Automotive Careers - looking to get my foot in the door near sacramento

ok the background iam 19 (almost 20) i have been working construction for the last year, installing custom home theatre/audio, home automation,camera systems, basically anything low voltage in multi million dollar homes and it's fine for now but cars are my passion. i live in rocklin california and am looking for a performance shop/ engine building shop job. if not a job i would be willing to work for free a couple evenings a week to learn and get to know the shop. just looking to get started with my career.

i have done imports (12 sec honda on nitrous) and iam building a 383 datsun 510 right now (shhh) thats a secret though so i have some fabrication experience and mig welding experience but still much to learn
