I am currently working on a project (in California... always fun for emissions) where I'm using a 2001 Corvette 5.7 motor (I believe it's an LS2) into a 1984 Jeep Grand Wagoneer. I have a few questions...

1) Since the oil pan on the corvette motor seems to be a dry sump system I will need to replace with something like a camaro pan that has a rear lower section to help avoid the front axle/housing. I would also need a new oil pump/pick up and screen as well and possibly a new dipstick. Does anyone know what to order?

2) Also, as you can see in the photos below that the used motor came with stock manifolds which don't exit far enough to the rear to clear the frame. They also have the O2 sensors in the downpipe before the collectors and an additional connection which I believe is a blow off for the exhaust for emissions... My question here is what shorty rear exiting header should I use and is CARB legal in CA? In addition can I ditch that crossover pipe once I get the new headers (which I'm guessing won't have the holes anyways) without having any code issues or emission issues?

Lastly, could I just add O2 sensors to the collectors below the headers or do the CARB legal headers typically have the bungs needed in the same location?


Thanks for any help on these questions, I am trying to figure this out before I can move forward on the project. I am using a 4L60E trans mated to the original TC and purchased the wiring harness, motor mounts and special adapters from Novak-Adapt who have been great to work with.

This helps regarding the recirculation circuit I asked about... may need to keep on motor.

Few things.

1. The 5.7 is an LS1. If its a Z06, it is the LS6. The LS2 is a 6.0.
2. Its not a dry sump.

So maybe I'm not clear. If it's not a dry sump is there still an external oil reservoir in the Corvettes, still requiring me to purchase a different oil pan which could hold all the oil since I won't have an external place to put it? The oil pan seems shallow and too small to hold the oil... thoughts? Or is this fine the way it is?

So yes, it would be a LS1 then. thanks!

Post a pic of the pan,as long as it clears what you need it to clear it should be fine,there is no dry sump or external oil tank on a Corvette until the 2006 7.0 Z06.

The C5 (1998 - 2004) Corvette pan is sometimes called a bat wing pan due to it's wide and flat shape. That pan is a wet sump design and rarely fits any other chassis without heavy modification.

As TFI Racing pointed out, the dry sump pan started with the Gen IV engine in the 2006 - 2013 LS7 Z06 (all 7.0L) and the 2010 - 2013 Grand Sport LS3 manual transmission only cars. I believe the fifth gen Camaro with the 7.0 also received the dry sump pan.

Having said that, all Gen III pans are interchangeable when coupled with the proper pickup tube and windage tray. Many Gen IV pans are also interchangeable with the same rules, with the potential exceptions being the dry sump pans (different oil pump, etc.) and the DOD / AFM stuff.

My experience, I use the pan that fits my chassis the best. Done. Being in a jeep, the Muscle Car Oil Pan kit may fit and not have problems. As always, you need to measure to be sure.

As pointed out, you have an LS6 with batwing pan (wet sump). That pan is designed to work with those exhaust manifolds and not much else.
I would suggest swapping out the pan for something that works in a GW.
As for exhaust, most will dump to the rear more than the Vette or GTO manifolds. Trucks dump out the back, 2010+ Camaros dump down at the rear cylinder. Look for pics online, see what will work. Yes, you can add an O2 sensor bung in the pipe below the manifold.

Thanks everyone, yes I have the bat wing!

I purchased the oil pan kit for the Camaro which should work well for my application.

I will look at downpipes as well. Maybe getting something OEM would help from a truck possibly as long as it would fit my 5.7. I'm guessing this would make it easier for fit and finish and also emissions.

If anyone has any ideas on the exhaust manifolds and what truck applications would work I will gladly take it. I will look into the truck options in the meantime.

Thanks,

Bryan,

My guess is that the engine is a LS1. If it was LS6, the head casting number will be 243. LS6 exhaust ports also have a distinct D shape with a flat bottom, while LS1 heads have more round exhaust ports.

Those exhaust manifolds are clearly C5 Corvette. The engine should also be DBW, as both LS1 and LS6 Corvettes used it.

For manifolds, you may want to look at the C6 Corvette manifolds. They dump in the center but are much shorter than the C5 manifolds.

Andrew, thank you. Yes it is a LS1. It was from an 01' Vette. When you mention drive by wire that I also something I've changed. I went to a camaro computer and throttle body so it is by cable now and Novak Adapt altered and reconfigured my wiring harness to fit this motor and jeep.

I will have a look at those manifolds you mentioned. I should have the frame back from powder coat today or tomorrow and I can mock up the motor again now that everything is complete and I will have pan, transmission and TC mounted up as well.

Thanks for the help!

Here are a few links. It doesn't specify 5.7. Andrew, why will the LS6 work and not others?

Those are not it. I am talking about 2010-2016 (or whatever years was for C6) Corvette manifolds.
