Noise!!!!
Been about six days since I woke the ole girl up..Drove it about six or seven miles,got back to the ranch........Heard what sounds like a tapping noise coming from under the hood...This may sound dumb,but I don't remember if I ever heard this sound before..Could it be because the car was not warmed up all the way, or because it is a little chilly outside...Before you all answer,,,,,,,,,, please go out and start those engines and listen,listen ,listen to those perfect engines and let me know something...

A loose rocker arm could make a "tack" sound, Injectors make quite a bit of ticking noise-means their workin'. Get it good and warm, drive it for a while, then see. A "mechanic's stethescope"(long screwdriver) might help pinpoint the location. Watch those plug wires!

Loud lifters? Marvel Mistery Oil. When a quart low add a quart of Marvel then drive the car for 10 miles.
Noisy lifters is unusual in a LT-1. Are you using Mobil 1 10-30?
If your using 5-30 move up to 10-30.

I havn't had it long enough for my first oil change but the guy said he used Mobile 1 but I don't know the viscosity... so I will use 10/30 Mobile 1
