| Thank you for the wonderful post. I think I understand it a little better now. I've heard others say that they recurved their distributors and it really woke up their motor. My car just seems a little lazy in the midrange. When I cruise at 30mph and step on it to 3/4 throttle, it kind of dogs a little. If I mash it to the floor, the tranny shifts down and it goes like crazy. I realize that with 3.25 gears, an auto trans, and a 2 ton car it was never meant to be an all-out performance machine. When I adjusted the initial to find the max before pre-ignition, it didn't really do that much one way or another to performance. At least for a 0-60mph road test. I've heard that fine tuned timing can matter as much as 30HP on a chassis dyno. I figure with a tired 428cj/auto I'd probably only see 200HP rear wheel anyway. I was also wondering about timing chain slack. I moved my crank back and forth to check it, I could get maybe 5 degrees crank rotation before the distributor rotor would move. Not sure if that's within tolerance of not |
