I agree with dadodgekid wholeheartedly. When I first started racing my Coronet way back when, it had a 448" in it that was a stroked 383" with the offset ground 440" crank @3.90 stroke. It weighed in at a whopping 4500 lbs. race weight and was running 14.0's. With just a set of slicks and lots of tuning and testing I got the car down to 12.0's (114mph) at that same porky weight. The cam was small a .480 hydraulic ([email protected]) and just some pocket ported 906's so it definitely performed better than it should have. Put that motor in an A-body and I am sure you could get down to low 11's and drive it drive as a Friday driver. I hammered on that car for 2 years that way driving it 45 miles to the strip and back twice a week. I also drove it daily for the most part and is was very docile. The craziest piece was the 4.30 gears, but I also had 28" tall tires so it wasn't too out of hand. Once you are sure you hit your maximum time/speed with your combo, decide what the next speed is you want to go and build a new combo to get there. Throwing parts at an old combo usually is more expensive in the long run when trying to make a big jump.
