"Day Two" modifications are ok...even if you add them 40 years later...

A lot of musclecars had what the buff magazines call "Day Two" modifications-i.e. aftermarket upgrades done immediately after buying the car. Good examples would be 4-speed Chevelle or Camaro owners installing a Hurst Competition Plus shifter in place of the awful Muncie unit. ( They were body mounted and were pratically impossible to shift above about half-throttle. GTO's,Firebirds, and Olds 442s had Hurst Shifters from the factory. Why Chevys didn't, I don't know. ) Another would be Ford guys replacing the awful Autolite 4300 4bbl with a Holley. Others would be Accel or Mallory distributors. GM cars had decent points-they'd go 6,000 rpm or so. Fords and Mopars? Theirs tended to "sign off" about 4,500 rpm and start to bounce. It was rare in the '70's to see a Mustang or Charger at the strip with a stock distributor. If you did, the guy had extra sets of points in his tooldbox! And they were usually aftermarket-like Accel. So be a little flexible when looking at a 40 or 50 year old car. A '69 Camaro with headers and traction bars and a 650 Holley on an Edelbrock Tarantula manifold is just as "right" today as was in 1971. A '60s or '70's 'Vette with headers and chrome sidepipes is just as cool today as it was in the early-'70's. Ditto for a Sun tach on the steering column or a set of Cragar S/S or American Racing Torq-Thrust mags. Much better than an LS motor, and 20 inch Center Lines!!  Just had to vent that. Mastermind
