'68 C10 Short-Step 6.0 + TT swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

SCIV · 11-07-2008, 06:23 PM

Well, I thought I would give this a shot here. I am going to do this the lazy way since I already had a thread going elsewhere. I hope it isn't bad to link outside of here???

Anyway, I started with a bone stock 86,xxx mile 1968 short step side. Originally with a 6 and 3 OTT.

I have (with the help of friends) swapped in a 2003 LQ4 6.0L with 4L80e trans. Currently working out the parts for a twin turbo setup (ordered a custom cam this week). Once that gets here, I will start building it back up.

Eventually it will get a disc conversion with a 2.5"/4" drop, 3.73 gears with locker, and a little boost

Here is a link to the thread, and I will start to update here too:
http://www.ls1truck.com/forums/lsx-t...-6-0-swap.html

I am open to advice, comments & suggestions!
Thanks,
SCIV

Welcome from NM! Great looking project.

SCIV · 12-22-2008, 06:42 PM

Finally an update. After much debating, I decided to change out the old oil pump for a Texas Speed ported & polished LS6 unit as well as upgrade to an LS2 timing chain. I didn't have the patience to pull the motor, so I tried to do it in the truck. That ended up taking me 2 weekends since I cut the oil tube oring on the first try.

Anyway, got that done, and also changed out the valve springs for Comp 918's with TI retainers & hardened pushrods. Starting to look like a motor again. here are some pics of the progress:

New oil pump & timing chain:

New valley plate & knock sensors:

New springs & retainers:

All buttoned up (mostly!):

And new goodies from Santa!!:

Absolutely. Where? I don't know yet, but probably to the back of the block above the trans.

LuckyHenriksen · 12-23-2008, 12:59 PM

Thats sick man, I cant wait to see it with twins! I have the same swap planned for my '68. What turbos are you thinking?

Leaning towards 62 or 67mm. Eventually I will build a forged 370 for it, and really turn up the heat!

LuckyHenriksen · 12-23-2008, 01:13 PM

Sounds like a good plan

LuckyHenriksen · 12-23-2008, 01:15 PM

What kind of power are looking for on the stock long block? What heads are you running?

SCIV · 12-23-2008, 01:29 PM

317's with Comp 918 springs & TI retainers.

I think 600 hp or so is a good starting point.

That is the plan!!

Well, long term anyway. I am just trying to get it going by February 15th, so I can make a GM Truck track day in San Antonio. It will probably be on just motor, and the twins will start after that.

SCOTI · 12-24-2008, 09:49 PM

Subscribed. Nice work (except for cleaning the motor

).

I thought I cleaned it a little!

Here are some fuel system updates:

I am not sure on the angle of the filter, I have a 90* fitting on the way to mock it up that way to see which I like better.

Rokcrln · 12-30-2008, 12:32 PM

Looks good! I am toying with doing a small turbo set up on my 4dr Tahoe build with a 2005 5.3l. So why is your fuel pump set up so low?

ripdog28 · 12-30-2008, 03:11 PM

Love the build. I got scared for you when i seen how that fuel pump was mounted. Just looks iffy. IMO lift it up flush with the bottom of the tank or mount low right to the frame. I would not have it dangling below the bumper and frame all out in the open. it may get caught on something or hit. with the pricks today it would be easy for someone to cut it off and take it. may be fine but just gave me the shivers when i seen it.

I agree, it looks a little flimsy. Nice setup though!

SCIV · 12-30-2008, 06:33 PM

I was worried too until I mocked it up. Those are 1/4 plate, and it is stiff as a board.

The pump has to be below the outlet of the cell, and the cell is under the bed, so that is why it is so low. It is still 3" above the bottom of the differential case, so it isn't the lowest thing on the truck.

I would have to raise the cell to inside the bed to make the pump tuck under the bumper.

Rock* ME *Hardplace

LuckyHenriksen · 12-30-2008, 07:04 PM

is that how it is for any fuel cell?

ripdog28 · 12-30-2008, 10:51 PM

You should have an Electric fuel pump mounted at the level of the tank. Some want it lower then so the fuel will flow out of the tank into the pump eliminating the pump starving. It is not needed if you keep more then 1/4 tank and the pump is not above the tank just needs to be at fuel level.

SCIV · 12-31-2008, 11:01 AM

Maybe I took the Aeromotive directions too seriously? I have it mounted below the outlet on the cell by about 1 1/2".

So ripdog, you think I can move it up a couple inches to be at the bottom of the cell level? I just don't want to starve the engine or burnup the pump!

EDIT:
Just got off the phone with Aeromotive, and they said I can move the pump up to be even with the bottom of the cell. That will gain me 3-4" at a minimum. Thanks for catching that guys.

SCIV · 12-31-2008, 08:10 PM

I will work more on the fuel system tomorrow. Here is what I started tonight:
