Here is an up to date pic of the truck with the inner fenders and radiator support installed. I went with the Griffin LS Swap radiator from Summitt.... I believe the same as CaptSmith.

Image

I also used the LPP shorty headers like the Captain. If anyone else is wondering... LPP does ship their headers with new bolts and gaskets. I couldn't get an answer from them via email before ordering.

Image

Unfortunately, I am not going to have enough room to use the stock clutch fan, so feel free to shoot me advice on choosing an electric fan.

Image

Anyone have any idea why there is what looks to be an overflow nipple below the inlet on this radiator? What do I do with that thing?

Does anyone know what this connector is? It's about 10 inches from the tranny plug on my 5.3 harness. I thought it was going to be my speed sensor, but there's no way it's reaching the back of the T-case. Perhaps they just use the same harnesses for the 2wd trucks and this is the speed sensor that would have plugged into the tranny on a 2wd truck?

I know everyone is interested in clocking rings especially with the NP241 swaps... Well here's a pic of how my NP261 sits in the truck.

Image

Although it doesn't look like it in this pic, the drive shaft clears the tranny cross member by about 3/4 of an inch.

Image

Here's another pic of the drive shaft. I was able to find a used GM drive shaft in very good position for only $50. Then the drive shaft shop charged me $230 to shorten the tube, put a 1310 yoke on the end, and install new u joints! Might go with a custom shaft for the back if the alterations are going to cost that much. Has anyone used Denny's drive shafts?

Electric Fan: I am using the fan from a Lincoln Mark VIII. At 4,500 cfm or so, it's about the best you can get. The factory Mark VIII fan shroud fit the Camaro core very well.

Image

I cut the Mark VIII fan shroud thinner to make as much room as I could (I moved my engine 1" closer than the closest factory engine mount holes). You should have plenty of room for a Mark VIII fan.

We used Deny's Driveshafts for my father's '59 Impala. Not cheap at all, but very nice stuff!

Here we are with the 5.3 harness reinstalled and the Jeep engine harness in process of being thinned.

Image

Here are a bunch of questions...

I am assuming the three red wires that hit the bulkhead connector at pins D4, E4 and G4 all get battery power. Can I cut off the fusable links before tying them into the battery?

Can I use the yellow wire from pin B4 (alternator and ignition feed) to feed the "keyed on" source for my 5.3 wiring?

Can I use the green wire from pin A6 (starter relay feed) to feed the starter solenoid on the 5.3?

And is this module underneath the passenger side dashboard (below) just for the stock cruise control? Can I remove it since I will obviously not be using the stock cruise control with the 5.3?

Hmmm... you probably have your rad a good 3-4" farther forward than me. I like the fit of the fan that you have there and the amount of air that it moves but I am not sure if I will have the clearance with how my rad is currently mounted. I should have measured the distance between my rad and the clutch fan spindle.

That is for the VSS. For some reason, GM used a male to male adapter. I believe that the VSS should have a cable coming out of it that connects to that connector.

Yes, csuengr is right, that is your VSS sensor. The adapter (clocking) ring I used from Novak had a sensor and wiring harness for the VSS. I'm not sure how you will do this.
I have the same question about the box under the dash on the passenger side. Mine is black but I'm not sure what it is for. I was also thinking of getting rid of mine. I have found stand alone cruise control systems that hook into your VSS sensor.

True, but my engine also sits further forward than yours. I just went out and measured, and at its deepest, the fan sits 5-1/2" off the face of the radiator core.

The yellow box in just the cruise control. It can be deleted. If you carefully pulled the whole cruise system (didn't cut any wires) you can sell it on Ebay.

I figured that I should post self discovered answers to the questions that I have posed in this thread. Perhaps my ramblings will benefit someone with the same questions.

In a thread about a year old, someone suggested a neat way to handle the torque converter signal that is needed for the PCM. Rather than worrying about wiring a relay, the brake switch from a mid 80's chevy truck with cruise control can send the proper signal. I am going to order one from Autozone and give that a shot.

The fusible links can be replaced with regular fuses or breakers. In past threads, Serehill has suggested these http://www.delcity.net/store/Auto-Reset ... t/p_198669 rather than fuses or new fusible links. Would 30 or 40 Amps suffice? Do I need one of these for the battery to starter wire too?

I can't find the male to male adapter for the VSS that csuengr mentioned anywhere. Instead, I ordered a new VSS connector and will splice into the green and purple wires. Should give me enough leash to reach the transfer case VSS.

I sent my PCM to Brendan today for programming. My tire size decision had been the delay and I finally picked 31's. The ones that are on the truck now are 29.5 in and I don't think they look lost in the wheel wells.

The thingy at the end of the cable in your hand is the male to male adapter.

Unless the adapter is glued on, this is a one piece connector... there isn't a clip on the other side. What's odd is that the VSS sensor on the T-case looks like it requires the same weatherpack connector that this thing requires. So I have been looking for wires with weatherpacks on both ends... this is what I thought you meant by "adapter". Couldn't find it. While I am still scratching my head about how this was hooked up in the Silverado, the easy thing to do is just going to be to cut this dumb thing off and replace it with a normal VSS connector.

You're missing the transfer case part of that harness. It has the same connector on each end for that vss circuitry.

Get the rest of the harness.

I wouldn't cut that connector off. I don't know what exactly it does, but GM didn't put it in there because they thought it looked neat. It probably has some kind of resistor or filter or something in it.

Its called a VVS adapter and it's only used on the automatics. It's there for a reason.

Used on 4wd auto only. I'd imagine it has something to do with the 4wd low and a correction factor for the auto tranny. Just a guess.........

False, it was used for the two wheel drive and four wheel drive versions. The two wheel drive it was plugged into the transmission, the four wheel drive versions it was plugged into the transfer case.

Talking about the "adapter" as shown below his thumb in this pic. I don't have one on my LS (2wd). It must be some type of adapter for the TC VSS.
Looking at the diagram, only shows it for the 4wd. http://ww2.justanswer.com/uploads/thero ... el_vss.gif

From what I can find, the transfer case wiring is part of the chassis harness. I had been hoping to buy a wire that went from point 3 below (the VSS sensor) to point 1 (the adapter connector)
