i don't recall the mopar aluminum stuff, but i certainly do remember the ford and chevy stuff. bought a whole boat load of all that.
at the time they *still* didn't have dick for 455 buick save for a few cams, stock rebuild stuff and like two intake manifolds that were precisely one million dollars. i'm kidding, they were probably like $500 but it may well have been a mil on my line cook paycheck.
i bought so, so many cams from there. i was lucky that i could ride my bike (or walk) to the north hollywood store. later when i was working elsewhere i'd swing by the big warehouse in chatsworth all the time. they did pretty good machine work are really reasonable rates too.
all of that is gone now-- where they were is now condos (i think), and a lot of the speed shops and machine shops closed up, or got bulldozed for condos.
