Especially after I do an LT5 cam and ported injection conversion. Should be about 550 horsepower.

I have been dying of indecision with this thing. First off, I keep going back to keeping it as a 4wd but I want to keep the 6 speed tranny. The issue is that I have a perfectly good 2wd 6l90e with 25k miles. I do not want to cut the shaft. Also, I would have to buy the expensive Advance adapter for the 4wd and buy dual driveshafts. That all adds up. I would be then left with a barely used 4wd system that cost alot and still does not solve my ride quality concerns.

Now the frustrating part. I have read a bazillion threads on how to convert to 2wd. That part is fairly simple. The difficult part is that my 2wd crossmember is from a 84 c20. for the life of me I cannot figure out exactly what is needed to run factory height springs but retain my 6 lug wheels. It is very important for me to retain my 6 lug rally wheels. I do not want to run 8 lug or 5 lug wheels. When I am ready to upsize the wheels, I want to keep 6 lug. I just do not understand why it is so difficult to have the exact 8 lug rotors made but with 6 lugs.

I am going to try to track down the ece style 3/4 ton to 1/2 ton spindle if it is still made and run 6 lug 1/2 ton rotors. I have the equipment so I might as well use it. I just wish that there was a simple conversion rotor from 8 to 6 lug. Things like this frustrate a simpleton like me. A simple 8 lug rotor blank could be machined to 6 lugs instead of having to change rotors, calipers pads, etc.

I think for the moment I may just run the holley terminator x max with the 6.6 and the factory th350. That way I will have the new motor and still will be 4x4. When i am ready, I can decide on which way to go either 2wd/6 speed or 4x4/6 speed.

I'm pretty sure you can use the rotors and spindles from your 72 on the 84 a-arms as long as you change the 84 balljoints to 72 balljoints. You may also have to change the tierod ends but not sure about that.

Good luck, Rg

My 72 is 4wd so I cannot use them.

I wish I had access to someone with a 2wd to test this theory.
If it was not for the fact that I am currently laid off, I would have gone and purchased a bunch of parts to get this figured out.

Sorry, for some reason I was thinking 2wd. Where are you in Illinois? I have lower a-arms from a 86 that you can have if you want to drive to Murray Ky.

I am in the far west burbs of Chicago. Essentially where things turn into corn fields!

The 86 control arms, They are C10 arms or C20?

Funny thing is that I had a young troop that I did a few TDY's with from my unit. He lives in Murray, Ky with his young wife. Good kid.
