The 484 cam (if it's the old style) can be a dog in the wrong combo. I had a similar set-up in a 440 coronet w/ 3.55's. The car sounded great and ran like heck after 3500rpm. It had no low end. I was running a 175 convert and yanked the cam and went w/ the summit 488, it ran much much better.



What did you have it dialed in at?

no idea motor came in the car. 484 and 509 are good cams, but they like compression, head flow, gear and converter. I wouldn't use either in anything less than 10:1, 3000 stall and 3.91's.




I would be willing to bet the guy that installed it just did a "dot to dot" on it and it wasn't even close. Too bad you didn't check the dial on it before you changed it. You might have been impressed.


Kind of an apples to rutabagas comparison but I run the .509 in my 8.97:1 493 in a 4800 lb. 66 New Yorker. It's the 108 LSA installed straight up. It made over 500 ft/lb from 2000 to 5500 and peaked 600 ft/lb @ 4000. Idling at 1100 was a pain with the stock converter but I had no problem breaking a motor mount in the driveway seeing how much all that torque would increase stock stall speed by. I ran a 2800 Turbo Action converter after that and it drives around town just fine. The only time I took it to the track, it went a no traction 13.92 at 101 thru full exhaust with a 2.76 SG on regular gas. Considering the difference in cubes I would say the 484 would have the same street manners in a basic 440.
