#8 - @#$%^ (couldnt get the damn tester in the spark plug hole :nonono:

Thats pretty good for 55k miles on a 347 that had a blower on it and has 8.5:1 compression, right?

I didnt even bother warming the car up, because I knew by the time I got all the plugs loosened it'd be cold again anyways. So if it was at operating temp I'd say it might be closer to like 160psi, right?
