Not SFV, but relatively close in Simi Valley, check out Addiction Motorsports. Owner Eddie Rios is the man.
Don't let the pics of mostly Fords at the website put you off. Eddie has owned a Hellcat Charger personally and when I was at the shop last year for Power Stop brake pad swaps, his wife drove up in a built late model Jeep with drag radials at all four corners.
That day the shop had everything from some old musclecars getting wrenched, a late-model Caddy getting a pulley and tune, two full-on drag race cars, and a wicked sounding Pro-racing Baja offroad buggy getting dyno tuned.
