Hello. Been awhile since I have been on the board (so long I had to re-register). I am looking to install a 509 cam in my 69 GTX. It has the stock 440 375 hp motor, 4sd, 355 gears. I realize there are better choices now days but I have my heart set on this cam. My questions are, what am I going to need for this swap? Springs? If yes which ones? I am guessing pushrods. Any ideas? Stock rockers ok? Thanks for any help.
P.S. I did look through pages of searched info. Could not find specific info on this.
