There are probably a few 'fly by nights' shops around catering to the tuner crowd but the only 'real' shop I know of in the area is Parr Automotive. They've been around for years and I've had good luck doing business with them.
Frank Butlers speed shop in Pensacola Fl. closed maybe 10 or so years ago. They use to print a catalog (about 120 pages),rows of 10' high shelves full of anything you could need. they had a row that stocked maybe 400 or 500 cams. aluminum intakes were hung from the ceiling by chains. they also had a large full service machine shop. back in the 80s they stayed busy. there were always 5 or 10 people in the speed shop.I wish they were still in business. the only 2 speed shops in this area are small and don't carry much you have to order most of the speed parts.
