you could also run the fbody top end to move the engine higher. the wiring is all different for the fbody stuff but IMO much easier to work with.
Also costs more as well
 
Vince, thanks I'll keep you in mind.

With regards to the intake, I am pretty set on keeping the truck engine configuration. The initial cost savings over a car setup are significant. Conversly there aren't any material benefits that justify that significant price difference for this application in my opinion. One could always use a car engine or swap a car intake if they prefer the look or want additional clearance for some reason.
 
I am aware of California's reputation for being ridiculous. I'm a bit concerned about succeeding in CA because of the various components needing to be CARB legal. My biggest area of concern will be the exhaust since it will be more or less custom. I don't think I will have the volume to warrant submission for CARB certification, but we will see!

One thing to note, is that my swap and kit will revolve around the late model Gen IV engines and the 6L80. I have no intentions at this time of doing anything 4L60 related. I just think the 6L80 has so much potential and really lends itself to this swap due to its physical characteristics. They're also not that expensive if you stick to iron block truck 6.0's.
I think if your exhaust retains the factory cats you are ok...

Factory cats and O2 sensors all within 2" of there original position on the donor rig. This is up/down stream IN the exhaust system, not up/down/side to side for fitament in the new vehicle.

This whole thread gives me a boner, please try to incorporate CArb in your endeavors.

Makes sense since the computer is calibrated based on the relative temperature and o2 readings from the factory positions
 
I have been following this thread from the beginning. I am also very excited to see something like this come to market.

I have a question that I hope doesn't take us too far off topic. I know you are developing this plug and play for your 94, but how much different will it be to make it work in a 91 - 92? I actually love my 3fe, but if anything ever happens to it, I'm pretty sure I'm going back with some horsepower.

Paul, this is great info. Do you know of any guides or otherwise detailed info on what all is required for a "legal" swap in CA?

Is there a place to look up the dimensions the ref's will be using? I ask because the engine is from a 2008 Cadillac Escalade, but the exhaust I'm using for the manifolds/cats are the stock parts from a 2011 Cadillac CTS-V. Based on how they fit, I should be able to meet the +/- 2" rule with the CTS-V's downpipes/cats. They really just need some tweaking of the flange angles and for the exit on the passenger side to kick up to clear the driveshaft. I'm wondering how they will judge this configuration(Escalade vs CTS-V). In other words how will they determine what year/model vehicle to judge off of. The engine block is the same in both applications, but the intake/accessories/etc are different.

To be 100% honest, I have no idea. I have never been in/around a 3FE 80, so I can't really say for sure what the differences would be. I can't imagine that they are THAT different in terms of the dash/sensor wiring, but won't know until I have time to work through the 93-94 and 95-97 EWD's and then compare that info to the 91-92s. I'm not ruling them out by any means, but they will admittedly be last on my priority list of the 3 generations of 80's.
 
If you're using "factory" manifolds and the cats appear to be in the factory location, 9 out of 10 referees will not measure or look twice at them.
 
Subscribed...... and drooling....
 
where the potential issue can arise is not from the the ref dinging you on the location of the cats but rather getting burned by the PCM itself when it's scanned by the ref. It sets it's emissions readiness monitors to 'ready' when it can successfully complete a drive cycle. If the drive cycle can't run to completion due to an issue with say - cat temp not hot enough due to incorrect placement in the exhaust stream - then the readiness monitor will never set to ready and the ref will fail you when they scan the PCM through the OBD2 port. It's a load of fun and was the one thing that really caused me a lot of grief when I went to get my cert. I spent a lot of time researching about OBD2 drive cycles and bought an expensive scanner that would allow me to see the settings while driving the truck. There's all a documented process for a method of driving the truck to do the drive cycle. Honestly it's a pain in the ashtola.
 
LS edit will take care of any readiness test issues as you can set them all completed on key on.
 
I'll repeat what I've already said: I have a rig, actually two, in California, that want to do this swap. I am pretty much squared away to move forward on this if you want a partner in CA to mirror what your doing and go through the actual process. I think piggybacking here in Cali at the same time as you r&d out east would be beneficial to you.... :shrug:
Edit: one thing I want to do though is try to use the doubler that's in development rather than the marks adapter...
