i have a 4.8 which is not good enought right now. im wanting to swap in a 6.0 either a lq4 or a lq9. but i wanna forge it for i can put the procharger i currently have and let it boost up to 15.
what am i going to need for the swap and what do yall guys recomend.
will my 4l60e bolt up to it.. i dont wanna get rid of it cuz its a stage 3 tranny fully built . but i need some help on what all am i going to need for the swap and if the tranny is going to bolt up against it and where can i get the forge pistons..

 

the trans will bolt up (if the crank is an 02+) but I can take a wild guess and say it wont last. Do a search on forge pistons for the 4.000" bore.

the swap will bolt right in, harness and everything. You will need a 6.0 tune flashed in to the PCM and then start from there.

 

what do u think wont last

 

Pistons. 15 psi+stock pistons=

 

the pistons should be fine.. if the timing is conservative.. but the trans prolly wont be too enthused about the new found power..

how about a lil more info on your truck.. all we know is it has a 4.8..
