No, you will not need a new hood. Rebuild - no, as long as your engine is in good condition. Forged - no and yes, no if you go with about 8-PSI, yes - if more for engine survival.Freds3.8 said:Thinking about adding S/C. Will I need a new hood? New hood + new paint job= major bucks. Also have about 100k on engine. Will I need a rebuild? Mo Money, Mo Money, Mo Money. BTW Froged internals taste like chicken.
