Im just trying to figure out who has actually thrown a rod(s) and who has had pistons fail on them while spraying. What kit did you have? What size shot and were you able to pull the engine apart and fix it? Thanks

I threw a hundred shot on my eco before she popped.

Upon disassembling, a valve was bent, the back half of the tops on piston 2 and 3 flew apart.

According to my local hotrod/dragster/engine builder the top ring got hammered and caused the piston to break apart.

He advised staying with a 50 or 60 shot, cuz the stock cast pistons are basically INADEQUATE.

On the way are forged rods and pistons and a ported/polished 3 angle head with stainless valves, dual springs and ti retainers.

There seems to be no damage to the cylinder walls, it looks like all of the piston material either blew into the intake manifold, or out into the exhaust manifold. I'll let you know how "fixing" it goes.
