| RE: I called Comp Cams about the original 428 cam |

I would agree , I have a couple of files set up in Dyno2000 for 428s , one for the motor in my 68 and another for a motor I am building now . Since your motor is similar I ran a simulation using it and the two cams you describe. The 33-208-3 is about 5 hp better at the peak of 5500 RPM than the "old cam".
I run a solid cam with 227/227 and 505 net lift and the simulation says I make 410 HP at 5000RPM or about 15 or 16 HP less than the 33-208-3 , but the simulation says my torque curve is broader so I would be hard pressed to see much of a performance difference . I run 13.5 to 13.6 at 104 to 105 in the quarter with street tires, closed exhaust ,4 spd,2 1/4 exhaust and tri-y headers and 3:89-1 gears.
So with the CompCam with a similar combo you might run low 13s but unless you use slicks or drag radials and large tube headers you probably won't get into the 12s but you get close and the 33-208-3 will probably be a nice all around cam with a good idle and broad power curve.
If you do some head work with a good exhaust, a 2500-2800 stall converter and a 3:70 to 3:90-1 rear gear you probably would get into the 12s.
Hope this helps.Bottom line is the 33-208-3 looks like a good pick. |
