You have to remember Chevy, because of the spoiled child attitude would throw tantrums if any other division got the edge in performance cars. The Rocket 88, Olds version of the Corvette, was a much better handling car and way more power. It was way better than the Corvette or Thunderbird. Harley Earl made multiple designs, some were his known personal cars. He was baffled by GM's decision not to make it a production car. Same goes for the Olds 455 Hemi, Chevy cried when they saw it made 650 HP. Never saw production. The flat cams did happen, some occasionally even broke in half. We had a couple of OK Chevy trucks. Dad's 78 1/2 tononly went 280,000 km on it's original motor till the bottom end went, so so in my books, very well taken care of. Our 75 Cutlass went over 300,000 miles under a lot of abuse under my ex brother in law. We sold it for scrap with a seized on brake caliper and a knock. Wrecker sold it, stayed on the road another 5 years. He blew up his Chevelle's high performance 327, couldn't blow up the Olds 350 despite ditch jumping. The TH350 was no prize either dying behind low power cars, saw a few, could have been the change in ATF, some claim whale oil was removed or GM was just slipping in quality. Either way the LS is king, Anubis on here is a good example, the sbc is finally not the engine of choice for the masses.
