I used the Kugel linkage for the trans. A previous post shows a pic and the length to cut it. It doesn't even hit the header on that side.

John and Speartech says that the DOD will function and is not an issue. He is making my harness and setting up the computer for me.

Nice build, errhhh I meant update, .

[67C10BUB]

This is what I am doing for the fuel pressure gauge. Since I am running -6 AN for the fuel lines I put on a Russel P#670340 to screw a Summit 100psi gauge in to.

[67C10BUB]

I also thought that I would mention that my hose shop couldn't get me the metric O-ring fitting for the power steering pump, but I found that Russel P#648060 is an adaptor that will make this into a -6 AN male fitting, which he could make a hose for.

This is what I stumbled across for the valve cover breather line. You just drill a hole in your intake tube, insert the grommet and press in the elbow. Then I can just hook up the 3/8" breather line to it.

I'd run it thru a catch can 1st. These LSx motors have a history of sucking oil residue right past the pcv and into the intake tract.

I read thru a lot of debate on this and decided that if it's good enough for factory, then it's good enough for me. Thanks for your input though. If anyone has any other suggestions on how to make this swap better/easier I'm all ears (or eyes in this case).

its like that pay me now or pay me later saying....you'll have to deal with it one way or the other. Leave it like "factory" and you'll be cleaning the throttle body every 15-30k depending on use, with possible injector cleaning needs as well....like I've had to do with my '99 T/A (LS1), '01 Sierra C3 (LQ4), '04 Yukon (LM7), and '06 TBSS (LS2). My '08 LY6 (LQ4/L92 hybrid) is carb'd but will still have a catch can.

Awesome build..

[67C10BUB]

When I posted pics of my ac compressor it was brought to my attention that I am going to have ac line clearance issues, so I notched the flared portion of the frame as seen here.

[67C10BUB]

This is what I have done for my oil pressure gauge. I drilled and tapped the oil cooler take-off cover for 1/8-28 NPT and screwed the sender right in.

[67C10BUB]

This is where I was told to put my water temp sender, but it is metric. Everyone said that it was 12mm, but nobody ever said the thread pitch (that I could find anyway), so I bought M12x1, but it was a bad guess. What you need is a M12x1.5 to 1/8"NPT adapter. This is Auto Meter part# ATM-2277. Hopefully all of these specifics will help someone else to not make the same mistakes I have.

Yes it will. Thank you.

I am doing the edelbrock carb/MSD controller conversion.

Q1: on the power steering, did you have the adapter/converter at the old steering box end, or at the new pump end of the hose?

Q2: What kind of motor mount adapter did you use? The one I got does not allow my AC pump to be on.

Q3: where is the water temp sensor? Is that the bolt right behind the header tube on the head?


Im sure I will have other questions. Thanks again.

Yes, the temp sensor goes right where that bolt sticking out is.
I ended up buying a new 12mm sender from classic instruments, after spending days looking for a 12mm to 1/8 pipe adapter ( to the best of my knowledge there inst one)and/or a any OEM sender that would work. as far as the oil pressure sender I just hogged out a Stock one and tapped the inside to 1/8 pipe works great.

[breeze85cten]

I have been doing the same swap into an 85 c10. Just wondering what your plans are for the engine harness?

I'm going with Speartech. I'll post pics when I get it from him. He says 2-3 weeks. Hopefully he's right. I am anxious to get this thing rolling. The only thing that's stopping me is waiting for the harness (Speartech), the fuel tank (Boyd), and the electric fans (123 auto).

The Auto Meter part # ATM-2277 is that exact adaptor, M12x1.5. Buy that and the temp sending unit will screw right in.

A1: The adapter mentioned goes into the power steering pump on the 5.3.

A2: I used the ECE mounting system. Look back at page 1 and you can see pics. The trans ECE X-member just bolted right into place too, with no drilling.

A3: Yup, on the passenger side.

[67C10BUB]

This was a major find for me. I couldn't figure out how to hook up the power brake booster hose from the 5.3 to the '67 booster, since the hose on the 5.3 is 1/2" and the '67 check valve port is 3/8". This is GM part# 15823207 and it fits right into the '67 booster. It even comes with a new grommet. SWEET!!!

[67C10BUB]

I also got this engine cover to dress it up a bit. I think it looks tough. It is GM part# 12625893.

how did you find this engine cover? did it come on a gm production vehicle? how much was it?

also, what brand and tire size are on your truck? it all looks good!

thanks, jake

It was the same one that was on my 2008 Tahoe. I liked the way it looked on there, so I just went with that. I think it was around $60 from the stealership.

They are 295/50-15 Futura Super Sport GLS tires. I don't like them myself, so when I get my 20's I'll be selling these. I'll let you know. I'll make you a great deal on the set.

What radiator hoses did you use? I have a 71 chev C-10 and am installing a 2001 5.3 out of a GMC Suburban and the GMC Suburban hoses are too small for the 71 Radiator fittings?

I used the factory 5.3 hoses. They will slide on with a little silicone spray. I know they are a little small, but they seem fine once attached. You will have to trim the lower one down so it doesn't kink.

[67C10BUB]

I am using the 2008 Silverado power cables. Seems like a nice setup, but I am having a hard time finding a battery. I am told that the 2008 battery is a deign all its own. Anyone tried hooking this up to an Optima Red Top? I was told it wouldn't work at Costco, but it looks like it would.
