this is very true when it comes to clifford, they are nice people and make nice equipment but they make some very, hmmmm how shall I say "flashy and tempting" numbers, when I asked them for some dyno numbers which is what they claim their power percentages to be on, they could not produce it, and did not know the actual HP/torque improvements numbers wise, very nice people, but when they tell me that a 261 with their cam/headders/intake/custom head/and fuel injection will give you over 100 percent hp improvements over stock according to them, and a 261 was like 150 HP, well that would mean 300 wheel HP!!!!!! that would be incredible and wonderfull, but we all know this to be untrue and not attainable for a 261, thoughts anyone?
