I had the LT1 set and they were the cheapest pos's I ever seen, power gains sucked too.......maybe different for LS1...all i know is i will stay away from all pacesetter brands

 

There are quite a few guys on one of those "other LS1 message boards" who have had good results with the Pacesetters. They were getting them off E-bay for $220. After polishing they looked really nice and most dyno a 20+ rwhp gain. Do a search on one of those "other boards."

 

wow, i think i might order them! can you link me to a dyno sheet?
