Could someone please post the specs for a LS5 454 engine. I am really looking for all the specs of the engine, cam, heads, intake, carb, compresion and hp ratings. I currently have a set of 70 ls5 heads, a 72 454 block and a ls5 intake and want to know the hp for this engine and the cam specs so I may build close to factory as possible. thanks for the help.
