Where is a good web site to look at the mods for the 5.3 GMC sierra trucks

 

engine. the body looks good already, its got flares and steps and all that good stuff

 

Well there are quite a few people on here with lots of mods, look at some of the past posts.
The admins here like fast4.8 oxidzr and several others know these engines well. Most things that help out a ls1 based fbod or vette will work, since it is basically the same engine (iron block though, and better intake and a few cubes smaller).

 

What kind of mods? Body, engine or both.

Some of our site sponsors like Tbyrne, Yank (for converters) and Thunder Racing have a selection of truck parts. MTI also has truck parts although not on the website yet. Tbyrne has a few trucks and things that Tom himself has modded extensivly. You can check my site (in the sig link) and the picturetrail link there to see my mods.
