why do install instructions say this?

mine is in the garage, patiently waiting to go on. If you got the intake, adapter and gaskets you're set. Some tools are handy, what most don't have is a torque wrench, I'm getting one for this job. Get some RTV, teflon tape, and some hose clamps, these are just foresight. I also got a new T-stat and gasket, cap and rotor, and coolant temp sensor, thses are just cheap maintenace. Did you get that adaptor yet, your t-body will work with it, you'll just need to pull the studs out of the old intake.. The strut tower brace will have to go, hock it to a guy with a six cylinder car, you can replace it witha different style, but you don't need to, some guys around here say they don't feel a differnece anyway. good luck, Hef
