1998 tahoe LS swap

[2drhoeon4s]

Ok I have been toying with this idea for a long time now. I have decided. I am swapping out my vortec for and LS1 or LS6. I am selling my old stuff so if anyone wants any goodies hit me up... I have been generating a list of parts, but I am having trouble getting a clear cut list of what is needed.

I have,
Crank Spacer
Motor mounts
SS fuel lines
Water temp sender
Upper rad hose
3 wire coolant sensor
1 wire oil pressure sending unit



Questions..
Do I use any of my vortec motor harness or do I use all LS harness?

Will my factory fuel pump supply enough fuel for an LS. bolt on mods and maybe a small cam?

will my auto trans bolt up or do i need a newer trans from an ls vehicle?

I want to ditch the 4wd and go 2wd. can i replace the output shaft on my tranny or do i need a 2wd trans?

if i swap output shafts do i need a new driveshaft?

i plan to do away with evap and egr. I want to keep Power steering and AC. Can I use all of my Vortec AC stuff with an LS compressor?

Do I need to do a top mount compressor as I know the LS motors have it on bottom.

any help or links to good articles would be great!!!

Also you can easily use your vortech wire harness by adding a few wires and reppining it for a 0411 ecm, here http://www.ls1truck.com/forums/showthread.php?t=46472&p=517395#post517395 Lextech is very helpfull and has all the info if asked.

Vortec Fuel pump will be fine (unless your going turbo or supercharged)

Lextech (LS1truck forum member)(and some others) have a kit to mount your A/C comp. in the stock locale (high mount drivers side)

A bit far...

it would be just easier to the use the wiring harness and the ECM from the engine you will be using. To bad your in bama, I have an extra 2wd 4L60E and driveline for a suburban, you would just to cut it down. The drive line is huge in diameter compared to the stock unit, it's also aluminum. You can change your output shaft and tail shaft housing to a 2wd and re-use your trans if you want. Our you can find a 00-up 2wd and rebuild it to have ready for the swap.

Yea you need a 0411 ecu...If your serious contact Lextech over at LS1truck forum...Read the swap info over and then decide which method will work best for your conversion. If you get a Gen III engine the 0411 ecu is easiest swap ,If you get a Gen IV (58 tooth reluctor) you will need the matching ecu and harness.

thanks for all the info guys!! I plan on reusing my trans since it was rebuild 1k miles ago. I am planning on removing the output shaft and using a 2wd unit, but will i need a custom driveshaft or will the stock 4wd unit work? Or will i need a 2wd driveshaft?

Engine I am searching for is a 98-00 camaro, transam, corvette LS1. I definitely want a 5.7L
