None in the Columbia area that I know of ( I`m in Aiken ) , but two that frequent this site are Brent Lykins and Keith Craft .... also Barry at Survival Motorsports in Detroit ( Wrote a book on how to build max performance FE engines .... literally ) .
Closer to home is Blair Patrick . He`s a little further than the distance to Rock Hill from Columbia ... you should go to the FE Forum and do a search . Site is strictly a dedicated FE site .
