Re: 1968 C10 5.3 swap, the easy way.
 

I used R134 from the part stores. Guess what I got from the salvage yard to 60$... Power steering box off an 80's GM truck and hydroboost off a 2004 GM HD pickup:) Cant wait to install that next. Just need time off from work!

Re: 1968 C10 5.3 swap, the easy way.
 

CaptainFab make a nice bracket to mount the hydroboost. I have the boost from an 05 GMC and I used the flat plate from an AstoVan (or CaptainFab has one). I havent figured how to connect the pedal to the hydroboost rod, but my thought was to cut the very end off and thread it to 3/8" and use a coupler and a heim at the pedal...

How I kept it simple. Used dirty dingo adjustable mounts for mid to late 80's GM trucks. They have 2 inchs foward and back adjustability. Next I got frame mounts for free from the same era of trucks.

The engine mount on the left is the factory inline 6. The mount on the right is a late 70's clam style mount.[/quote]

May I have some clarification on the parts used for engine mounts? In addition to the use of the Dirty Dingo mounts. Did you use the factory (68-72) inline 6 engine mount on the left and the late 70's (73-87) V8 clam style mount on the right to allow for the factory Gen III A/C compressor to be retained in the stock location? This would help those trying to retain the factory A/C.

I used Both frame mounts from the 73-87 trucks. Ac compressor fits great.

Do you have any pictures of the 73-87 frame mounts bolted in place?

Re: 1968 C10 5.3 swap, the easy way.
 

Well I have pics in this thread of the mounts mocked up. I used the orginal mounting holes and drilled a few extra. Its really easy. Once you have your engine mocked up in the frames rails it really easy to see what you will need to do. It was very easy to install the engine and i did by myself in my driveway. The hard part is having the fuel system setup properly fuel injection. My ideas havent worked out well fo me.

Re: 1968 C10 5.3 swap, the easy way.
 

any updates?

Re: 1968 C10 5.3 swap, the easy way.
 

What AC condensor did you use?

Re: 1968 C10 5.3 swap, the easy way.
 

tell me more about what you have determined works with the fuel system..

Re: 1968 C10 5.3 swap, the easy way.
 

I used a Boyd Welding aluminum tank with in tank pump. Used summit AN 90's coming out of tank and AN tube nuts with 3/8 aluminum tubing and summit AN to quick connect to connect to Corvette filter regulator. I mounted all this to top of tank. From filter/reg I used fuel repair tube from auto zone. Grazed on AN fitting and connected short section of braided stainless fuel line to 3/8 steel fuel line along frame rail. Used another 1 1/2 foot section of braided to connect to fuel rail on engine with russel fitting. Good luck. Jim

Re: 1968 C10 5.3 swap, the easy way.
 

I agree to use the boyd welding EFI tank. What I am going to to is use the non efi tank and cut a hole and drop in a LS1 Fuel pump assembly to save money and use the factory quick disconnects. I get the fuel pump ass. used off ebay for 50$. My intake has a built in FPR so I had to tun a return line back to the tank and ran a generic fuel filter in line that uses quick disconnects.

Re: 1968 C10 5.3 swap, the easy way.
 

Heres a vid of it. Its my daily driver now.

Re: 1968 C10 5.3 swap, the easy way.
 

Cool. Didn't see what year engine you used. I just got mine running on the Boyd tank about 2 weeks ago. Had been running with a frame mounted pump under driver seat. Took suction from in cab tank with a return from the filter regulator run back to a modified stock sending unit. Kept getting pressure buildup in tank and fumes in cab. Guessing from fuel heating up. New o-ring in sending unit didn't fix it. Like that your AC runs cold. Will be swapping out my condensor when get done with my current job. Appriciate that link.

Any more changes, updates or "issues"!!
Thanks for the detailed build.

Re: 1968 C10 5.3 swap, the easy way.
 

Awesome! I got my lq4 couple of weeks ago...my t56 came in on Monday. I wanted to see if you like the dirty dingo mounts, and do they work with what is on the frame now, or what else do I need? Would you mind posting the link of the ones you got? I noticed that their site does not really show one for just 67-72 trucks.

Also, what intake did you use?

Re: 1968 C10 5.3 swap, the easy way.
 

I'll answer for him. You need the 73-87 factory truck frame to crossmember mounts and then order the 73-87 dingo mounts. Just got both for my swap and it's very straight forward.

Re: 1968 C10 5.3 swap, the easy way.
 

this is how I want my swap to be...nice and simple. im gonna use this as my inspiration for my 74. im just concerned about the wiring and fuel system.

Re: 1968 C10 5.3 swap, the easy way.
 

YES, those two items MUST be addressed, just throw more money at the problem, easy fix !!!

Re: 1968 C10 5.3 swap, the easy way.

Re: 1968 C10 5.3 swap, the easy way.

wow!!!! man i am inspired!

Re: 1968 C10 5.3 swap, the easy way.
 

We used the boyd welding carb tank and simply dropped in a LS1 fuel assembly I got off ebay for 50$:) It works great and was simple to do. The tank also came with a fuel sender so my fuel gauge will work properly now. My dad made the truck a short bed. I bought new bedsides to help with that and they shorted the frame. Found a deal on TTII rims in 18x8 and will be installing those shortly. The rest of the truck should be finished and assembled next week some time. We used a single stage paint.
