manifold will bolt up along with all other accessories, it's just a simple swap - you need the flexplate off of your 4.8L to match up to the tranny (out of a 2500 it should have previously been mounted to a 4L80e, LQ9 you would have to do this b/c it would have been mounted to a 4L65e). EGR is extra weight, just be sure to have it turned off in the tune.

 

OOPS!!! SOrry for the misinformation !!!!!!

 

01s had iron heads too, correct?

 

Should be able to see the alum. head in this shot.

 

I think only 99-00 LQ4s had iron heads.

 

lol, thanks for the correction. i thought the irons ran into 01. guess not though.

Great info! Thanks

 

didn't the crank switch midway through 01? IMO, just get a stock 80e and do it at the same time because your going to need it soon anyway.

 

She's in da hole!

 

What happen about getting some base times with the 4.8L. haha

 

haha holy crap dude you didnt waste anytime, how long have you had that truck like a week? thats awesome
