As soon as I got it home I did a compression and leak down on it. With a Mopar 590 cam in it, I got compression readings from 135 to 150, with most being closer to the 150. The leak down was between 90-92. Both readings were with the engine ice cold sitting on the shop floor. It’s an interesting engine to say the least, it has BME 426 rods, JE pistons(sit about .007 out of the hole), Dyke rings, a Crankshaft Specialist 3.388 crank, crank studs, O-ringed block, Milodon external oiling, it looks to have all the oil mods to the block. The story I got was the guys grandfather had it built by Herb McCandless quite a few years back and wasn’t run until the last couple of years and only for a short time, then they decided to go LS Turbo. When I saw the oil mods and Crankshaft Specialist crank, I thought who knows maybe it is.
At this point my plan is to hone it 180-500. I have a Lisle 1500 rigid hone with 80/180/280/500 stones. The top ring measured .016. I am just trying to decide whether I need to go ahead and order rings and if I do what ring package do I go with.
