Hello Everyone My name is Travis Blades, I have a 1998 ford explorer 5.0. I just rebuild the Engine, Trans, 4406 T-case Swap, and rebuilt the 8.8 rear end. Ok so on my engine i can hear my valves ticking at any rpm and at any temp. The engine has about 1.5hrs on it now. I was wondering if this is normal and it has to break in more? I let it run for 30mins and kept the rpms between 1k-2k then i changed the oil and drove it around town for an hr. Engine specs are
Comp Cam 266hr Roller cam
Comp cam lifters
Comp cam push rods
Comp Cam Double springs.
Stock 1.6 rocker arms
Stock intake and headers (torque monster headers soon)
Computer is updated to 2001 but otherwise stock (Tuning coming soon)
Compression is about 9.5:1 Running 91 octane atm
3:73 gearing
Also it seems to lack a little bit of power i thought it would be faster, I got 0-60 at 11 secs. I think the ticking would be from the stock rocker arms, they looked ok but they have 290k miles on them. I torqued them down to 20ft lbs when the valve was closed. I Torqued them all about 5 times at different cam spots. Push rods are the same length as stock. And i have no vacuum leaks. Timing Should be prefect, Dots aligned up perfect. What do you guys think would cause the ticking and power loss?
