miss cookie

She came from the factory 275 hp. But when she was a young girl, things were done to her. One was she had a comp cam installed. So I was told. I know her hood was removed because when they put it back on they didn't line it up right. She also has headers and MSD ing. And all I've done was install a cold air intake. And oh, I removed the flow master muffler and put on a dyna flow muffler so I wouldn't shoot myself the noise the flow master made. Shes still loud under a load but normal driving shes not. So with all these little goodies, what horse power is she now? Best guess.
