parts is parts.
it doesn't matter because whether its a complete motor or not, one stupid broken part renders both, no workie
both parts failed as a result of bad heat treating then both companies stand behind their product. (as it should be).
actually its worse that it happened in the "high dollar turn key" viper motor. Those are supposed to be "reliable motor alternatives"
You are comparing apples to oranges.....
The vipers are complete motors and sold as such...
Raylar is an aftermarket product you add to an existing engine
