LSx into thirdgen

[1bad83ta]

Hey guys it has been a while,

I have just bought a 03 5.3L engine and I will be transplanting it into the T/A. There are some fuzzy areas for me so far that I need help with if anybody has any ideas or places to look help me out. One fuzzy area I have is the headers, I don't want to spend 800 bux on a set. Does anyone know of any alternatives? I am still looking at torque converters to hook the 700 up to the engine and I am talking with Cohn racing right now on some alternatives.

James, how is the clearance between the hood and the top of the motor for you? I am trying to decide if the truck accessories are going to fit underneath my cowl hood or not.

Hopefully I will be on more often through this process.

James, Oh James, Calling James.............

custom made headers?? have you checked out thirdgen.org? they have some good wright ups there

A 5.3 isnt an LS1, im guessing that was just a mis type on your part, either way im staying tuned in, I like projects like this!

[lozanoa11]

its still a ls based engine

the 5.3 has a slightly smaller bore but that is it. On another note I guess, can someone change the title to LSx if its that important. Also I guess I will be looking for the camaro/bird oil pan and pickup as the writeups I have seen so far indicate that it does not fit.

Don't do it, it doesn't work. Cease and desist.

I have lots of hood clearance with the f-body set-up.....but I am not familar with the truck accesories so I'm not sure how far they stick up. If you need me to take any measurements for you, just let me know Justin.

Sounds like a good project. Have fun and keep us updated.

Wouldn't F-body or other accessories bolt up?

i think the biggest problem is gunna be the tall ass intake. mabey a big cowl hood would fix the problem?

[kammi10]

he has a cowl hood already if i do recall correctly.. good luck with it justin keep us updated and for crying out loud get on here more often

Personally, I'd just get a LS6 intake or something.

The engine sits pretty low, or it should, not sure if it'd be a problem...

He could do a lot of things with money, Justin is NOT looking to spend anymore than he has to on this project. I could help him out with a 4.6 Sohc swap.. hehehehe

Im looking at doing the same thing in my Camaro. Mainly bc you can get a 5.3 a lot cheaper than a LS1. But i have done some looking around and I found this guy that did the swap in his 89 camaro on thirdgen.org. Here is the link, i hope this helps you out.
