I want to replace the stock cam with one that provides better torque. I have 5 speed with 33" tires, stock 3.73 gears. I don't want to upgrade gears yet. Will a different cam make me happy?
When I
read this, I can see that a gear change is already planned.
The question is in regards to a different cam.
Having real world experience with a lightly modified 4.0L I can
honestly answer the actual question.
I've run this engine combination with 3.08's, 3.55's & 4.10's, all with 26" tall tires.
On the street, With the 4.10's anything more than 1/4 throttle in first results in tire smoke and a quick shift into second will keep it going. Even with the 3.55's a spirited launch has the same result. Now with the 3.08's (pretty close to 3.73's with 33's) and a soft launch there was more than enough torque to get moving quickly without even coming close to bogging the engine.
(With a 4x4 in low range, not an issue.)
I can honestly say that the 4.0L should have come with this cam in the first place!!
Now, since I drag race the truck, of course I run the 4.10's & slicks for traction, and I'll admit, gears with this combo will definitely keep you smiling for as long as you own the truck!!
