91 RCLB Build -Swap and bag-

[LsSonoma]

Well started over on GMT400 and dont seem much help so thought I would throw my build up over here too.

Got a 91 RCLB from my dad. 258k 5.7 auto, all original. So far I have bought almost full bag parts and motor and trans. Don't plan to start build until have all parts.

On the bagging side I have never bagged a ride so go some questions on that but have a pretty good idea. Worked on several and been around em a lot. don't know what shocks to run and haven't decided on what tanks going to run.

List of what I got so far
Michigan Metal Works plate control arms
H.D. universal 4link. 1.5 d.o.m with .25 wall
Slam SS-7 for front and SS-8 for rear
SMC 1/2 Valves x8
AVS switch box
1/2 line
upper cups for front and upper and lower rear brackets
165/200 press switch
York 210
Step notch


Now to the funner side for this site. Picked up a l96 6.0 VVT motor from 2010 2500hd. Bought complete pan to engine cover, m.a.f., start, manifold, o2s, harness and pcm. Also picked up a 6l90e.
the swap don't seem that bad to me we have done 4 ls swaps just no Gen 4 yet. Should pose all new wring issues, lol

Just got a few question to start with.
How far does a truck oil pan hang down or what pan are people using?
has anybody done a 6l90e, does it hang below frame rails?
Pretty sure factor manifolds work. correct if wrong








Oh ya and throw up my DD. 98 Sonoma 5.5/7 drop on 18x9.5 c5 wagon wheels, 5.3 finishline level 4 4l60e, 3200 stall (fullsize beast in background)

Sounds like a cool project but know nine of the questions you are asking! Never been a Sonoma fan but man that truck looks good and bet it runs good too!!

Thanks s series kinda my thing up to this point, this is the third 5.3 one ive had. It runs ok just a stock motor, just enough to ruin some tires.

What oil pans dont hang down below the cross member. i plan to lay this thing out and no body talks about it. so guessing a truck pan is ok, i have a H3 oil pan that i plan to run that is left over from a s10 build where it was to low.

Fbody pan.

[LsSonoma]

is this the only pan that dont hang down?

The f body pan would be the best for clearance. It's hefty on the wallet tho.
I have the same body style and mines bodydropped. I'm going to run a ctsv pan on mine.
It's a bit deeper than the fbody pan but according to my measurements should still be bearly above the crossmember.
If you plan to lay frame (by your mmw purchase I'm assuming you do) then the truck pan is going to be a problem.
Post up your progress! I need to update mine.
Not too many bagged and swapped rides on here so the few of us need to stick together!
Nice dime BTW, I miss my first gen blazer. 350, 40 over...
It was a lot of fun.

Well the progress is the parts pile building right now. And your right there are not many swapped bagged rides. Makes it hard to find info. seems like the build threads i read nobody talks of oil pan because most are 4wd or not low. You are right it willl lay flat, that was the point behind the arms. factory the corners of arms hit ground and hold the frame off ground at front about 3/4. MMW claims these make it lay flat(they better be right). The Fbody pan isnt that bad it is $200. I have one in my sonoma becuase of ground clearnace also. My buddy was joking the other day how it funny all my builds we have sever ground clearance issues.
