I run a truck 12 bolt right now, Eaton posi, Moser 30 spline axles, Richmond gears, LPW braced cover, welded tubes. I'm planning on going to a narrowed Moser 9" with a Detroit locker and 35 spline axles, disc brakes.

What I don't like about the truck 12 bolt, is I don't want to run a spool, and you can't get a posi carrier for anything larger then a 30 spline axle.

I used to run a truck 12 bolt...spun the axel tubes then rebuilt it as strong as possible. Worked fine but I went to a 9". If you have a true 600HP than high 10s should be possible if you have the right converter and gearing.

600hp at a total weight of 3500# for him to run high 10's ?

Jim, what have you done to get your truck down to 3500 w/you in it? I have a 66' Chevy lwb that I run, and it weighs 3820 w/me and 8 gal. of fuel. I run the lightweight seats, no heater box or wipers, alum. headed sbc, and a bolt-on 'glass cowl hood. I haven't changed anything like control arms or the like, basically because it's not in the budget right now. It still has the factory inner fenders because the hood hinges bolt to them. It's cool to see some other guys draggin' these old trucks!!

[71Dragtruck]

If you go back a page or 2, I posted a link to pics of my 4-link. There also is some pics of Jim's setup, and it looks like he just used the outer skins of his box to build the bed. Looks fast sitting still, I'm sure he'll respond, I just wanted to comment that he for sure has taken it to the next level of drag truck building.

[nxtruck]

Thanks for the reply! I did see a pic of Jim's truck on a pg. or two back, but all I saw was an outside view of it. It does look good, as well as does yours. I saw a pic of yours on another thread. I'm glad to see that I'm not the only guy tryin' to get a long wheelbase, nose-heavy pickup to 60-ft. respectably!

[71Dragtruck]

I guess I should have looked closer, pretty sure I saw some pics of the inside of his box some where on here?

[bigjimzlll]

heres some..I lost atleast 200lbs with stripping the bed and tailgate skin. I cut the front frame horns off as close to the steering box as I could. Disc breaks instead of drums. fiberglass hood and roll pan. aluminum heads and radiator. Aluminum electric water pump and ofcourse any thing not absolutley needed is gone.

[nxtruck]

Hey Jim, thanks for the reply and the pics! You've really done a lot of work to your truck. I would imagine between the bed and the rear frame, there's a lot of weight gone! BTW, nice lookin' mill under the hood! Seein' your dzus tabs on your fenders reminds me of the pin-on hood that used to be on my truck. I ran it for about a year until I finally got tired of having to get the wife to help remove the hood every time I needed to work on it! I finally decided to put a bolt-on hood back on it, even though it was a little heavier.
How much of a difference is there between your ladder bar setup and the trailing arm setup? Or did you run the truck with the trailing arms? I still have trailing arms under mine, although I did put an anti-roll bar back there along with some Rancho adjustable shocks. My truck has cut a 1.55 60' on the motor so far, and that was with a 30 x 12.5 ET Street. I have since put some 31 x 14.5 ET Streets on it, and hopefully I'll see an improvement with them. Thanks again for the info...

[bigjimzlll]

I went with the ladder bars for adjustability. The trailing arms work great but since I was changing rears and narrowing it, the ladder bars were easier. I have 60' with trailing arms 1.59 and with the lighter truck with ladder bars 1.48.

71dragtruck glad to see you have got the truck back on the track! I have been in new trailer (28ft enclosed) and tow truck mode so I haven't been to the track in a while! I did the unthinkable and bought a Furd Tow truck but it seemed like a steal its a 99 f350 crewcab short bed single wheel powerstroke and I only paid 10k for it! I think I hurt the convertor when I sprayed my truck so I have to send it off and have it redone! I also found out the truck weighed much more than I thought. Its 3286 with me in it!

[71Dragtruck]

I was wondering what happend to you, been waiting for you to post up some 8-9 sec. nitrous passes. I also bought my first Furd this year ( hang my head in shame ) but I needed a tow viehicle that could handle the weight, and new Chevy's don't cut it stock. Hope you get back on the track soon, lot's of drag race guy's are following your build. Mine suppose to go in for a roll bar this month, have my belts, tranny shield, just waiting on my seats and then taking it to the 10's.

[djracer]

I haven't made a 1/4 mile nos pass yet but I did go 6.05 with the wrong convertor I hope to improve that soon. My best motor pass so far is a 6.53!

[bigjimzlll]

Tow vehicles????? I drive mine daily on the street...I do get some extreme looks though. That's whats nice about double adjustable rear shocks...set them loose and it rides like a cadillac...turn them up at the track and your good to go.

On a side note...I found some race shocks for the front(fits stock mounts and locations) Qa1 rc 1574p is the number. Summit number is HAL-rc1574p...very very nice and adjustable

[71Dragtruck]

I saw those front shocks, if you try them out let us know how they work. I think I'm going to break down and get some QA-1's for the back and get rid of the non-adjustable. What length you running on the back, and what rate spring did you have before skinning your box, or what were you running then, I can't remember what you had with your stock arms.

As far as tow vehicles go, closest track is 2.5hrs. trailer is cheaper in the long run with the price of C12 and supreme. The truck plays double duty for work, well I admit it's over kill for what I do.

[bigjimzlll]

Right now I have 14" Aldan DA shocks with 150lb springs. I might be a tad over sprung. I had 120lb on with non adjsutables and it worked well. Never had coilovers with the old set up.

Time less than 11:50 requires a roll bar sysetm? Is a nice et for a pickup. Good luck with future drags.........

[smoknbarrels]

wondering if u drag guys can help me out a little..
my truck will be mainly street driven, so i wanna keep the stock swing arm suspension. but I am debating putting a 6-71 on my 454... it's only a 2 bolt main, what kind of hp can I put to it with a cast crank in it?.. i'm new to the bbc world, and want to go faster then the 350's i'm too familiar with. or should I just stick with a carburated high compression engine. will it even hook up with 295 radials? or should i look at a different set up..
high 12's kinda speed is good enough for me..

the thought of a nice polished mailbox sticking out of my hood gets me thinking though...!

[djracer]

A tow vehice might be cheaper than the 116 octane fuel I run! I want to be able to travel and race out of town!


A good set of coilover shocks with the trailing arm and a drag radial should be good for traction! I don't know much about the 6-71! The huffer would be sexy sticking out the hood!

[bigjimzlll]

Smoken....If you have a low compression BBC 8-1 or so a blower would be kewl. If you keep the boost down. A cast crank is ofcourse a time bomb with a blower if you race it. To run high 12s you only need around 400HP(true HP) not DD2000 or magazine HP. A nice 10-1 hydraulic roller 454 or 468 can get you there.

[djracer]

I spent too much time washing trucks and I only got one pass tonight! It went 6.63 spinning pretty bad only a 1.52 short time!

[nxtruck]

I took my truck to the track last night for some testing and went a 7.13 @ 96.15 w/a 1.57 60' in the 1/8. This was a motor pass. I have a '66 Chevy lwb with a 421 sbc, TH350, truck 12-bolt w/4.88s @ 3820 lbs. I have an NX Gemini quad plate on the motor, but haven't tried it at the track as of yet. With the amount of wheelspin that I had last night, I'm considering trying a P.G. trans. to calm some of the spinning and also to be able to spray the motor hard out of the hole. Do any of you guys run a 'glide, and if so, did you notice much of a difference from running a 3-spd.? I know most people will say that a 3-spd. would be a better choice in something this heavy, and I guess I could take some gear out of the rear. I have a set of 4.10s in the shop that I could try.
This is a cool thread, BTW...

[71Dragtruck]

Good job guy's, I can't wait to run mine on a prepped track to see what I can 60'. Missing races again this weekend who invented work. Yes I like the drag threads also, wish they would have kept Djracer's stickied.
