I have a decent collection of '60's car magazines, and from the Ford/Shelby ads in all of them, I can tell you that LOTS of engine parts were available over the counter at Ford dealers. Solid lifter cams, tri-y headers, Cobra valve covers, single four barrel, dual four barrel and three-two's manifolds were ALL sold over the counter at pretty much any Ford dealer. The dual-four manifolds shown in the ads were equipped with a pair of Carters (same as edelbrocks) carbs, but my car is equipped with a Shelby two fours intake made for Holleys. I also wanted my engine to look like it could have been done in the late '60's and as such, I had to resist the impusle to buy chrome or billet stuff. My car also has an early, non-vacuum advance dual point distributer that is equipped with Pertronix innards as well as Pertronix's 7mm black plug wires that look factory original. It's important to stick with a theme to get the right "look" and the only place I strayed was with ceramic-coated try-y headers, and a dry-cell battery.
