[BAD68GTO]

Did a compression test with 4-5 spins of the motor. now the heat shields for the plugs were in, so I screwed it in with the hose and anyhow it isn't perfect as it might have been not 100% "tight" per se, but for the interest of cylinder comparison, I think it was good seating. To clarify, it was tight with the gauge hose but not wrenched down so 1 PSI might have gotten through or so. The LOWEST cyl was 140 and the highest was 152 and I rested that cyl and got a 149 and then a 145 so anyhow, all were certainly within 8% with the mean at 147 PSI. Some were 4 spins, but anyhow not a scientific test, but anyhow good. There was a slight noise I heard 3 times while cranking and it sounded like a pop or a click, but it was when I was testing different clyinders on the even bank. I know my GTO motor makes weird noises when just cranking sometimes. Think I should do a leak down? I spin the motor for 12 spins with the plugs pulled and igntion off and didn't see the motor shaking really. I again checked the front and sides of the motor and also the back and I see nothing hitting and the wires on the coil packs seem okay too.

I can also pull the valve covers and install my new T&D's (used ones) while I inspect as right now I have stock MOPAR rockers on there. The good news is I can inspect while I put them on, the bad news is there is another variable in the mix.....
