'67 5.3L Build Thread
 

Just thought I'd put up a build thread of my project. Hopefully it will be helpful to others, just as many on this forum have been for me. This isn't my first engine swap, but it is my first classic truck. I have been wanting a '67-'68 C-10 nearly all of my life, so I finally took the plunge, sold my 2008 2500HD Duramax and bought it. It is sooooo nice not having a $600/mo payment any more.

Anyway, this is what I started with...

Re: '67 5.3L Build Thread
 

Soon after I bought it I tore the front end off, sanded down the frame, and painted it semi-gloss black.

Re: '67 5.3L Build Thread
 

I went with the ECE engine mounts and trans cross-member. This is how the mounts look in the frame.

Re: '67 5.3L Build Thread
 

This is the motor I am going with. It is a 2008 5.3L with a 4L60E trans out of a Silverado. Looks pretty clean.

Re: '67 5.3L Build Thread
 

Thought some of you guys might like to see how the motor sits in the frame with the ECE mounts. I couldn't be happier. It looks like it was meant to go there. The trans cross member just bolted up in the factory location as well. This is where I am now, so I will post more when I make some progress.

Wow, nice truck! I'll definitely be watching this. What are you doing for a fuel tank?

Re: '67 5.3L Build Thread
 

Nice. On the blazer forum, a member does a nice frame mod to clear the a/c lines.
Looking forward to your progress!

Re: '67 5.3L Build Thread
 

Looks great. Im doing the same thing with a '99 5.3.
What headers are you going to use?
Are you going to use Air Cond?
Are you going to have your ECM reflashed so you can get around the VATS?

Re: '67 5.3L Build Thread
 

I bought an aluminum EFI tank from Boyd welding. It cost $591 shipped to my door because of a group buy right now. Pretty good deal. I'll take pics once it arrives.

Re: '67 5.3L Build Thread
 

I bought the Doug Thorley headers made just for this swap. They are $495 shipped. Good deal for such a nice header. I'll take pics when they arrive.
I am going to put in AC, but not the factory system. I think that I am going to go with the Old Air system.
I am going with Speartech for the wiring harness rework and ECM. It's a little pricey, but Shifty said that he was to do it over again he would just go with Speartech and save a lot of frustration. I read Shifty's build thread very thoroughly and learned a lot about the swap. THANKS SHIFTY IF YOU ARE OUT THERE!!!

Do you have a part number for these?

Re: '67 5.3L Build Thread
 

Nice ride!
But, I sure hope you don't have to get at the A/C pump for a L-O-N-G while!:censored:

Re: '67 5.3L Build Thread
 

Nice truck and great score on the 5.3. It has the 243 heads I see......those are the same heads as came on my LS2...and what also came on the LS6.

Re: '67 5.3L Build Thread
 

Okay first off very nice truck and engine swap you have going on.

But I have to ask everyone that has done this swap, it seems like an expensive swap with headers, motor mounts and ECM reprogrammed and what not.

The benefits seems to pay off once all the headaches and expensives are addressed.
As folks are saying they have better fuel mileage and driveabilities is increased as well.

Re: '67 5.3L Build Thread
 

you'd probably spend about as much money adding EFI to a sbc... as you would getting one transplanted and running in an older truck.

Re: '67 5.3L Build Thread
 

They are P# THY-324Y-C. They say that they will work with the truck spark plug wires in the instructions, but the don't. The front 2 on the passenger side can't even push on the plug. Guess I'll have to see what I can find. I'll post pics of the test install later.

Re: '67 5.3L Build Thread
 

This looks like a sweet addition to a sweet truck! I'll be watching ... thanks for the ride along!

Someone asked about the cost involved and the benefits derived. Right now Smeding Performance in Tejas has an intro deal on a 383 crate motors with efi for 5 large. The efi setup is Accel ... they are running this deal until the first 50 are gone ... it is a pretty good price for what you get. They are claiming about 22 mpg.

I have one in the works

Clean..in everyway

Re: '67 5.3L Build Thread
 

Beautiful truck that engine sits really nice Im also in the process of painting my frame good times...

Re: '67 5.3L Build Thread
 

:bo2: Nice project. Thanks for sharing.

Re: '67 5.3L Build Thread
 

Cool. Keep the pics coming.

Re: '67 5.3L Build Thread
 

What up Bub, Nice progress on ur C10, Good you got the TH324Y-C Headers
I use the MSD Ignition 8.5 Super Conductor 32829 and also a Lokar ED-5008 Flex Braided Stainless/Alum. oil dip stick both part #s work good with the headers.

I'll be waiting on your New gas tank pics.

:ito:

Re: '67 5.3L Build Thread
 

Gus,
Glad you found me. Thanks again for the info at the Truck Shop. I'll take any advise I can get. I'll have to check out those wires.

Re: '67 5.3L Build Thread
 

Here are the pics of the headers installed during the test fit. They fit SWEET!

Re: '67 5.3L Build Thread
 

Anyone have any input on how to run the trans cooler lines to the stock radiator. I am planning to cut off the fittings at the radiator and the trans, flare the ends of both and hose clamp some trans cooler rubber hoses in between. The only problem is, the lines are 3/8" at the trans and 5/16" at the radiator. If anyone has a better idea I'm all ears.

The pic is of the flared lines at the radiator.
