hi guys,

i just started up my new 355, it has a gm 847 cam, lloyd elloit heads, 1.5cc rockers, new pushrods, comp r's, stock rods stock crank, speed pro pistons.

i started the car up to break it in and i have some major concerns,

first off : car holds an idel and i only have code 16, my o2 read fine and i have a good tune for the car, i'm getting a very small knocking noise from the engine but i cant tell where, or why its there.when i drained the oil everything looked fine... some metal on the top, but nothing that would pick up with a magnet.


secondly: i dont have any knock retard showing... even at 3k... i havent reved past that yet, but i'm wondering if the knock i'm hearing is the rockers... i havent adjusted them totally... but the noise i herd was different than a tick... wouldnt the KS pick up a knock?

can anyone come out to hear the engine..i'll pay yea for your help

 

How did you adjust these?? Don't adjust them too deep. Just zero lash plus 1/16-1/8 turn.

 

double check your firing order too. one crossed wire and it will still run, but make a nasty knock. It's easy to confuse them when routing from the opti to the plugs
