Ok guys, I have a question....? I am getting ready to do a 6.0 swap into a 96 GMC 1500 truck. I am in the process of gathering parts.I have the opportunity to purchase a wrecked(rollover) 05' Tahoe running and driving and a 07' LQ9 that was taken out of a truck because it flattened a cam lobe. the LQ9 is complete minus accessories, no computer or wiring. My thinking was buy the Tahoe for the wiring harness, computer, gas pedal assy. and any of the small stuff i might need and then sell the 5.3,transmission,front and rear differentials, and ant thing else i might be able to sell. that would basically get most of the small stuff i might need for basically free. I'm going to pull the LQ9 apart put new rings,bearings,gaskets,ported ls6 ported oil pump, mill the 317 heads .020,( install a ZO6 LS7 cam, lifters, valve springs, have a good valve job done and set up the spring height,ect. head studs, arp rod bolts. OK, Now the problem(as many of you will know already) the computer and drive by wire pedal is all coming from the 05' Tahoe(5.3) that is a 24 tooth reluctor wheel wont work with the 07' LQ9 that has the 58 tooth reluctor wheel. My Question is....Because I'm going to probably have to havethecrank turned and buy new bearings anyway,, can i either change the reluctor wheel to a 24 tooth or buy a crank kit for a earlier 6.0 that is 24 tooth and of course the crank sensor??? Can SOMEONE shed some light on which would be the best way to go. This is somewhat of a budget build for my 17 year old son. This is my first LS swap so I'm new to the LS world. Thanks in advance for any help.

If the crank is coming out anyway, a machine shop should be able to change the reluctor wheel. It is apparently fairly easy to screw up so finding a shop that knows what you are asking for would be key IMO. I was almost down this same path and lucked upon a 2005 LS2 which is kind of a mashup between years and has the 24x wheel. Supposedly.

Thanks for the input. I found out today that the reluctor wheel change itself won't be that big of deal. The other problem I could have is the Z06 LS7 cam I have might be an issue due to one or the other having 1 bolt vs 3 bolt. Might require a new cam gear and relocating the knock sensor to the side of the block. Any input/info would be appreciated.

On the knock sensors, if you are running LS1 harness with LS2 or later block, drill and tap the existing sensor holes to M10x1.5. Just did it last night and turned out well. Home Depot sells a Dewalt bit and tap set of that exact size for about $9.

You can see a pic here where I was asking for confirmation(and got it):

Did the '05 have the LS1-style(valley cover location) knock sensors?

From what I know the factory LS7 cam isn't really a desirable piece. I accidentally bought one thinking LS6 and it sits and laughs at me. It's got some weird specs to get over some odd factory exhaust imbalance. Would probably still run OK but there are better cheap cams out there. If you want another one cheap let me know..it's immaculate!

I will either be having a harness built for my application or having the harness i'm getting from the Tahoe modified to work with my application. I have been looking at other camshafts. Any suggestions? here's what i have figured out so far. Stock bottom end, LS6 ported oil pump, stock 317 heads(for now) milled .020, headers, 2 1/2" true dual exhaust, stock truck intake and injectors (for now) and a tune and . I picked up a posi unit and a set of 4:10 gears, and i plan on running a 3000-3200 stall converter. I have been looking at cams but there are so many choices. I'm thinking about having a cam spec'd for my application (taking into consideration the other mods i plan on in the future). The other hurdle i have to cross is converting from drive by wire to drive by cable. Thanks for the input.

if it is an lq9 it should have the 24 tooth reluctor anyways. you can pull the crank sensor out and look to see which one it has.

Well OP says it is a 2007 motor and 58x so I assumed. I am confused now. I figured, like OP, that if 2007 it would be 58x. Did LQ9/gen III carry over later than I thought?

Here's pics of the different reluctor wheels. I would physically verify. If it is 24x you are ahead of the game!

I'm fairly certain that some 2007s (Silverado "classic") have the genIII motors still. You should also be able to tell by which computer they have.

Sounds like it is worth checking out the reluctor wheel. Aren't the two sensors different as well, like one grey and one black?

I believe so. also knock sensors in lifter valley vs sides of block, cam sensor top rear vs front timing cover, etc.

If it is a lq9 it should have a 24x reluctor wheel. 2007 was the last year of the Lq9 in the classic Sierras and Silverados.

So this should bolt in and run with a bit of tuning right?

Thanks guys. I know there are grey and black crank sensors. Can't remember which on is which but that's easy to figure out or maybe someone could clarify. It would be awesome if it has the 24 tooth reluctor. I will be picking up the engine this weekend. I know for sure it came out of a 07' 1500hd vortec max. If it is a 24 tooth that will make it much easier. I have to tear it down anyway because it ate a cam lobe, so I will know for sure. Next thing is figuring out what I'm going to do about the wiring harness. I have one from the 04' Tahoe I could modify of maybe just buy one. Any suggestions on a good source for a decent price? I've been quoted anywhere from 926.00 (Street & Performance)for a new on built to suit my application, 310.00 to reflash my computer and remove the VATSto 475.00 (a guy in Houston, can't remember his name) to take my(Tahoe)harness a modify it to suit my application and that includes reflash of computer. I was told the 07' 6.0 is the 58x just to clarify, don't know yet what it is for sure. Will know this weekend. Thanks again for the help..

A new 24x reluctor wheel from Jegs is $20.99. That's a GMPP part. It's the other mods it will take to change from 58x to 24x that I'm unsure of. I'm just going to wait until this weekend and I will know what I'm facing.

Thanks. I'll know for sure this weekend what I have after I pick it up.
