Howdy. I aquired a 71 duster that has a stuck 340. I pulled the plugs out and was going to squirt something in the spark plug holes and let it sit over the winter. What is the best stuff to use? Thanks

Sorry for quotes but I'm too lazy to retype it all...If it's locked, you're probably not going to have much luck on the same day. You may need to soak it and come back in a few days after it's had time to soak in... or even repeated applications over the course of a couple weeks depending how bad it is.
There's lots of "favorite" brews for soaking the cylinders- Kroil/PB Blaster, Marvel Mystery oil, kerosene/ATF mix, etc. The common denominator is that they need time. And when you try, work it back and forth with a breaker bar, gradually increasing the distance you wiggle it. And don't force it too hard CCW, you'll just loosen the crank bolt.
