the noise is there no matter if it is hot or cold. I tore the supercharger apart and I think I have a bearing going bad. The snout bearings are good. The housing of the blower has some wear in it where it looks like the screws of the blower were rubbing it. I am going with new lifters and push rods and a supercharger rebuild. Does anybody have pictures of stock Rocker arms? I think whoever owned this car put aftermarket ones on. I am not really sure.
