Its plasma moly or just moly rings, not "chrome moly". Chrome moly is a steel alloy that is much stronger than mild steel and used for race car chassis, roll cages and any application where extra strength is needed.

Basically the only difference in moly and plasma moly is the application process of the molybdenum coating, and the cost between the two. According to most manufacturers the plasma moly process produces a stronger surface that won't flake off as easily during extended hard use. For a non-nitroused street motor the moly will work just fine but make sure the block is honed for the moly rings. Any COMPETANT shop will know this.

im building a 406, with vortec heads, 3.75 stroke and a lunati 00016 cam, its going into a 4X4 truck for some street use and off road. In summits catalog they were selling plasma moly rings for a pretty decent price.

I really don't think you need plasma for the street unless you just want to have them, usually you see them for 1/16th ring lands but I guess you can get them for 5/64th. I've always used the standard moly faced w/o problems. Theres a bunch on ebay.
