The kit from Holley is very similar to the kit I put on the ls motor in my 4wd blazer. Looks to me like it uses the same water pump as the ls. The kit for the LT motor uses spacers behind everything to bring the pulleys in line with the crank pulley. The water jackets on the LT are machined different than the LS, therefore spacers have different machining on both sides as well as threaded hole for temp sensor. Holley LT accessory drive part number 20-170. The intake was a new replacement intake for a Camaro/Corvette LT1. The headers are speed engineering shorties. They make a long tube header also.
