  1. When it comes to pure balls out fun there is no replacement for displacement. These cars were blissful brutality the likes of which we will never see again

  2. GM, Ford and Chrysler all gave false numbers on HP strictly for insurance purposes. A little tweak here and there, the 500hp threshold was easily attainable.

  3. F.A.S.T cars, Factory Appearing Stock Tire. These are basically NHRA Super Stock cars on doctored bias ply tires. Nothing stock about these cars. If you took both these cars off the showroom floor straight to the strip they MIGHT run 13's on a GOOD day…most likely low 14's. A Stock six speed V6 Honda Accord runs high 13's for reference.

  4. I remember back in the 90's you could still buy brand new L88`s from the Chevrolet parts counter for around 5k. I thought that was a fortune back then but I was a broke teenager. I still have the GM performance parts catalog.

  5. This year Camaro was lame looking 67 and 68 were nicer looking and more aggressive-looking car the Corvette on the other hand this is one of my favorite year for the Corvette when they went to the plastic bumpers they ruin them my thoughts were the Corvette would win Corvette is definitely a lot more aerodynamic than that Camaro

  6. It's funny the ZL-1 was supposed to be for the Corvette only (Only 2 were ordered) but because of the COPO system they mainly ended up in Camaros. Most of them ended up being sold at the parts counter. The aluminum block shaved about a hundred pounds off the front end weight which is a big help with understeer.
