Pulled the plugs 3 and 6 were not even firing.
I see an opportunity to upgrade to msd coil packs if i can find a set.
MSD still lists them on their site.

Re: Rough idle
So on the compression tests numbers were fairly level except for number 5.
About 145-160ish (psi)
Number 5 was 100 psi.
Further testing determined it was a bad ring for sure.
Not a huge issue at this point.
Will run some compression restorer through the oil and retest after 250km
Gonna try and get my hands on a set of MSD coils if not whats the next best alternative?
If i remember correctly not all 3800 coils are the exact same strength.
Whats the strongest stock 3800 coil?

Re: Rough idle
Just the regular AC delco coils are good enough. I remember you can use coils from a Gen2 and they deliver a tiny bit more zap, but you won't notice it.
