I purchased a GM Connect and Cruise LS3/4L70 package. It seems they come with a water pump, damper, and oil pan which are unable to be used with any accessory drive packages I can find. This is going in a 1972 two wheel drive Blazer and will have AC (factory AC Blazer). the water pump and damper have the following part numbers
Water pump 12604630
Damper 595169
I looked at the Corvette, CTS V, F Body accessory drives and they all use different damper and water pump so on to of the $1,000-$1200 for the drive kit I would need about another $300 for a water pump and $100-150 for a damper. None of these use the water pump or damper that the C & C package comes with (thanks GM)
So even using all GM parts I am looking at $1500-2000 for a GM accessory drive. I prefer to stick with all GM for a couple of reasons. 1 part availability and I like that the AC compressor has its own belt (I probably wont have the AC finished for a couple of years and prefer not to spin the pulley when it is not needed). Holley uses its own water pump as do a couple of others. The more I research the less I know what I want?
Any suggestions on accessory drives? I am open to any manufacturer and prefer made in USA if possible.
There are only three offsets. Corvette, F-body, Truck, if you call the corvette 0 then the F-body is 3/4" out and the truck is 1.5 inches out. I'm not sure what offset you have but as long as you have the room you should be able to use the parts that came with your crate engine, Holley and others make spacers that you can be used to correct offset. I have a truck off set crank pulley, with a Camaro water pump (Camaro had auto trans and VVT) and corvette ALT/PS bracket with a 1.5 inch spacer, Denso fixed displacement ac compressor with the factory truck bracket. I'm sure with a little research on this site you can find a setup that will work well
Oil Pan is a different story, you need to purchase one that fits your body style. 2009 LY6 Motor, 2010 Camaro water pump, Corvette Alt/PS bracket spaced off the the head 1.5 inches Homemade 1.5 inches thick spacer used to line up corvette alt/ps bracket with the truck off set.
Pic taken during my install. An Alan Groves low mount A/C bracket -- separate belt for A/C; ICT Billet Alternator low mount; CTSV power steering bracket and pump. All with Corvette pulley spacing. Way, way, way less than the 4 figure numbers you're quoting....
Look for interference of the AC compressor to the frame / mount. As long as you didn't use cheap adapter plates, you should have good room for the low compressor on that frame.
Look for low driver side accessory clearance to frame / steering.
Everything else should fit in that truck. There's nothing wrong with going 100% production truck parts and relocating the passenger side high pulley or tensioner so the LS3 intake TB clears. However, if you can use the 0 offset water pump and damper you have with the CTS-V or Vette compressor, and the setup Michael presents, there's nothing wrong with that. 38mm offset either way isn't an issue in a full size truck.
Go with what you like. I like low, out of the way, so the OEM compressor placement is great. In some engine bays, it presents frame contact. There can be issues on some platforms on the drive side with the low alt. or pump, but you may have no issue at all. Check it out.
Would you happen to have part numbers and or links?

I also like the low AC and tucked accessories and prefer factory GM if possible. I really need to get this figured out.

It was easier for me to simply google what I described above and come up with the part numbers than to dig through my records and find them. That's what I did below. STRONGLY encourage you to do your own research to be sure these will work with what you're trying to accomplish. Also - I fabricated my own motor mounts - there's no interference with the a/c compressor - but it's close. You'll find references to not being able to use the low mount compressor with Corvette spacing IN A CORVETTE because of possible motor mount interference. Again -- do your research. Just about every one of these swaps are unique in some way or another.
I experimented with belt length until I found the right one -- puts the tensioner in the "marked" range of travel (not too tight, not too loose)
I use a Sanden rotary compressor, an Escalade 145A alternator and a 'small' (I think they call it gen 2) power steering pump with a remote mount reservoir. Looks like this all finished....which is to say, you can really only see the PS stuff with the hood up. Compressor/Alt are buried.
You can buy an accessory drive kit from pace performance for around 7-800 dollars. All factory brackets with bolts. Then just add the AC bracket of choice.
All the new LS3 C&C combos are 2010-2015 Camaro now. You can keep the Camaro waterpump and balancer and use the GM Corvette brackets by using the Holley 21-3 spacers behind them. but for the A/C compressor, I think you would have to use a Camaro-2015 compressor bracket. The spacers will make the front belt line up with the Corvette accessories, and the 2010 - 2015 Camaro A/C bracket should keep the compressor lined up with the back belt.
You are correct! I just checked the one I bought last week, and it had Camaro exhaust and oil pan, but Corvette spacing harmonic balancer and water pump. I just looked at it in the crate and saw the exhaust manifolds and pan and figured it was all Camaro. Saved me having to change the pump and balancer! I am putting it in a Gen II Nova, and I know it will be tight.
Probably mine had the Camaro pan too John -- but I don't know enough about them to recognize which pan is which. I was replacing it anyway -- so I let the ebay buyers be responsible for ID'ing the pan from pics and being certain it was what they wanted.
