I think she's old and tired...

Did compression test today on my 66 WM300, measures about 95 lbs on all but two cylinders number 2 and 6.

Number 2 reads 75 lbs but when I shoot oil in cylinder she comes back to 95 lbs; seems like rings for sure.

Number 6 reads 55 lbs and only comes back up to 75 lbs after shot of oil; seems like ring and valve problem here.

Got good oil pressure, after warming up there is about 35 to 40 lbs idling.

I think I want to keep the truck original, I like the 251 driving around town with compared to the 230 I had in the 53 PW.

I guess I need to find an engine shop that knows something about the Mopar flat head sixes.
