Southern California Mopar Machine Shops

GRC Performance in Lakeside, CA 92040 is where my 318 poly is being built. It is just off I-8, east side of San Diego. Gary Pavlovich is the one who is heading the work and he is THE man when it comes to polys. Give them a call as they do all the machine work and build up including dyno testing if you want it.
