pulling truck

dose anyone have a pulling truck they wana share some info on or post some pics

i have a 1980 gmc k3500 cab and chassis and i found a shorter frame i would like to put the cab on to meet the wheel base limit this is going to be an all out pulling truck. the frame is from a 78 k20 its got a dana44 and 14bolt and i have a bigblock and a small block laying around and when i do my tranny swop the old 4 speed will go in this still have to get a tailshaft and t-case to bolt up to the 4 speed and a clutch peddel but that should be eazy to find

the only other reason of getting this frame is because i bought the gmc for the 4x4 parts but my crew cab is too long to pull with inless its an open pull with fue rules

on this frame im thinking about welding the rear axle to the frame and putting a ladder bar setup up front with coil overs and hopefully a cheap set of 15" wheels with diffrent off-set so fornt tires stick out more and i have cheaper tire options

any other tips/tricks?

Re: pulling truck

What class are you going to get it initially set up for?

I would immediately start looking for a D60 up front and lockers are a must front and back on a pulling rig.

You will probably have to have 3 rings around the rear drive shaft and 2 on the front, and you will have to have a kill switch, which that is an easy fix. Your flywheel will have to be a steel billet with like a 40,000lb tensile strength and an SFI approved bellhousing or scatter sheild, any exposed u-joints will have to be shielded all the way around.

I would start out in one of the stock classes and work your way up, cause it is going to take some major bank to have a competitive pulling truck, believe me.

Almost all the lower classes require cast iron heads, and depending on what class you are in will determine if you can have any weight sticking out past the front of your front bumper.

A lot of guys cut the bed floor out, the key is to have as little amount of weight in the back and as much weight as you can put up front weighing down the front.

I would def get different offset wheels and some guys will cut there rear axle tube down making it narrower all together.

I love truck pulls, been around and involved in them my whole life. With the huge popularity of diesels it is making quite a comeback. I am sure there is something I am missing, just focus on u-joints, chrome/moly axles and a good dual disc clutch. Get all driveline components from the tranny to the ground taken care of FIRST, then start making some major upgrades to the motor, other wise you are going to be breaking things left and right, well, you will break things no matter what, but whatever you can do to help is good. Good luck.
