settle an argument, this will require proof Im about to swap in a 2006 LS2 into my 99 TA.
Whats the deal with the reluctor rings? What ring do I have in my LS1 now? What ring is in the LS2 Im wanting to buy? I appreciate someones word but for whatever reason, Im now being told I have a 58 tooth when I was under the impression I had a 24 tooth... WTF do I have..??? Please provide a link so I can be more sure of my decision...
2006 LS2 reluctor ring is.....?
1999 LS1 reluctor ring is.....?
If you have a link, that would be outstanding...

You have a 24 tooth wheel, all f-bodies did. Our computers are not compatible with the 58 tooth setup, meaning they CANNOT run them. If you go to a 58 tooth wheel you must get the Lingenfelter conversion box to dummy down the signal for our computers to function correctly. Be careful going to the newer stuff, it gets confusing when starting to talk about 1 and 3 bolt cams and 1,2,4x cam sprockets. More headache then its worth in some respects. I finished not long ago a 2007 Gen 4 5.3 into a 94Z. All the little details to get it to run were silly.

The LPE 58x to 24x conversion box needs to see both a 58x crank gear and the 4x cam gear so the 2005-2006 GTO LS2 timing gear won't work. A 2005-2006 GTO LS2 (and a 2005 Corvette LS2) has a 24x crank gear and a 1x camshaft gear (see gear "C" in image below). That timing gear produces the same signal as the rear block mounted sensor found on the Gen III engines (and the rear mounted camshaft speed sensor won't work either).
Attached are images of the different camshaft timing gears (for a 58x engine with an aftermarket 3 bolt camshaft you want gear "B").
I also included pictures of the crankshaft reluctor wheel. If you are not 100% sure what reluctor wheel is on the engine you can sometimes take the crank sensor out and look in the hole to see the tooth pattern on the wheel (or drop the pan).
I also included a picture of the timing cover that has the sensor in it for reference. All the timing cover mounted camshaft sensors are the same so any of them will work.
BTW - for the 58x crankshaft signal to work properly you also have to have the crankshaft sensor used on the 58x engines (different sensor compared to the 24x engines).
Our instructions explain this in more detail (LINK).

And I'm pretty sure when we were sourcing the sensors we would ask for 2006 Corvette parts to make sure we got Gen 4 stuff. So it sounds like the potential engine has the 58/4 combo with the single bolt cam setup. Lingenfelter has some great information on there site and posts they have made here.

I see Gen 4 top cover (notice the oil pedestals for DOD which will require a delete cover with o rings to function in your car) a 58 tooth Crank sprocket and a 3 bolt 4x cam sprocket. So on top of the DOD delete valley cover, you will need a Lingenfelter conversion box to dummy the 58/4 signals down, AND a front mount cam sensor relocation cover because there is no provision for the rear mount cam pickup. Prices are around: $100 valley cover, $250 for the Lingenfelter box, and $150 for the front cover PLUS both cam and crank sensors since yours will not work.

Thank you... I think Ill look elsewhere.. do you have any specific 6.0 motors that will be as close to direct swap as possible? I really want to go with an LQ9 and big cam or LQ4 and some spray... Ive gotten so many replies I cant make heads or tales of them...

You need to do the research and see when they (each LS based vehicle) changed from Gen 3 to Gen 4. They changed different years. The 5.3 we did was out of a 2007 Silverado. However, during 2007 both Gen 3 AND gen 4 engines were available in Silverados. It was kind of a transitional year. You'll need to know this if searching for an engine by what it came out of. You want a full Gen 3 setup and it will drop right in with no additional BS needed.
