1968 C10 5.3 swap, the easy way. - Page 3 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

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!

mcmlxix · 06-15-2012, 12:29 AM

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.

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

Cuate · 11-24-2014, 03:05 PM

I installed dirty dingo adjustable plates on 2001 5.3 motor .I had to remove the AC compressor to be able to bolt plate up to the motor. Is there something I can do do be able to bolt AC bracket and compressor back on same location and keep the adjustable motor mount plates? I'm getting ready to install on 1968 chevy truck and I really want to keep the 5.3 original AC compressor. Any help will be appreciated.

vannatta20 · 07-13-2012, 08:56 AM

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.

chuckmc8 · 10-01-2012, 12:18 PM

any updates?

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

eagleuh1 · 10-02-2012, 04:45 PM

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

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.

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

eagleuh1 · 10-02-2012, 06:45 PM

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.

vannatta20 · 10-05-2012, 06:48 PM

Drove 200 Miles yesterday and got 19.5 mpg. Thats awesome as I was driving 75 mph the entire time.
