Hello all,
My name is Woody and I'm from Colorado Springs. I recently sold my 96 K1500 and purchased a nice 2000 K2500 crew cab short bed with the 7.4l engine. I love the truck but it's going to need some work.
When I purchased the truck, it had a real faint, slow tick sound coming from the engine. Almost sounded like a solenoid clicking under the intake. After driving it around for a while, the sound got much worse. I determined that it's the exhaust lifter on cylinder 2. I have a feeling the guy I bought it from knew this and dumped some sort of miracle in a can product in the oil and got rid of the truck.
I like the truck enough to repair/upgrade it. I'm anticipating a cam replacement but maybe it'll just need lifters. Haven't pulled the intake yet.
There are a couple cams I'm considering.
Mainly, the Lunati Street Master kit:
Duration (Int/Exh): 264/270; Duration @ .050 (Int/Exh): 206/213; Gross Valve Lift (Int/Exh): .468/.485; LSA/ICL: 112/108; Valve Lash (Int/Exh): Hyd/Hyd; RPM Range: 1000-4500
The kit is around $850 give or take. The Lunati phone rep said that I could get by without adjustable rockers because it's such a mild cam.
Has anyone tried this cam? I'm wondering if it's so mild that it's not worth the time and money.
The other cam I'm considering is a Howard 120226-12.
Lift: .510 / .527, Duration @ .050: 209 / 213, Centerline: 108; RPM Range: 1200-4400
This one seems to be a little more aggressive. The cam itself is about the same price as the Lunati but I don't think Howard offers an entire kit, you have to buy everything separately.
Appreciate any advice.
