Are u doing ur own modding of the 5.3 harness?...ive been researching this kinda swap for a while and i havent seen this many wires yet..lol

 

can you take a picture and post it of what you trimmed so i can get an idea? your working fast on this project, ive been working on my ls swap in my 1982 c10 for about 6 months and still not done. im getting close though i only need exhaust, harness, and a tune.

 

thanks man...appreciate it....

 

yes im wiring the truck wiring into the 5.3 fusebox. there shouldnt be a whole lot of wires to run. ive been gathering parts for this swap for quite a while. plus ive done this kind of swap before to my 79c10. but that truck was way more complicated! heres a coulpe of pics of it....

 

blklime02, i looked at the headers and there is no tag or # on them. i would look up other headers (like hooker or hedman) and see if my year an your year are compatable

 

the headers look like they fit good. can you take a picture of how close the header collectors are next to the frame rails underneath? you mentioned you had to trim the header flange, i would like to see how much. to get an idea. if they fit pretty well ill order them thank in advanced

 

I may be starting this swap in the next couple of months myself, nice to read up on some info!

 

nice work for sure

 

looking real nice!!

 

alright, more pics.......

here, i mounted the pcm& fuseblock


i ended up mounting the data link under the cd player.


here, for trans cooler lines i used lines from napa that dont require a tubing bender! too easy.


i am using a shifter linkage coversion kit from lokar because the stock shifter linkage hits the top of my header.


this is for guys keeping the old th350&400. its give the vss a signal. without it your pcm would never get out of its idle tables. this sensor tells the pcm the truck is moving! it also allows me to retain the stock speedometer cable.
