The first 6.1 failure that I heard of, went while the engine was at idle. This was a fresh build with a factory shortblock. He sleeved the cylinder and rebuilt it to a 414 stroker and is now going with a direct port nitrous setup.

i'm spraying mine. i sprayed my hemi truck with a 100 shot for about 8 months no problems. I know several people with 2 stage systems with 100 shot each stage on stock motors that are fine. when you exceed that is where you're on borrowed time. I'm going to a direct port myself with a 150-200 shot on my 392
