"I don't need some BS numbers...just a fair number that I can figure if my chassis is working right." I agree 100%! I'd much rather have a "stingy" dyno,with a little lower numbers...than a "Happy" one that isn't even close to the TRUE power level! That would only bring on a major disappointment when the car gets to the track! If I get a TRUE 600 horsepower out of my modified 440,I'll be a "Happy Camper"! Anyone know what it takes to hit 10.8-10.9 in a 3730 lb.(race weight)'69' GTX...which was running 1.54-1.56 short times? I will be with Raff tomorrow,and taking pictures....as well as videos! SHOULD BE FUN!..and interesting!
