91 crew cab project

I got mine september of 2007 its crazy that they've gone up over 100 bucks
 
Only diff betweet dually and non dually is the front hubs/rotors and the rear axle. If you can find a dually, get it, sell/trade the dually hubs for single, find a 1 ton rear so it will bolt in. Or get a 3/4 and move the perches. Hopefully gonna be getting a crew cab myself...Will I be part of the Crew Cab Club??lol.

ya, the burb has the same wheelbase of a standard cab long bed truck, and the crew cab is a lot more. burbs up to '87 were 129.5" and '88-'91 were 131.5"

Umm, almost, but no. Burbs are the same for '73-91; the pickups did change for '88. See below.

I have been looking for a 91 crew cab without any luck. So I am planning on building one. Dooes anyone know if a 91 Suburban frame is the same as a crew cab?

As mentioned, sixpacks are a totally different animal than a Burb. Also note that sixpacks all have the one-tone frames, i.e. taller and thicker section, and the narrower spring spacing in back.

Also, take a good look at Burbs, and see how close the back tire is to the rear door. The rear axle on a Burb is WAY forward when compared to the pickups, so it has a longer rear overhang than it would if the axle was centered. (Presumably this was done so soccer moms could turn their Burbs more easily :haha: )

Lessee, some numbers:

73-91 Blazer 106.5" WB, 184.5" LOA
73-91 Suburban 129.5" WB, 218.5" LOA
73-91 pickup crewcab 164.5" WB, 244.5" LOA
73-87 pickup shortbed 117.5" WB, ~191.5" LOA
73-87 pickup longbed 131.5" WB, ~212" LOA

Overall lengths for the regular cab pickups are a bit vague due to bumper options. Remember that the crewcabs, Blazer and Burbs kept the old body style for 88-91.

Now, there ARE some odd length crewcabs, which were sold as cab and chassis trucks, i.e. no bed. There are a few different sizes AND some were modified after GM made them, so the only way you'll know what specific wheelbase any such truck has ... is to break out the tape measure ;)

Oh yeah, and a crewcab is fricken huge, and has the turning radius of the Exxon Valdez. Ask me how I know :D

I guess the best way to get my CC is to start looking for a CC dually and get new front hubs and a new rear axle to make my no-dually CC.

yep, especially since your gonna make it a shortbed
 
Dually are alot easier to find thats for sure. But a srw shouldnt be to difficult to find. Of course I ddi go out to Colorado to get mine:D
 
60 up front and a 14ff rear. Duallys run a 70 rear inless it's a cab/chassis then it will be a narrow 14ff.
 
I feal really stupid now. I have been searching for "Crew Cab and not crewcab" I'm in the springs, I see there is one right here in town. I guess 89-91. I want the 91 grill.

swapping out the grills isnt difficult. 91 would have a 4l80e though(could be wrond about that
 
well just pick up an Crewcab from 81-91 and swap to the 91 core support and grille ,easy swap.

I thought maybe you wanted a 91 because of the 4L80E
 
Is the 4l80e really that much better than the 400? Have not read that much about that tranny
