Re: [6pack] compression and vacuum readings

[tr6taylor@webtv.net (Sally or Dick Taylor)]

Greg---The numbers change with the cam grind and head thickness. If your
engine is stock and in decent shape, look for the idle vacuum to between
18 and 20 inches at 800 rpm. Iginition timing also affects the vacuum
reading at idle. (Advanced timing raises the vacuum signal)

The cylinder pressure should be close to i40 psi. 1  5%.
