Now that I have your attention...At Mustangworld.com there's a twin turbo 95 gt, it's pushing 800 ponies! If you check out the mods to the engine they do not include forged rods or pistons! Many people here are suggesting that even if you add a supercharger to the Bullitt we need to build from the bottom up. I do realize that that is a 5.0 engine but 800 hp? Do we really need to build up our internals if we're shooting for around 500hp? My (local) ford tech guy says no? Who is the definative authority on this subject? Please respond. Thanks.
