i'm thinken about buying some nice cams for my car and i was wondering how would i install them.. do i just replace it with the old one.. or do i have to tune and adjust stuff so it runs fine ? .

 

Well, You say cams as in plural? More than one? If so, you need to specify what kind of car you have? But if it is a LT1 then some other options are available for cam swaps. Several companies sell kits and there can be a bolt on type thing. It wouldnt hurt to do headers and exhaust while your doing that but you dont have to. Alot of people recommend getting the computer tuned by a pro but it is not neccesary. But It is mostly a bolt on job that can be tackled by a person who knows a little about cars.
