Well, I have been working on the my Unlimited 91 Suburban build up!!! So far I have Dana 60 with 5.13's, Yukon 35 spine inner and outer axles new kingpens, OX U-Joints, ARB and ORD cross over steering, spindle seal kit wheel bearings and single wheel bearing hub's and rotors, all new parts and the same for the 14FF ARB and 5.13 with TSM rear calipers with parking brake's S/S brake lines.
BDS 8" springs and a 3" body lift with poly bushings. ORD steering brace and greasable suspension bushins all the way around 1" zero rate add a leaves. Heavy duty front shackles and a lot of other parts..
NOW, the motor Is a GM marine HP3 with over 600hp and 600ft-lbs of torque, GM has been working with me hand and hand on this motor. PCM (computer) with harness, custom programming, TAC module and electronic pedal are from Speartech out of Anderson, Indiana.
Ok, I am still try to make up my mind on the Trans. I am running an ORD gen2 doubler. Would like to run an Allison but do not have any experience with one. Is the output shaft 32 spline and the proper diameter? If so can you just re-drill the face of the NP-203 and bolt the case directly to the tranny and plug the existing holes to prevent oil leaks. Or do you need an adapter to mount the np203.
Thank you for you time, Matt!!!

You forgot to mention what size meats your runnin'.

Also, why is there a handicapped plate on there? Anyone who can get in and out of that thing certainly isn't in need of a plate.

Great looking sub :waytogo:
 
I cannot help you either with the Allison question, but do you You have more pictures of this build up available? I have a 1985 1-ton single cab dually, and I was think of getting a 3/4-ton Suburban and transfering all the running gear from my 85 Dually to a Suburban (daul wheels and all). Then I would have a 1-ton dually suburban. I think that would look bad ass.
 
Why is there a handicapped plate on there? I must be handicapped:haha: :haha: And yes they are 40/13.5/17 MTR's

very very cool. what mirriors are those, any issues with the body lift. Again very nice truck :bow:
 
not all handicapped plates mean wheelchairs


and ORD made a doubler for the Allison in the extreme 4x4 suburban gorilla show
 
Lets get this thread back on track guys. No need to beat the issue about the handicapped plate.
 
GM Marine Engine HP3

GM has combined the previous standard GEN VI short block, with the latest LS1 Cylinder Head and Fuel Injection Technology. HP3 engines have High Flow RECTANGLE (LS1 Cathedral shaped) SPREAD PORT 14 Degree Heads and a New Raised D-Shaped Exhaust ports, with 2.19 int. 1.72 exh. valves. These heads flow 340 on the int. and 250 exhaust. The block is a standard Gen. VI 4.25 bore, 4 bolt mains, Tall deck (10.2) Heavy Duty casting truck block. To increase strength they added (4) EXTRA Cylinder head bolts, making (5) per cylinder. These heads can only be used on these blocks. The fuel injection system is Identicle to the LS1. It has the same (SFI) Sequential Fuel Injection, with a low profile Aluminum intake manifold. It looks exactly like a giant LS1 intake. This engine has the same super efficent COIL ON PLUG IGNITION SYSTEM (distributorless), and a Large 75MM Throttle Body (LS1). This engine has a special Hydraulic Roller Cam (242 252 @ .050 114LS) with a smoother revised firing order 1-8-7-2-6-5-4-3. Like the LS1, this engine has Hyperutectic pistons( 9.5 to 1 ), Forged cracked cap rods (6.535), nodular Iron internally balanced (4.37) stroke Crankshaft, aluminum oil pan w/ windage tray, aluminum timing cover
