Im thinking about swapping my cams out on my 2004 GT... Im not completely sure whether i have a windsor or romeo engine, and that makes me question the cam gears. i have read that some of the cam gears are pressed on, and some are bolted on. I also read that the swap can be done using AFM's cam chain retention tool, so i wouldnt have to disassemble the front cover. Also, I am curious as to which cam would be best for me. I already have l/t headers on the car with an o/r x-pipe and flowmasters, and a cai. I want a cam that lopes but i would like to keep the rpm's below 6500 since im not sure how much the stock bottom end can take. I already have 4.10's out back so im fairly confident it could handle a decent cam. Also, does any one have any idea how the cams might effect emissions??? Thanks for your input.
