5.3 swap i bought a 2004 5.3 and 4le60 trans yesterday, has the whole harness, no ecu, or pedal or mass air, I've already ordered the pedal, been looking into getting a ecu, and mass air sensor and air box. I'm looking for advice....looking for companies to send my harness and ecu (once i get it) to get chopped up and tuned, and any other advice as to stuff i might need, and was wondering if i can use my transfer case...i have a np208 or if i could buy a adapter and use a stock one from a 2004 chevy? this is my first swap and trying to make it as painless as possible
i should mention that this is going into a 84 k10

You can use the 208 case with the correct transmission adapter that can be found on ebay as long as the case uses 6 bolts to bolt to the adapter. You might even find one that's a 5 bolt if that's what the case has. You will also need a VSS. Dakota Digital has one that is 8 pulse and is pass through. Meaning it also has the speedometer cable connection. A 241 transfer case is a better case but they are harder to find with the passenger side drop. I hit the jackpot and found one on ebay for $75. I am gathering parts to put a 5.3/60E in an 85 K5 blazer so I have been researching all of this.

The ECM needs to know the vehicle is moving or it will do strange things (like stall) randomly on deceleration.
A friend just did a K5 Blazer with an 2007 5.3 swap and it looks factory under the hood. The customer he did it for wanted to keep the original transmission so he needed to make a kick down for the drive by wire.
It was the first drive by wire vehicle I've been in that wasn't an electronic transmission or wasn't a manual transmission. Really strange, but the customer was happy.

dman,, you're also going to need a TAC module to go with the pedal. Did you get that with the motor? You HAVE to have the VSS or the transmission won't know when to shift. There are other problems associated with not running one, but that will be your main problem.

Back to your harness, there are a few sponsors here that can mod
your harnees most also sell Ecm's and MAF's and also flash EMC's. PSI, BP and Spantect
are a few all with many happy costomers. I'm sure there are a few
more sponsors here that can do it also. I'll be ordering a harness,
EMC and MAF in a week or two. After reading posts here about the nightmares
of people using guys they found on CL or somewere, for peace of
mind I'm going with one of the sponsors here that has great feedback
from there costomers.( just my .02 )

The fuel issue is easy. Get a gas tank for an 87 Truck as they were injected. Also get the gauge sending unit for injection and then pick out a good intank fuel pump from Summit. I have all the part numbers if you need them. That's the setup I have sitting in my garage right now, waiting on me to start the swap. You can use the vette filter/regulator setup if your fuel rail is a one line type.
