    As usual the cam showed up and looks great! Broke in fine. Sounds and runs amazing in my tbi, peanut port 454. Nic has helped me so many times with my decisions, taking plenty of time to discuss things on the phone.... Couldn't ask for a better, more personable cam company to work with! Thanks!
