It's not original? Say it isn't so!!

Is everyone as sick as I am of so-called "experts" poo-poohing otherwise excellent cars because, even being 40 or 50 years old, they don't have the original engine, transmission, carburator or distributor?  Musclecars led hard lives. People drove them on a daily basis and wrecked and abused them just like you do your 99 Honda Civic or 97 Ford truck. If you find a 67 GTO with a 400 out of a 73 Catalina, don't panic. In high school a friend had a 440/Six-pack 69 Super Bee. He blew the original motor all to hell one night after missing a shift. I mean, rods out the side of the block, grenaded. We went to a junkyard and got a 440 out of a wrecked Chrysler Imperial. The only reason he didn't accept a free 383 from a buddy was that "B" and "RB" engines have a different deck height and the intake manifolds don't interchange, and he wanted to keep the tri-power on it. He drove the car another 3 years with the "unoriginal" engine before he sold it. I had a 68 SS396 El Camino, that blew up. I was short on money and the car was my only transportation. My cousin offered me the 327 out of my aunt's wrecked Impala for $100! The 275hp 327 ran like the proverbial scalded cat, got better gas mileage, spun the wheels less, and the car handled better because of less weight on the front end. I drove it another year before I sold it. Here's another scenario- Grandma buys a 1970 Pontiac Formula 400 Firebird because she wants a "Sports car." She only drives it about 5,000 miles a year. In 1978, even though it only has 45,000 miles on it, it starts running crappy, gets lousy gas mileage and is hard to start. She takes it to her trusted mechanic. He tells her it needs a new carburator. She says fix it. He buys a rebuilt Q-jet from Pep Boys, or Checker, or Napa, or whoever he buys parts from and turns in the numbers-matching carb for a $20 core charge. The car runs good again and granny's happy, not knowing that 30 years hence, when grandma's kids sell the car after she dies, some asshole who wants a concours show car is going to be miffed because not only is the carb wrong, the mechanic 30 years ago used the wrong kind of hose clamps!! Get over yourselves people!! Your Coker tire replacement Firestone Wide Ovals aren't original and neither are your Legendary Interior seat covers or the Autolite battery cover on the Exide or Die Hard battery!. Mastermind
