i have heard if you put a pulley on your 5.3 liter it will add some power now is this true or just another fishin story? and if it is true where should i look for the pulley and some more info about geting one? thanks..

 

you want a underdrive crank pulley. most sponsors have them, make sure you get one for a truck. and you need two new belts. 5-10 hp

 

ok another question whats the deal with the corvette servos? those could be in my future purchases as well...

 

Search button will be your friend, only saying this because these questions get asked every week.

but im a nice guy and will answer your question.
The corvette servo increases the apply pressure on the 1-2 shift(makes it shift harder). Usually you will be able to chirp the tires shifting into second.
It is also better for the transmission, so it doesnt have to absorb so much energy when shifting, it just puts it to the ground

 

Pulleys don't make power. Engines do that. Underdrive pulleys just redirect wasted power to your wheels. The super servo kit is a good install for the 4L60E. You might as well do both the 1-2 and 3-4 apply pistons. That's two kits and you get a new billet cover in the process. The apply piston are billet too. If you're not an experienced mechanic you better leave this install to an expert. Getting the cover off once the large snap ring is removed is pretty tricky. Getting all the parts back in and getting the new cover "O" ring seated fully home can be a bear. I've done several of them and it take a lot of patience because the servo is hard to get to with the transmission in the truck.
