4.8 Identification Help - Pics Added
Looking for some help identifying the 4.8 I have. I am told it came from a 2012 U-Haul van/truck. I do not have any harness, PCM or DBW pedal. I have found a couple of numbers engraved on the heads and the block/head casting numbers but I can't find anything that resembles a vin number from the donor vehicle. Is there any vin or derivative of a vin on the motor? If so, where would I find it?
Thanks,
Lane

Untitled by Lane Bauer, on Flickr Next question.... I do not have any harness or DBW pedal, any sources other than wrecking yard or car-parts? Will a basic silverado/sierra harness from same year span work?
EDIT.... I am finding several option available for 03-06 Silverado/Sierrra, is it safe to assume these will work?

The Vans did not have flex fuel.
They could have very well put an LM7 into it, and you use the exact same spacer and flat flexplate mating a 5.3 to a 4L80e.
You'll have to pull the pan and look for crank or rod casting numbers To determine either 4.8 or 5.3.

The 3/4 tons are usually 4.8's or 6.0's
An L20 would have active fuel management which would make it a gen4 block.
AWD in a 4 speed would be likely be a 60E style transmission as well.
I bet that came from an 07 or older vehicle... The date code is cast on the Pass side of the block near the water pump. would also be cast into the heads under the valve cover area where the rockers are.
Although I have seen a 2001 that was a LU3 4.3L V6 in a 2500 chassis... Lucky for me they left the 4L80e alone as a result...

Untitled by Lane Bauer, on FlickrI talked with Josh at Team 208 Motorsports today and he told me that the 8 pin plug for the DBW on the throttle body says it's a 2003-2006 era motor. Do ya'll agree with this?
The vans how ever used a cable style TB up until around 08-09. they switched to electric but i have not worked on one and am unsure what they switched too
FYI The plastic rails in the back round are non flex fuel style rails.
