I left out an important piece of information for calculating horsepower. I have about 7-8 lbs of boost at 4500RPM. More information about the car. I bought it new in Dec. of 1970 so it's one owner. The best addition is front power disc's from a 1978 Concord 4-door sedan. The drums were marginal on high speed stops but the disc's stop like an anchor. I got the whole package, booster, MC, tubing, took the spindles loose at the ball joints. I have front and rear stabilizer bars and gas shocks. Stops and handles great. There's a picture on Frappr!. Original paint was A-1 Snow White but when I had it repainted I went with Candy Apple Red, reminds me of my 1961 Corvette that was Roman Red.
