bought it that way. How much HP and ft/lb's am I pushing stock? I think it's got about 275 hp but I'm not sure. This truck may go up for sale soon also if anyone is interested PM me for info and pictures.

 

DUNNO thats a low compression motor that had 2 barrel carb..and very heavy...
