also most fbodys that run high gears have a 6 speed..also id get a better cam than that..if your gonna go through the trouble of changing your cam, get somethin worth your time of changing it

 

what cam do u suggest? i wouldnt pay more than $100 for ls6 cam and springs. id use the rest of the money to get a ls6 intake.

 

for the gear your going to run a tr224 with .563 lift would go nice..i used .570 ls6 springs with my tr224 i had..you can find one used for 200-275

 

Like Dirt track said about the gear comparo with the 6 speed.... Do you have an automatic or 5 speed. If automatic a stall would be needed and if 5 speed (they have either a 3.82 or 4.02 first gear) then your gear doesn't need to go to extreme. with a 5 speed I go no more than a 4.30 or 4.56, if an automatic no more than a 4.56 or 4.30.

 

how much more powah with tr224 over ls6 cam?

 

The tr224 would be a very aggressive cam for a 4.8; but so would the 5.13's. It would be an agressive idle but you would also have to have the stall and/or gear for it.
Not to mention lots of custom tuning.

 

iknow bout the .5 od of 6speed.

the truck is heavyier with less cubes

 

do you have an automatic or 5 speed? and what year? Makes a big difference on gear and cam selections.

 

i think he said he was getting a 2800 stall..this with a 5.13 gear a tr224 woud be ok

 

its auto
