Re: 67 Possible LS1 Swap
This should be more than possible. If the ls1 is stock, those cars made around 315 hp advertised. The transmission is an overdrive with a .69 final gear if i remember correctly, and with those gears and a 27" tall tire, you will be turning around 2000 rpm at 75 mph + or - a 100-200 rpm. So realistically, being that 67's are a few hundred pounds lighter (v8 curb weight was lowest than any other year at around 3000lbs) than an 2002, and they rated the gas mileage of the ss cars at up to 19/31 city/highway respectively. So yes you should be able to expect to get better than 20 with ease, as long as you can keep your foot out of it. Which we are all mature adults here and never press the pedal down too far. I try to tell people all the time that HP is not the enemy in gas mileage. Power to weight ratio is not just for how fast a car can go, but rather how hard the engine has to work, how much fuel it has to consume to deliver the same results. I bet you will get 24-26 all day long. If not better.
