Cam Shaft Help

[bronco9588]

I know that it is extremely hard to get what you want for a camshaft on a forum. I will call comp cams and see what they think of my application. However, I am curious about stall speeds. I have a 440 and i am looking at the XR274HR-10 roller lifter cam shaft.

The description "HYDRAULIC ROLLER-3.55-4.10 gear, 2000 stall in 440,2200+ in 383, 9:1 compression, high performance street." How do I interpret stall numbers if my car is/ going to be a manual?

EZ you ignore them. You have a stick with a clutch so you can launch at whatever RPM you want.

Those numbers indicate the cam is fairly streetable IMHO.

Roller numbers are a little different to interpret than regular cam numbers. They seem more extreme than they are.

The stall recomendation still gives you an idea of how streetable it will be. 2000 rpm is not much of a stall converter. If the desired stall rating is too high than it will be a pig, even with a stick.

The problem with a stick is, that no matter what speed you rev the motor to while releasing the clutch, once it is released, the wheel speed has to match the motor speed(proportionately with the gear ratio)

It can cause a situation where the car sems to respond well, but then has a big bog in it, once you are finally off the clutch.

Definately worth a call to the manufacturer of the cam, I'd say. .02
