No question for me it was the oldest and still going Speed Shop - Blair's In Pasadena. And still is the #1 speed shop in So Cal. And I still go there. Closely behind that had to be Bell Auto Parts. When I moved to Orange County in 1971, I then frequented Jew & Screw Speed in Westminster (Oops I mean J&S) and Santa Ana Speed (which is also still there) As for Stupid Shops (I mean Super Shops) I never considered them a "Speed Shop", more of a department store of accessories with counter people that didn't know what they were talking about and the main emphasis on selling BF Goodrich Radial T/A's anyway. (They were Michelin/Goodrich's biggest customer and stuck them from Millions when Harry went bankrupt). I only went there when I was in a jam, and always dreaded it. My .02 about the SS's: San Bernardino Racing on Baseline before it became the Super Shops was my choice since was close to home but for the real go fast stuff for my 289 Falcon 2 dr wagon it was J&M in Riverside - no comparison.
