I'm gathering all the components I need for the short pump set-up on my 66SS396, it has an LS-6 crate engine in it. Should I really be concerned about the belts flying off? I won't be racing this car, but will probably drive it the way a 500 HP car should be driven (once in a while). The only part I have for the long pump setup, is the pump that came with the crate engine. I would need all the pulleys and brackets. I suppose I could try the short setup first, but I don't want the belts to fly off and dammage anything. What do you think?
