They did another exhaust fitting today: manifolds, CATs, O2 sensors all tack welded in their final positions. Everything fits. Nothing touches anything it shouldn't. Installation instructions followed to the T. Gonna pull it all for final welding, plug an extra hole or two in the new manifold, then put it all back in for good & connect it up to the rest of the (original) exhaust system. I'll upgrade the CAT back system later.

Very nice!!! I knew it was gonna be a race to which one of us would get our exhaust work done first.. Took me over a month, but it's well worth it.. You're gonna love that car when you can finally drive it..

Thanks.
It's even better the shop actually doing the swap has stuck with it. An LS swap is tricky enough without the added CA smog requirements that come with the EROD package, and a customer (me) who still wants the stock creature comforts like cruise control, AC, etc.
They keep plugging along and are getting awfully close.
After the exhaust system is finished up, some connector pins are on order for the tach/speedometer adapter wiring, the cruise control wiring has to be finished, and we're waiting for the kwik AC bracket to show up. There's also some question as to which intake/air filter to use---the one that comes with the EROD is pretty bulky---with the C6 style favored if it will fit.

I would guess the early C4's would have an easier time since the ECM does not control the gauges. I would also guess if you have an 85 like me, there would be no issue regarding ABS (I don't have that) or other computer controled problems since these ECM's are somewhat behind on 21st century technology.....having said that,
the big thing for me on this conversion would be to somehow have the upgraded, up to date computer controlled EFI to better accomodate tuning......these early EFI cars are getting long in the tooth and harder to find anyone to tune them if you are running modified engines.....LS tuners are a dime a dozen....also
it just seems these later archtecture powertrains have less oil leaks, are lighter, and respond all to well to upgrades.........the only downside I have with LS engines.......they just "AIN'T PRETTY"..........but I guess I could get over that pretty quickly with the enough HP!
I guess you can do whatever you want as long as you have the funds to throw at it, hugh??
again, I embrace this project like ch@os' ...awesome...would like to see an LS7 C4 out there too!!

We've talked about using the stock intake but aparently this would entail quite a necking down of the airflow so something bigger is preferred. Also, the installation instructions make me leary of using anything smaller:
Air Cleaner It is recommended that the provided dry element air
cleaner be used. However, if an alternative air cleaner is used it must
be of the dry element variety. NOTE: Emissions compliance and
fueling cannot be guaranteed if a different part is used.

I looked, but couldn't find seperate installation instructions for the LS7 EROD package.

Yup, that's it.. If you grab a C6 (LS7 preferred, but LS3 will work) Intake and filter it will have the bracket built in. Otherwise you can TIG weld the aluminum sensor bracket to any round aluminum tube and make your own intake tract.

This is an area I'm simply too far away to contribute & have to trust to their judgment. They have a variety of intakes on hand. I think the radiator orientation in the earlier C4's makes it harder to get the intake into the cold air region.

Oh, ok. I thought you were asking for advice/options on what intake to use...

The issue with the intake is fitment & since they are hundreds of miles away I can't look at it and put in my 2 cents. I believe Ch@0s' radiator is installed at an angle that helps with the intake routing, but mine is vertical. I forget what year yours is (though '85 seems a good guess) so if you're able to get the C6 intake to fit it seems lilely it will work in mine, and that's very encouraging.

had the same screen name for the past 20 years on dozens of forums..
But my Vette is a '92, so the angled radiator may be why the C6 intake fits.. sorry.

I have not looked at this thread in a while. Cannot believe your build is not completed after over 10 months! My build took just under 4.5 months and I thought that was way too long. I assume most of the extra time is a result of the Calif regulations. Hope you are driving it soon!!

I didn't want to jinx it, but...
was told last week he has all the parts needed, in-hand, for first start.
Exhaust done, a little wiring TBD for the Dakota adapters, still mulling over the air intake---will likely use Ch@0s's claw or suck engine compartment air (the C6 intake hit's the hood).
AC's a different matter, but I'm holding my breath expecting to hear it rumble soon.
Oh, and trust me, they want to wrap this up as badly as I do.

That's great news! I guess I was very lucky in a lot of ways. Kim Madsen who owned Corvette Restoration AZ was my builder and he personally did about 80% of the mechanical work on my car. The build was completed in July of 2010. Shortly after the completion, his cancer came back and he sadly passed away in May of 2011. Three months later his company went backrupt. My build was one of the last completed ones his shop had before he became too sick to continue working. Fortunately for me Wes, the gentleman from Florida that did the engineering and all the electrical work on my car, knows everything about the build and has become a good friend and my go-to guy with any questions I now have. The good news is that cars like ours are unique; the bad news is cars like ours are unique! Good luck!!
