I am confident that the Holley accessory bracket will fit with a standard hood because it is a knock-off of the Vette accessory bracket which keeps everything very low. The big advantage the Holley bracket has over the GM Vette bracket is that the Holley bracket is available with optional ($60?) spacers to space the accessories to the F-Body or Truck position. The Holley bracket by itself gives you Vette spacing. You need to decide on your spacing - Vette, F-Body or Truck as this will determine which balancer, water pump and tensioner you need. I don't think the Truck water pump will clear a stock hood. (Correct?) My LS2 included the truck accessories even though the seller had run F-body accessories in his street/strip car. I had no trouble selling the truck accessories at a good price and buying F-body accessories. If you need to buy a new water pump you might consider the new Edelbrock one, partly because the heater hoses are threaded and not pressed-in barbs which get very close to the Gen-2 control arms.
