1995 Silverado TB350 to 2003 6.0l 4l80e Conversion

[blownshovel]

I have been researching for a couple years and am moving forward with the project as my transmission went out in the truck.

My current plan...please critique or fill in voids...

TransDapt Engine plates

EXHAUST:
Use 2003 exhaust manifolds.. where can I get some flanges that bolt up?: thx Gator
02 sensors how many and location? in Y pipe or near cat(s): removed rear O2's

TRANSMISSION:
Use 4l80e yoke on my current driveshaft
Hook up vehicle speed sensor

FUEL SYSTEM:
Inline 255 Walbro
2000 Corvette regulated fuel filter: not needed as I have a dual line rail

TBW:
The Engine is equiped with it and I believe I have the control Module but need an 03 newer pedal setup. Still need to work on getting cruise control

COOLING:
Check 95 hose to see if they fit. If not head to the local store to find something that'll work: 99 truck hoses direct fit my 34" radiator
Will need Electric fans to cool the radiator Factory F body or Truck?: Used 99 Caprice

Air Conditioning. Fab 95 bracket or make a bracket to mount 95 compressor on..have heard 92 camaro may work with some changes.

WIRING:
Sort through harness Looking for 2003 HD2500 and 1995 C1500 diagrams....any idea? Alldata?: Various sources and troubleshooting

Gauges:
try to adapt 95 sensors to lsmotor
Tach ?
Temp...in head hole... retrofitted TB factory sender
Oil Pressure? Where is a good location to tap in? : Replaced LS sender with TB factory sender
Odometer/speedometer?

ENGINE MANAGEMENT:
Will need to mod factory ... at minimum tire size/rear gear but looking into HpTuners and EFILive

Lots of views but no responses? Hopefully that means I'm on the right path. I'll try to keep updating this as I move forward as others may run into similar problems or questions....

I pulled the TB motor out and dropped the LSdrivetrain in.

I have ordered many parts....

I am using 99 truck radiator hoses


I'll try to update when parts work/don't

I bought the Corvette style filter and some adapter fittings but do not need them. I have a dual line engine

It looks like I will need to drill new holes in the frame for the trans crossmember. The mount on the 4l80e is 5-7 inches further back than the 4l60e.

Wow, that's my truck's twin(if mine had shiney paint and a narrow box).

I guess the dual line setup from a truck has a regulator built into the fuel rail. I wonder if it can handle full fuel pressure.


As for the tach, if you have in-dash tach already you can contact bakerelectronix.com for a tach module.

Yes your twin...when I first came on here few years back I thought dam* I need to do that covnersion as well.....

The dual line had a regulator on the rail? Can it hold pressure? Good question Thoughts? What about aftermarket FPR options?

I hear of these dual line setups all the time have never seen one. I guess the trucks I&#39;ve worked on have been the newer models, all single line feed. The truck radiator hoses work great, just be sure you use the ones made for your size radiator. Do you have a 28" or 34" radiator? I have the 34" so I bought the hoses to fit a one ton model truck since they usually have the 34" rad.

I&#39;ve seen vehicles with single and dual fuel lines but don&#39;t know the rhyme or reason. A year to year thing maybe?

I didn&#39;t even measure my radiator but picked up some 99 C1500 hoses that will work.

I did run into a problem today. I was gonna put the 4l80e yoke on my stock 4l60e shaft... I bought a spicer conversion joint and the diameter is correct but the yoke side is not wide enough
Anyone have a part number? I ran a 350 shaft in my 70 chevelle and bought a cross shaped shaft in the past...hmm might even be what I need now.. but I don&#39;t have a part number

what I need:

Yoke Side uses 1.188 cup diameter and 4.124 width
Driveshaft side uses 1.0640 cup diameter and 3.6350 width
The stock install utilized exterior spring clips to hold the joint in place

I went with the 99 hoses. My truck has the 34" radiator and they fit nicely

Also I made progress with other lines this weekend.
Trans cooler lines attached
PS lines attached re-using the 95 hoses
drilled/tapped/attached throttle body warmer line

I picked up another Yoke and will check it out to see if it&#39;ll fit the need.
