My truck started developing a lifter tick while towing last week (confirmed by my mechanic/next door neighbor). Thinking about doing the comp cams stage 1 kit. Specs are as follows:
Advertised Intake Duration: 269
Advertised Exhaust Duration: 271
Intake Duration at .050 Inch Lift: 216
Exhaust Duration at .050 Inch Lift: 222
Intake Valve Lift: 0.52
Exhaust Valve Lift: 0.515
Lobe Separation: 114
Comp cams says I don't need new springs, but the kit comes with new ones. Dumb question, but do I need to put them in?
I have the tools to do it and will be doing the work in my driveway with my mechanic.
Has anyone else done this cam? If you have, how much did it change driving characteristics? Or a different recommended cam/kit?
I do a pretty fair amount of towing (7000 lb travel trailer and a 4000 lb boat) and live in a fairly hilly area.
I'll also be doing JBA short headers, a larger throttle body, a new water pump and the melling high volume oil pump within the next 2 months.
Truck is an 09 1500 and already has a mildly built transmission (roughly equivalent to a stage 4 ATS), S&B Intake, magnaflow Exhaust and a hemifever tune.
My only downside is that I live in CA and need to keep this thing passing smog, so any advice on that would be helpful too.
Thanks in advance and sorry if this has been covered before.
