i have a 06 3.5 colorado and have recently found that 08 will come with a 5.3. I have been wanting to to put a ls series v8 in my truck. i know people have already done it and i am wondering what modifications where done concerning mounts, drive train, if my stock computer is programable for that and if there is anything else i need to know. Does anybody have any experince, or real knowledge about that. Please no guesses

 

Check out current performance. They have mounts and wiring harness. You will need the computer from the donor car/truck. The rear end isn't the greatest, but it hasn't really been tested that much. The trans is a 4L60E but has a different bellhousing and input shaft, you can either swap those or the whole tranny.

Thats about it. Pretty simple now that the mounts and harnesses are available.

you will also need headers which some people sell.

 

nobody sells headers for the colorado V8 swap. current performance has been using stock manifolds for their swaps.

 

thanks, i was thinking that i could buy o.e.m mounts for the 08 v8 colorado setup but im not sure if the actual mounting to the vehicle are different. If anyone knows anymore companies playing with this let me know

 

wont really know until it comes out.

 

Why not just wait until the 08 comes out and buy one of those...might be more cost effective.

 

and it will no doubt have a stronger rear end.

 

i dont know ill probly wait to it comes out and see how much they want and what they will offer me for mine, but i would rather build a ls2 to put in it then to pull the 5.3 and build it.

 

Their was company, you can google thier website but I think they went out of business, they are no longer on ebay nor does thier website work.

ls1performanceparts. com was the wesbite.
