The Factory 5 cars are a lot of fun too!1967 Shelby Cobra 427 S/C. Straight headers to side pipes - no mufflers. No power anything, no A/C, no radio, no nothing. Car body was 100% aluminum; had 500+HP; car weighed 2200 lbs, wet. Brakes were from aircraft. I don't know what was worse: getting slammed back in the seat and not being able to breathe @ WOT; or feeling the lap belt go through your belly and against your spine under full braking. That car was (and still is) an absolute brutal monster.
40 years ago, it's tested 0 - 100mph - 0 time was ~12 seconds; a published record for a street legal car that stood for decades. For $7500, it was available from your local Ford/Shelby dealer, to order. Today, if you can find an unmolested example, it'd be $1mm +. During 3 years of production ('65 - '67), only 327 427 Cobra's were made; and only a handful of those were S/C's. A very rare production car; and the last of it's breed.
