new motor time

[Richardman1992]

is your truck a 2wd or 4x4? there are lots of 2wd guys on pt.net that have 6.0's or 370's (6.0 bored .30 over) and run in high teens-low 20's on the highway. you have an 05 so i would look for an 05 lq4 out of an hd truck. these have the upgraded connecting rod pins. you can reuse the front accessories and intake off your 4.8 in the 6.0. with the 317 heads and dished pistons that the lq4 has, you dont need to run premium, although the performance advantage of tuning for it is worth the offset cost in gas IMO. you will of course need to retune the pcm to take advantage of the engine swap. i would recommend blackbear time and time again as he is who i have gone with. if you want to swap cams, now is the time. id recommend something in the 210-220 duration range to keep lowend torque. valve springs and pushrods will also need to be replaced to support the cam. if you have any other questions, just pm me, i can help. Mods, if i cant post the name of another forum on here, let me know and ill gladly remove it from my posts.
