Default compression

so i finally got around to picking up a compression gauge and this is what i came up with

cyl 1 - 185psi
cyl 2 - 185psi
cyl 3 - 185psi
cyl 4 - 165psi
cyl 5 - 175psi
cyl 6 - 165psi

sounds good???

The Haynes manual says that the minimum compression pressure is 100 psi and the max variation between cylinders (highest to lowest) is 30%.
Based on that I'd say your 3.4 is in very good condition.

I had a guy complain to me one time about how hard the plugs where to get to in his 67 impala with a 327 cause it had headers on it. It is all relative. It is a pain if you do not own a swivel. LOL

Ive had an RS and own a Z28 now. The plugs on the v6 are just ridiculous, the z doesn't get me throwing tools after you've been working on that ONE plug for 15 mins.
