I have a 4575 Dominator also, but I've never used it. There were earlier versions used in NASCAR and Trans-Am, C5HM has posted some good photos on the other forum. The 4575's actually seem relatively common, I've known a few people with one or two. You might want to check on the Bangshift Dragweek forum, there was a thread with tips for running a Dominator on the street there this summer. What intake are you planning on using?
