ok this is jus kinda a wild idea but i like to be different..... i already have a 2.8 12 valve that we pull right now but im thinkin about buildin my chevy to pull to..... its a 2004 1500 ex cab z71 reg bed with crap ton of stuff done to, built 6.0l, striaght alxe one tons, the whole works but im tired of the gas burner stuff and cant really do nothin with it but drive it......


wat im thinkin about doin is finding a 96-98 12v doner truck and swaping everthing out...but i have read some rules that state must retain oem drive train so wat im wonderin would this actually be leagal to pull doin this? i mean i have see a crap ton of fords done but never seen a chev that i know of jus wonderin if this might be the reason? jus some thoughts should i go for it or not?
 
This example is from Badger Trucks, but alot of the rules read somthing like this.

Engine block must have been available on one-ton or smaller pickup trucks retain the OEM heads, maximum of 460 CI. Engine need not be brand specific. The front of engine block can be no farther forward than 17” of the centerline of the front axle. (2009)

Body may be any 3/4 or 1 ton full-size pickup truck body. The bed floor must remain intact. The body must retain full sheet metal. Metal after-market hoods are permitted. Fiberglass is prohibited.

Most places allow swaps, just check with where you want to pull, if not lobby them to change the rules.
 
well where we are rules arent really stricked but i was jus thinkin might as well make this legal by most rules if im gonna do it that way if i ever wanted to make any big pulls like shieds or ts i would be good
 
I don't think the NADM and NHRDA rules will allow a straight axle'd chevy in 2.8....must use factory suspension mounting points.
 
you know how they say the tech's decision is final...well it can go both ways, they can also allow certain things under their discretion. I think any tech that wouldn't let a straight axle chevy pull in a 2.8 class or above has something against the driver or brand.

so long as wheel base is retained and the axle isnt pushed way out forward, and it has leaf springs or control arms that are similar to the other brands, and not some crazy long bar setup etc. i dont see an issue. a lot of guys have issues with the IFS and the swap is done to get rid of the parts that commonly break, not to gain an advantage.

Nice truck but you better ditch the lift and tires if you want it to pull very well LOL
 
just a thought

as a tech rep, and class rep, I can tell you I can not make "decisions" that are blatantly against the stated rules - so if the rule says stock suspension mounting points, a straight axle conversion would not be acceptable

I would be asking the class rep, or the tech rep, of the associaitons you plan to run at, and get thier opinion, and in writing, before i went about buildin a truck that may never be allowed to run

well as far as around where im from they pull work stock, 2.8, and run wat you brung... so its not that im worried about it and i know the guy that makes the rules and if they wont let me pul it in 2.8, jus cuz he runs a 2.8 truck, that would be my only problem i see happen lol i would still run it in open jus because....... but really my point in doin this is jus to have a fun cool truck to play with on weekends and hook every now and then i jus like have'n stuff that stands out and correct me if im wrong but i still have yet to see a newer body chev with a cummins
 
I never once had a problem pulling with my setup of the old truck. When I took the truck down to Indy I called the head tech official over a month in advance, he asked to see pictures and said that it wasn't a problem. At the time he said everyone reads the rules different. In his mind and most others it reads..."must be a stock style suspension" doesn't mean 100% that that style suspension had to be stock for that truck!!!

Its hard to say, its not like that axle/suspension setup was never offered by chevy in the past anyway. I was running a Dodge D60 with coil springs and radius bars from a 05+ Ford and I never had a problem.

Here are the the rules on the suspension topic for our "2.8" class

"Front and Rear axles: Any front/rear axle assembly normally available in a 3/4 or 1 ton truck may be used. Swapping from manufacturer to manufacturer is allowed. High strength Custom made axle shafts are allowed. They must fit into an unmodified housing and retain the standard 8 bolt wheel stud pattern"
" Suspension front: The factory supplied suspension configuration for the chassis used must be in place. Control arms may be strengthened. Truck must have at least one working shock absorber per wheel"

- These are probably the most extreme I have seen as far as suspesion rules go but they are kind of counter acting each other and in my mind my old truck would fit these rules. Reason being is the axle was from a 1ton or smaller and although my truck was originally a 2wd I used all stock mounting points for the suspension including the trailing arm mounts which where stock...said I could beef them up which I did.

In my mind its all in how you read the rules and most organizations should except it as long as its 100% safe.

Good luck...Ryan
