Vortec 5.3 install on my 84 C10

[Skyshadow]

The truck will be tagged in Oklahoma so i dont have to worry about it but as for helping you, two things you can do. Hook it up proper with the O2s working, evap and such and hope it passes or do what i did with my 400whp race spec Evlolution 9, pay a place off to "pass" your truck. only cost me double normal price.

Sorry its been so long guys. I ran into so serious life hiccups, But I'm back up and running now. Since November I've have got the vortec dropped into my truck with the trans hooked up and seated in the cross member. I also have the body panels and bed all put back together. I have swapped the stock body mounts with Urethane and bought a beer keg for the gas tank.
What I have left is a hefty list that i plan of tackling soon, now that I'm back on my feet.
-ECU reprogram
-Wire the new motor into the existing ignition
-Build a fuel delivery system
-Exhaust system
-Last, Road worthy details such as ball joints, tires and shocks

I'll post everything as i get it done.

My stock throttle cable is about a foot too short. Anyone know a easy fix? Aside from swaping to a uni cable

Get one for the donor truck.

^ I'm guessing a donor 05?

[Captkaos]

Well, no.  In 2003 everything went to drive by wire, so you need one from a 1999-2002.  I can't find my pictures anywhere and my truck is at the shop, but the 73-87 have a square hole with 2 tabs, just cut down the 99-02 to match.

Ok I got the new cable, went in easy.  I see what your talking about with the tab. It doesn't sit in right so the pedal barely pulled the throttle open. What did you cut back? I'm thinking of bending my pedal fulcrum til it become tight on the cable. Should work right?

My grandpa tried to be cool I guess cause he needed to move my truck. So he broke the steering wheel lock... I have a donor steering column but it doesn't have tilt. I would like to just pull the parts I need from it and keep my tilt columm.Any one have any insight on this?


Also I would love to know the exact in and outs of my water pump. I know the four connections are feed and return and heater core by whicj one is feed and which is return

Found out today that no stock exhaust mani is going to fit between the frame and motor. Guessing I'll have to buy some slim headers.

[Captkaos]

The 2 smaller ones are obviously Heater core.  They are the same size as yours so just hook them up directly from there to the heater core.
If you are using the factory radiator from the truck the top hose goes to the drivers side top opening, the bottom one goes to the bottom passenger side.

You can see the top one here:



What manifolds are you using?  F-body manifolds will fit in the framerails, including the 2010 version


On the column the pieces you are missing are tilt specific.

I want to do this as well to mine but as long as i get 8 cylinder in it i will be happy. I got an inline 6 right now:(

I'm installing a all aluminum radiator for a 05 5.3... would it still be hooked up like that?

I'm using the mani that came with the 5.3. Needs like a inch more to clear. Even went to the scrap yard and got mani's that came off a 05 5.3 without the bulge in the casting from the old egr outlet, still wouldn't fit. Just going with headers, any suggestions? Such as long tube, short tube.. etc

[Skyshadow]

Been looking into F body exhaust manifolds. Things are hard to find! I found a pair for $150 but I can get Fbody long tube headers for $180. Thoughts? I'm not sure the long tube headers will fit the firewall curve of my truck.

Missed this, in the square hole where it locks into the firewall I trimmed it so it would stay locked.
For the pedal, I bent it to get full travel out of it...  Look here:

If you are looking for longtube headers get the hooker super comp 64-72 el Camino ls swap headers.  Flamingbig10 has them on his truck, pics here: http://forum.73-87chevytrucks.com/smforum/index.php/topic,10766.msg162492.html#msg162492

Your gradfather needed to move your truck so this was his solution? Why not ask you for the key?
