1968 Camaro "Badmotorfinger" v2.2

[fleet]

This issue is probably not due to the name change ...

One more thing while I'm thinking about it. A solid roller requires high spring pressures to operate properly. The cam is dependent on windage slinging oil up on the camshaft lobes for lubrication. Your idle speed should be at 1000 rpm or higher for proper lube. When the car is started cold, I'm sure it doesn't like to idle. You should keep the rpm up to lube the camshaft right away.

Yep idle has always been higher than 1000 -- currently about 1200. And it actually isn't too bad on startup. I hold it in the teens for a bit but it seems to "settle" easier/quicker than I would have thought.

If you decide to stick with bronze, checking timing is important and so is the blocked bypass. One instant indicator of timing loss is a lower idle speed hot.

Yeah a call to Stahl is in order for tmrw for sure. I forgot about the nature of your first engine issue.

I think I (or maybe Rich) will call you about this. Thanks Todd.

Grunge died for a reason perhaps.
