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.

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!

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...

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.:rolleyes: Yes I like the drag threads also, wish they would have kept Djracer's stickied.

Yea, it's a tad heavy for a glide. How tall of a tire do you run? I run 4.86's but I run 1/4 mile. I have 32" tall tires. While hitting the N20 You need to load the engine...lower SLR (staring line ratio)(1st gear ratio times rear gear ratio)will help. With the stroke of your SBC I would look at taller tires or 4.30 gear ratio while spraying.

hey bigjimzlll
did you know that you can get a 200# loss in weight by running a fatman front end. that 200#s off the front. so i have read anyways. i am goning to atempt to build my own front cross member i dont think it will be that hard. does anybody know what the widest rack n pinin is. i mean out of a differant car or truck.

Every time I look at the front I know it...It drives me nuts... We were looking at a nova front half...should be pretty simple to swap. I just spent a ton on drop spindles and front disc's.

Jim, I run a 31" tall tire. You are correct; you definitely need a lower starting line ratio when spraying. I guess I'm trying to figure out the better way to achieve it. I'll probably end up putting the 4.10s in it and trying that.
Talking about the Fatman front-ends, that is also something I'd like to do. It's going to have to wait a while, though. Got too many other things to buy first.

I run a glide with a 4.30 gear! My truck has been real fast with the previous owner! I'll get there one day! best so far of a 6.05!

I don't know about anyone else, but I'd say that 6.00s in an old Chevy truck that can be street-driven is pretty quick!
Since I already have the 4.10 gear set, I'll probably try them first and see what happens.

My truck is barely streetable it has a race weight glass nose and doors! It also is 14 to 1 so gas would be rough!

Your truck is for sure at another level, Jim's truck has to be pretty close also. I'd like to get my roll bar, few more race parts, hood etc. maybe alluminum bed and that will be it for me. 10's is as far as I'm going, can't be bothered with all the hastle of 9's, next time my motor is out I'll likely change it into a 540. I want to run low 10's on motor, loose the nitrous ( it will be there for show ) and at the weight I'm at going to need a bit more oomff.:) Maybe fuel injection.:rolleyes:

I just got my motor back and cant wait to go play..Sold my nova streetcar and havent raced anything in 2 yrs so I going nuts reading these threads..anyway What are you using for a driveshaft..and do you still have the center support bearing???

Depends who your talking to. Mine is custom made, 1350 yolks, 3" 2-peice, with a heavy duty support and a splined rear section with a slip yolk.

Mines all aluminum 1 piece!

Mine is a 3"DOM custom job. I used a long tailshaft th400 and move the engine back 4 inches to be able to go one piece.

http://imagehost.bizhat.com/users_thumb/6169/thumb_dsc00524.jpg (http://imagehost.bizhat.com/show.php?id=143702)

The support you have Does it bolt up in the same place as the factory one or did you have to make somthing?

I have a 4-link setup, it has a custom cross member and the support fastens side to side, if that makes sense to you.

Here's the only pic I have of the back piece.

Thanks I forgot about the four link. By the way I gotta say your truck and the others in this thread are some badass trucks. I think seeing one of your videos got the idea in my head to race my truck. thanks

No problem, keep us up to date on how your making out.

409biscayne...'67, 11 second quarter @ about 120 mph and was told not to come back until he had a roll cage. 350 4-bolt on gas. Neat truck but the body panels did not fit...now I know why...too many wheel stands...LOL! This truck has been for sale ever since I can remember!

I'm a '68 w/bb . :)

Franks72, I changed my driveshaft from the factory 2-piece to a 1-piece. I had twisted a couple of slip-yokes on the 2-piece and had gotten tired of that, so I had a 3 1/2" 1-piece shaft built. I had to do some clearancing to the hole in the crossmember that held the carrier brg., but nothing major. Pretty well a bolt-in swap.

I would definatly use a 1 piece shaft!

I wanted to get a 1 piece, but nobody wanted to build one that long, they said it wouldn't hold up.

I think that the 2-piece shafts are stronger than a lot of people think. I always heard jokes from my buddies when we were at the track about seeing parts of driveshafts coming out from underneath my truck on a pass, but it never happened, and I went some 6.70s in the 1/8 with that setup. I finally got nervous enough about it and put the 1-piece in it.

Mine has been good so far, hope it holds up. It is made of heavy duty 1350 series parts and makes the stock shaft look like a tooth pick.

71, if you're running 1350-series parts, then you're definitely running better stuff than I was. All I ever ran was the factory stuff. About every 2 years or so, I'd put a carrier brg., u-joints, and a slip yoke in it. Never had any trouble out of it.

hey djracer
did you get your torque convertor problem fixed? have you been running? haven't heard from you for a while..

I have the old one out of my camaro in it right now but I have to get the other one redone to be able to spray it! This one seems to run about the same but I don't want to kill this one!

anybody run this weekend? I just took my two boys and a friend down the track!


Meathead found me glass bedsides and a tailgate now I got to go to Tn.

And details on the glass tailgate would be???????? Where, weight, how much.

No racing for me, seats are suppose to be in this week, and mine is going in for a roll bar. Have all the parts now to run 10's.;)

I didn't run this weekend. I'm trying to figure out a high-rpm vibration that seems to be drivetrain related. What do you guys run as far as pinion angle is concerned?

Too damn hot to run here..over 110 and we are getting ready to shoot the primer. Going to install the new converter and ultimate playback tach. We are 2 degrees down with the ladder bar set up. I'm going to drop the barsdown one hole to try and get a good shot of a wheelie.

Good luck with the new mods! You need the roll cage! The glass stuff is super thin and just a skin!

yea...but...where and how much????? I used a tail gate skin(after market) pretty light and cheap

Meathead found this stuff in Tn but its new never installed. I think its probably from U.S. Body source!

I didn't think US body had bedsides....complete beds yes..I'll have to look into it.
Nevermind..they do...not cheap though:O

Hey Jim
I finally got my truck to 1.99 60ft , not exactly down where you are , but ....
Do you think i would benefit from some front drag shocks ? I'm running new gas da stock replacement from Napa . They seem much stiffer than the rears . Thanks ...................................... 409 .

are you spinning? What converter? are running the slicks I sold you? Sub 2 second is getting there. What was your MPH

anybody run this weekend? I just took my two boys and a friend down the track!

I did not run at the track but we did get the supercharged beast fired up and ran down the road. It is going to be sweet. At 40 mph I gave it about 3/4 throttle and it left a 20ft long patch and was gone. We still have to play with the timing and carb. It hit 5lbs of boost and I have it set up for now to do 8lbs of boost. I might try the 10lbs sooner than later. Sorry to highjack the thread, just excited to finally drive the beast.

are you spinning? What converter? are running the slicks I sold you? Sub 2 second is getting there. What was your MPH Not spinning that i can tell ,does shudder a little , 2400 street fighter , on your slicks , mph only 92. It;s been hot here as well , so et 14.42 - 14.49 ish.
409 :)

Front drag shocks wouldn't hurt(except the wallet) but I don't think you will pick up much. When I first started I ran 14.57 at 87mph, so you do have some ET left. Have you played with tuning yet? A quicker advance curve with a higher total timing should help the short time. What distributor are you running.
You can always call me at 530-945-8975

Right on, JIM'S DRAG TRUCK HOT LINE !!!!;)

Good job breaking the 2's.

Just remember, when looking at your 60', it's not like a car, that's alot of steel your trying to move. I've taken alot of car's that out 60' me, I have good reaction times, so cross first so you don't notice unless your watching the clock.

You thinking of going to glass bedsides Jim? I wonder what US body's cab weighs?

You have to get that thing to the track, slap on a set of slicks and see what she runs. We need to know details like that.:)

Nope on the bedsides. We talked about it last night. I can remove and install my complete bed by myself. So I figure around a 125lbs. 2 bedsides(outer skin only) and a tail gate skin. So I can't justify the 1000.00 for the glass stuff...and it may even weigh more. I am going to email US body and find out how much the glass doors weight...our doors are real...real heavy.

Anyone that needs help or wants to compair notes..or just say hey can give me a call...I have like 10,000 roll over minutes I need to use...lol

Post us some pics I'd love to see your ride!

Let us know what you find out about the doors. The pics you showed of your bed, that's complete? You just have side skins and tail gate skin no front, with framework? What do you run for a cover? I've often wondered if a aluminum floor would be worth the cost, I want to lighten mine up, but would like to keep a full bed.

Morning guys
This is my favorite thread . I'm running the factory points distr , with 38 degs of timing , no vac advance , i do have a 6a box and msd distr i could swap in . Whatta ya think of a 75 shot of NOS ?
Not trying to hi - jack , that's my last question . :)
Thanks ....................................... 409.

Don't think you are trying to Hijack I revived the tread just to keep it going feel free to ask all the questions you want! If you have forged pistons I'd add the msd and the nos!

The glass doors I have are way lighter than aftermarket steel! I can easily pick up a door with one hand!

I don't really know what pistons i have , i've never had the heads off . I would guess there the stockers , everything else was . I need to get this big fella to 13.99 , so i can race bracket 4 . Lots of cars in bracket 4 , only about 7 or so in bracket 5 . I'd rather not get too deep into the motor at this time , better in the fall / winter.
Later .......................................409. :)

You would probably be fine as long as you don't detinate it! I'd start with the msd!

Bigjim

I'd like to see more pics of how your bed is attached and interested in what you run for a cover if any!

Yes all questions are welcome here, it's the new drag truck discussion thread. 409, a little trip to Canada you could pick up my old motor, it ran 12's;). For sure drop in that MSD stuff, must need with the NOS.

Thanks for the info Jim! 409, I know that if you're careful with your tuneup, a stock shortblock will take 125-150 hp hit of spray. Like I said, though, you really need to look at all of your plugs and make sure that it's not detonating. Go 1 step colder on your plugs and follow the nitrous company's advice on recommended fuel pressure. Also, take out 4* timing for every 100 hp added. This will get you close. BTW, the MSD will definitely make life easier when adding the spray.

Just got off the phone with Marty Chance of Neil Chance racing convertors I will be sending off my 9 convertor in the next day or two to get it checked out and tightened up!

Hope that will help my times on the spray! It may hurt off the bottle but you got to give a little to get a little!

Yup thats my complete bed. It mounts with 2 studs to the cab..2 mounts in the back and 2 out riggers by the wheel well. I have an aluminum bed cover made from 3 pieces of .030 aluminum. Mounted to 1x1 square aluminum tube. With the back panel piano hinged.
The truck is at the painters right now...when I go over I will take some shots of the bed mounting and cover..b4 and after install.

409...a 75 shot will sure wake that puppy up...yeeehaw

dont know how many people do this or maybe its been talked about earlier.. but there was a truck that had a custom rear bumber made from rectangular tube and the guy put a little hole in the top to fill it with a 100 pounds of lead said it helped with traction greatly..:blah:

Thanks for the pics in advance BigJim!

If these trucks are setup right they hook pretty well with out adding weight! The rule of thumb is every 100 pounds is a tenth of a second! I need to eat less cheese burgers!

Post us some pics I'd love to see your ride!
DJRACER,
I will get some pics soon. My fuel cell has a leak so I pulled it and I have just a few more things to get on it. I need to cut and buff it again as the last guy did not do a good job at all.

71Dragtruck,
I have the slicks sitting here ready to throw on it. I will be out there soon. We are shooting for the dyno at the end of next week as well. We are hoping for high 10's low 11's. I need to hit the 10's so I can get my new personal plate 10SEC71.

hey bigjimlllz

please can you post the bed pictures. come on i wana see....:o

Well if you don't get in the 10's I might have to use your plate idea for mine.:lol: Just kidding, hope you make it, and in one piece. I would like DRAGTRUCK but too many letters maybe DRGTRK, DRAGTRK, DRGTRUK, just don't look right. Maybe DAMFAST;), or an idea from 20 years ago WICKED:buh:

I'll get pics as soon as I can...It's just too damn hot to go out. Over 110 all day today.

On the tag thing..I was thinkin just "YES" yes it's fast...yes i'll race you..yes it's street legal...yes i'll take your girl friend....

I might need to get one that says 8secpu After a little more work!

I might need to get one that says 8secpu After a little more work!

That thing of yours get's any faster than that you'll have to get one for good luck that say's THISIDEUP.:lol:

Thinking SEEYA would ge good also.

How about likmygat

I think I like them both DAMFAST and THISIDEUP.:lol:

409(Doug) The headers and new exhaust will be your answer. lol:lol:
Just kidding. I think the 150 shot on yours and it would be the ultimate sleeper. It looked like you had some good lights a few weeks ago when I was out there.

What are you guy's running for race seats? djracer I see you have Kirkey seats in yours, what size are they and how do they fit? I'm a larger guy, 6' 1" around 250lbs. farm boy build :lol: I ordered in a set of cheap seats but they are fairly small in the seat part, not too bad on the back little tight in the ribs. Likely ok for a 1/4 mile and a bit of cruising, but still thinking of the Kirkey seats. The place I get stuff from has 17" in stock, had one 18" but gone now, need to decide by tomorrow night if the ones I got are going back or not. Leaving Fri evening to get my roll bar in, I guess what I need to know is how do the Kirkey seats fit.:confused: Looked at the measurements on thier web site, but also thought the ones I got would be fine from the measurements. Don't really want the RCI type plastic ones, They ones I got are a sports car type, not too bad for weight, but for sure heavier than full race seats.

I think I like them both DAMFAST and THISIDEUP.:lol:

DAMFAST on the back, and THISIDEUP on the front.;)

i'm using a cheap RCI type....and I'm 6-3 290lbs

I think the kirkey's I have are 17 inch! I am 5 10 210! I love the kirkey's they fit the truck and my butt quite well!
