I'm going to build a low compression 331 somewhere around 7.5 to 1 with a built proof bottom end and run about 20-30 pounds of boost on it. I'm going to use everything off the old doo doo motor exept the 24# injectors but i have to wait till sept before I get back from iraq I'm just over here pilling up my wish list. But first thing is to do a cam swap and about 6-9 pounds of boost on the mach. I knew why the old tired 5.0 was slowing down and i told him he is going to need a bottom end because it wouldn't last but you know how teens can be. Besides that was a little to much for him to start out on anyway he is better off in his 98 gt its weak but its just right for him to get used to.
