No one believes me but
www.pistonslap.com My Tundra sounds just like my 06 Silverado. Had the high output 5.3. Aluminum block just like my Tundra. Dont tell me its HP and 32 valves ect ect.... My wifes 32valve Northstar dont sound like my Tundra. It's as quiet as a mouse pissing on a cotton ball. My 1970 Olds 442 with 420RWHP dont "tick" like it either. I dont care though I do believe its just the normal sound of these kind of motors and we just have to live with it.
