Need help with this vacuum reading

shadango said

I did a couple compression tests.......seems fine there.....pretty consistent across all cylinders...two were a little higher....as I recall I was up around 150-160 warm. As far as leakdown, all I did was let the comoression gauge sit and watch the needle for 30 sec or so...didnt see any drop....not sure if thats the right way though...

150 to 160 warm is just fine, so that's not a problem. That's not the way a leakdown test is performed, but it looks as though you don't have a burnt valve which will cause a vacuum fluctuation.

That cam is too big for your application and is indicative of the driveablity issues we often mention when suggesting the correct cam for the application. If you have power brakes, I imagine they don't work worth a darn either.

It's time for a cam swap.
