i want to make my 84 k10 into a pavement pounder i have seen a lot of guys draggin diesel trucks as of late and i want my truck to put up some good quarter mile times. iam currently looking to replace the entire drive train in the truck so hit me with as many combos as possible. the truck will only be used on weekends and cruise nights .  

Well a "hot" ticket for 1/4 mile 4x4 would be and buildup using a NP203 full time Tcase that was designed to be in 4wd in pavement. Do that,throw in some nice gears and a BB with a supercharger do it right and the oil burner guys will be in your smoke. While boosted diesel can make some impressive torque, it is at a low RPM and it has a very limited RPM range for that torque while a blown BB would have serious torque and wide powerband too.  

the 203 is the ticket.. I have a 75 blazer that runs 14.01 in the 1/4 with a martin systems turbocharged 350, th350/203 with 3.08 gears and 30x10.5-15" tires its the stock height and really makes the ricers upset.

BTW... my cousin has a daily driven dodge cummins that blows the doors off of it...

 

Take away 4wd from that CTD and and it would be embarrassed on strip. I know people do it but I would not race with a locked Tcase. If you had a tire or wheel failure at high speed you could easily loose truck and your life too with control loss because tires would not be able to track ground properly once you started to skid a bit and they had different rolling radiuses. A 203 is different as driver is still in full control and with a super charged BB it would walk away for any CTD too.  

I saw a rat motored 77 blazer on the squeeze running 10 11s in the quarter. fast buddy!
i would run some deep gears to git ya off the line and run load range e tires for the heat toughness factor.hooking up shouldnt be a problem. figure out the lbs per horsepower of a favorite car and try to match the 6-6100 lb weight. so 610 horses to match a vette or so. there are fibre glass fenders light wheels,aluminum heads stripped interiors run without the 150 lb top etc  

Is the NP203 what was used in the Syclone and Typhoon? Dad gummit I loved those little trucks!

No it is too big and heavy for those SUV's. The 203 was built for high GVW vehicles. If properly serviced it would take a lot of abuse but many failed to neglect over the years.  

The psyclone/typhoon used one of those viscous drive t/cases like the all awd bravadas(olds) and the like,i cant remember the torque split, but it was like 60/40 or less, so if there is a junk yard???
on the side i figured to git one of those cases- get the V8 kit for a 4x4 and run a zz383 or a world products mouse 454 and go skeer the neighbors! way better than the 300 ft lbs ya got from the factory!
You figure stick a detroit in tha rear of the fierce critter and some sticky 315- 17s drag radials, some bushwhacker cut out fender flairs and wa-la! itle give you the poo pants when the great bugger hooks the 500 + lbs of torque!

Now iffin yourn rollin in the green... gits a zz572 or a 632 from jegs, hooks yerself up to a 1/2 ton jimmy...solid axles then run some 15.50 33's arb the front.detroit the rear and go zoom into the sunset with the cackle of the lumpy cam for them to remember you by..but thats just me.
or.. use the 203 as the same principal,ya got the diff in the middle so as you stage against the nasty ford, ya secretly lock in the front axle then after ya got the 60 foot of outa first, then unplug the locker and go show the ford your taillights...maybe  

PS.. lower the truck, run some stiff springs to combat wheel hop and ya got an auto crossing nightmare!and more aerodynamic than the lifted brick!
now iff your REALLY crafty, go to boniville and put a set of itty bitty gears and run 200 in the mile!  

Actually if you want to get a handle on wheel hop you want a lot deeper axle gears too. What happens is when drive shaft loads up into rear axle, the counter torque lifts weight off RR tire and then it breaks loose and spins and unload that grabs and then winds back up and unloads again causing hop. With deeper gears, less drive shaft torque is needed to break traction or put down max traction limited effort which means less counter torque and less loading and unloading and better balances traction and no hopping.  

Yea, it's totally do able. But why? If you want to go fast buy a car.

Honestly, for the amount of money it will take to get a 4x4 into the 12's you could probably get a Mustang into 9's or lower.  

Snoman- Your knoledge of diesel drag racers is slightly skewed.
The fastest street legal diesel pickup in the USA is a 2WD Power Stroke. I watched it with my own two eyes do a 9.04 1/4-mile at Salt Lake City this year. (By the way, you can watch this exibition for yourself when the '08 Diesel Power Challenge DVD goes on sale)I'm not saying it was its fastest run, but I am saying you don't need 4WD to launch a diesel pickup hard and put down impressive times. It's all in how you set up the vehicle.

In a drag anything you can do with a oil burner, you can do better with a gas motor. Sure there are some that run well but it takes more work because of limited RPM range of motor and extra weight penalty of engine that can weigh up to twice as much. This all started with stock production type trucks and chipped motors and I still stand by that none of those trucks would do anywhere near as well in 2wd drags. Sure you can spend tons of money building a custom one and can with gas too but that was not the point of this thread.  

If it makes you feel better i did a 17.4 with my truck at 78 miles per hour.
