Thinking of doing a mild cam swap to a 92' bronco with a 5.0 my first question is can i just by a cam and lifter kit and install it with out having to change anything else such as pushrods springs ect. i will do that but down the road its a slow process. which leads me to my next question i want a cam that i can run in an all otherwise stock motor but will be a good choice later when i do other upgrades. any suggestions on certain ones. i know a little about how a cam works but when i look at a cam and it has durations and lifts listed im lost. i understand if i increase the duration then the valves stay open longer leading to more fuel and air and more time for exhaust to escape but can i go to aggressive? to aggressive and i can actually starve my motor of fuel right? wat about lift i have no input here all questions. i would rather not have to swap to another one later so i need some help to not choose the wrong one. and last one can i swap the cam without pullin the motor is there enough space in front of the motor? ive never done this before so i have no idea wat toi expect. just tryin to do some research before i get over my head.
