Default 1968 Camaro Build W/ Duramax

Hey guys!

I thought I would share my build and the progress for the next several months.

I'm placing an LMM Duramax in a 68 Camaro. I picked up the car about 6 years ago. I wanted to drive the car for a while before tearing it apart, but after some small electrical problems that exposed other issues with the car I decided to park it at start tearing into it. The Camaro sheet metal is in very bad shape. Unfortunately, the lack of time I have (4 kids that are into sports) I'm having a fabricator shop complete all the welding (sheet metal, exhaust, and etc.) on the car for me.

Engine: 08 LMM Engine (stock for now). I will place twins and bigger injectors in if I can find some for the right price.

Chassis: Roadster SPEC Chassis (9" FORD Readend)

Brakes: Baer Pro 14" 6 piston calipers on all four corners

Transmission: Animal Performance Beast 4L80E

I will upload pictures soon. I welcome any input and discussions.

Subd should be a real nice build when finished man.
https://www.duramaxdiesels.com/forum...ad.php?t=82543 here is a set of compounds for sale on here. Not sure how it would fit with your setup though. Most likely have to just buy the compounds and fab the rest up yourself.

I think we should have an enough room. My only concern is the downpipe. Clearing the frame might be an challenge, especially if the tubing is 5" diameter.

There is absolutely no need for a 5" downpipe or exhaust for that matter. Put what fits in your car, you'll save yourself tons of time and money. Make it look right for the car. You can always y the downpipe under the car to make it flow more with smaller piping. 4" split into 2 3" pipes will flow plently for these engines and make ton of power.

That's a really nice frame, wow. Looks good. Let me know if there is anything I can do to help, even if its just pointing you in a direction to look for stuff or what not to do. 10 years into my swap and I'm still figuring shit out.

Sick looking Chevelle! Yes I had an brain fart about the Down pipe size. 🙈 we havenít decided how we wanted to tackle the exhaust yet. Did you have to make custom motor mounts? What about the oil pan? Did you have to chop the height down?

Yes to both. Custom motor and frame mounts. And chopped a ton off both pans, upper/lower.

I was really hoping you'd chime in. How's your Camaro running?

Sounds good to me. I've read your build thread several times. You did an amazing job and the car looks sick! I'm sure I will have tons of questions when we get to the point of installing the engine.

I'm in the process of tearing down the engine to clean it up. I believe there's a small oil leak between the upper oil pan and timing cover. There also appears to be a leak between the upper and lower oil pan on both sides of the engine. Thoughts?

In addition, this engine has about 130k miles on it. Should I replace the water pump or any other items/sensors before putting it back together?

Thanks,
Joshua

I would do a water pump and EGR delete while itís out. Along with a LB7 up pipe.

When you have the pans off to modify them you will get to re-seal them then, yes they're leaking. I would remove the rear cover while you're at it and re-seal that as well. And what he ^^ said above. Maybe take a look at the turbo while you have it apart. Also, you can clean up the engine harness quite a bit, specially if you are moving the emission stuff. Not sure where you're located but deleting the gp circuit completely will clean up the engine too. A lot of people run their engine with them, every once in a while I'll have an issue but not that often and I always carry a jump pack with me so it's always started.

Runs great. Havenít had a single problem with it in the 6 or so years itís been running. Been contemplating lately about making it a dry sump... weíll see. Also want to install a vintage air kit in it someday.
