Changing the gears and installing a performance tune will produce the most noticable gains.
You can burn hundreds of dollars and many hours on headers, exhaust, TB, 14x3, 1.7RR and etc but the gains are minimal compared to the gears and tune.

 

Iceman what do u mean by stroke it out? i never heard that before. i have heard of bore it out. but anyway i did tune the truck up about 4 months ago after i put the lift and tires on. i have upgraded the intake by putting on a AEM brute fore cold air intake and i would really like to leave my exhaust alone since that is my favorite part of the truck. but like u were sayin iceman i want a truck that can go anywhere but i want it to have some good speed at least so i can keep up with other trucks seein as i aint exactly gonna be racin a vett. i just want to smoke my buddies in a race. so the 4.56 seems like what people sayin i should get. i not sure what in the world purpledodge is talkin bout. when someone pulls up to me on the street revin the engine i sure not gonna back down lol

 

Grow up. Now I'm glad you have a slow truck.

 

Stroke the motor is when you bore the motor and put in a bigger crank. It gives you a longer stroke. It turns a 318 into a 390.

 

Fixed it for ya!

 

Thanks I have a hard time typing at night

 

i love my 4.56's....i run around 1800 rpm at 60mph......and when i do a 37 inch tire, i will be fine.

 

y would it be a time bomb

 

Because as a 318 it is pretty reliable, but stroked to 390 the temptation to run the **** out of it will be greater than that block's ability to withstand the stress.

 

When you stroke a motor you are decreasing the reliability of the motor because there is more stress on it.

For that mater in reality when you do any upgrade you trade performance for reliability.

Take my truck for instance. I just got finished installing the headers and it seems like one quirk after another. The vehicles from the manufacture are designed to see a wide range of driving conditions, and driving types. When you modify an enigne you are changeing it to meet your needs not necsessarily what the vehicle will actually see. It also seems to me that when you have small problems with a modified vehicle it more likely to cause down time as compared to a stock vehicle with the same problem.
