If i was to swap the the 5.3 what should I switch it to 6.0 or maybe vette motor. All suggestins are welcomed

 

I say LS1. Some vote HO 6.0 Cant lose either way. I like the aluminum block because i'm a sand box warrior.

 

I have herad you can get a complete zo6 motor comp and all for like 5500 buck so i think that is a deal i would do that

I went with an LS1 for the weight savings.

 

I also am a fan of the ls1.... It's a blast to drive

 

Wouldnt you have to change the PCM and all the wiring to put a LS1/LS6 in a truck ?

 

You should but you can drive it with the truck pcm.... I am still driving on my truck pcm.

 

Yeah it works well my only opt out from the ls1 is that its still geared to run like a car so it pulls more at the top end than it does at the bottom. since you have a truck the wieght diff is huge so you might want to switch the cam or something so you can get some low end torque back

 

Nope...I still have the truck intake and all of the accessories, so there was no wiring changes at all. All you're really doing is changing out the long block--the intake, accessories, exhaust, etc all bolt up to the aluminum block.

And, the 5.7 has PLENTY of torque down low. Compared to a 4.8 it feels like a big block! I put a TR224 cam in mine and it feels NICE!

 

I can get you a crate LS1 for $2850 or so + ship
