Re: 383 Cam Selection

[Gary Pavlovich <glpavlovich@xxxxxxx>]

Dennis,

My first thought is that you could use a much larger cam profile than  222 
degree intake duration at .050"
234 degree exhaust duration at .050"; that is the intake duration of my Poly 
318 HP street cam.

The "size" of the cam is a personal preference to be sure but with the four 
speed you have a lot of leeway on longer duration camshafts as you can 
launch in the peak torque zone when you want max power yet still ease off 
the line with no problems.

My first thought is a fast action cam with a 284adv. and 241 @.050" and 
.500" lift.
My ancient grind 284/.484" Mopar Purple Shaft cam is still going strong in 
my 340 Dart and makes power off-idle to where I shift at 6500rpm.

I would suggest (my opinion now) a profile similar to the this 284/.484 
Purple shaft; if you discover a similar/updated cam with more "area under 
the curve" then go for it but you will be hard-pressed to beat the 
performance of the 284.
