Ok, I really love posts like this and I have a mild street/bracket combo for my limited budget.
1972 dart swinger, stock front bench and rear seat with no carpet giving me 3400lbs with me in the car.

I use a 440 with the stock cast flat tops, steel crank bottom end and windage tray.  I think the compression is around 8:1 with the unported 906 heads and steel shim gasket as the cranking compression was around 90psi.  It must be the low compression that allows me to use 18 degree initial timing and 41 total with a stock electronic ignition.

The 906 heads have 2.08-1.74 valves, crane ductile rockers and I use the .509 purple shaft.  I get the exhaust through schumacher tri-y headers with a short extension pipe.  I installed the cam straight up.  I run a street dominator intake with a 1" open spacer, crossover blocked with the valley tray, and 850 double pumper with 50cc pumps.  The engine is held in place with the 3/8" jegs elephant ears and a front to rear limiter. 

I use a stock gas tank with 3/8 pickup and line feeding a high volume mechanical pump.  I use and electric water pump, aluminum radiator and electric fan also. 

The 727 has a manual reverse valve body and a 9" 3800-4000 turboaction stall converter.  The front suspension has /6 torsion bars, 90/10 shocks, and disconnected power steering.  I made a set of frame connectors from the info on the tech page.  The rear is a 68-69 B body standard width dana 60 that I had 3.73 gears installed and a pinion snubber.  The rear is held in with the 002/003 superstock springs and long mopar drag shocks.  I use the stock 14" polyglas front tires and the rear are 26 x 10 ET drags with tubes on 15 x 10 weld wheels.
     All this is good for low 1.7 60 foots, 7.8 1/8 mile times and 1/4 mile times in the 12.30-12.50 range with 104-107 mph at Quaker City raceway here in Ohio.  This is a very basic combo and my first mopar project.  These cars are very easy to get into the 12's using stock parts.  I can't wait to build another.

[383man]

Well mine is no race car as its a street car I drive when ever I can including driving it to the track. But here is some info about it.
It's a 1963 Ply Sport Fury with an all stock body that I put a 6 point rollbar in.  The leaf springs are the original ones and it has air shocks at this time until I put SS springs on it.  It has a basic 440 that I built to sorta look like  Max Wedge but I dont have a crossram yet. It is a stock bottom end 440 thats .030 over and has a stock crank and rods that I bushed for the KB quench dome pistons.  I use 906 heads I ported and cut to get a nice .042 quench and a street friendly 93 pump 10.0 comp.   Has the MP .557 cam and Isky iron rockers.  The Holley Street Dominator intake with a basic 850 DP.  A Mallory dist with the MP orange ecu box.  Hedman 1-3/4 headers and 3" exh with Dyno Max Ultra Flow mufflers.  I built the 727 with mostly stock Mopar parts and use a TA reverse manual valve body and a Dynamic 9.5 convertor that flashes about 4200 at the track.  I have 4.30's and use 29 x 11.5 Hoosier QTP tires.The interior is stock other then the rollbar and the car weighs right at 3700 with me and a 1/2 tank.  It is the stock gas tank and I ran 3/8 line and use the Holley red pump.  Only ran the 1/4 one time so far with a best of 11.66 @ 114 but it was a very hot day and I love racing it so I will be going out soon in the cool weather.  This is a cool post as I really enjoy reading about the cars.      Ron

[64 Dart in a Donut]

even if i get made fun of, i have a 64 dart with a 4-speed, 73 340, 70 heads, 318 forged crank mild cam, 273 drivers exaust, 318 passenger, dual plane intakle and a 770 vacuum secondary holley. besides the holley it was built in the early 80s and needs to be rebuilt. it has an 8 3/4 rear with whiney 3.55 gears w/ posi, and 50 $ pep boy tires. the closest quarter mile is 4 hours away, ran low tens in the 1/8 mile without power shifting, losing traction in all three gears i could get to. not one person i met down there was running a manual, people who noticed me lose grip every shift would wait at the timeslip booth to check out my primer dart. it was my first time and i am 17.

[ksdartguy]

Well this is my new setup, so I have no numbers to backup yet.

400 block bored .035 with 4.150 440 source kit 499ci. .010 down deck
with ported big valve 346 heads milled to 85cc for 11 to 1. Still waiting on cam,
but probably cam Crower roller, 262/266 @ .050 with .686/.692 lift with HS  1.5 rockers.
Comp 919 springs, TM6 old edelb manifold with 790 Holley E85 carb. It could use more,
but I had this already calibrated for e85. I also have a small plate NOS system I may use. 150HP.

Beefed 727, A&A VB and 9" J convertor, just back from PTC to be loosened to around 4200.

Truck Dana 60 that had 3.54s, new stange axles and spool with disc conversion.

Car went 10.90 @ 123mph, with the old 383 procharger motor. It weighs 3600 with all steel wheels and
My heavy (large frame)  in it. Still assembling it all as well as moving the springs in for a little more tire room.
275-60-15 drag radials now.

1 3/4 ttis into full 3" with X pipe and magnaflows. Thats about it.

[blackbetty]

Everyone here seems to building drag cars. Mine is going to be a roadracer. It is a 71 Dart that will have a full 2x4 box frame and 14pt cage. Corvette C4 front suspension and a custom 3Link rear. The wheels I have are 17x9 for the front and 17x10.5 for the rear.  I am using a 9" rear with 3.55 and Detroit trutrac. The trans is a tremec t56 with upgrades to handle 600hp. For now it will have a stock 400 with twin turbos but after I get the turbo system dialed in I will change to an all alumium motor. The interior will have sparco racing bucket seats and stewart warner guages.

[quickd100]

I'll throw a curve ball at you guys. The truck in my signature, with the $300 440 in it, it ran a best of 1.595-60ft., 7.621-1/8, and 12.19@105.88-1/4. The truck weighed 3550 and ran 4.56 gears and had a 38.5 square foot frontal area. (lot of air to push down the track)
  Fast forward to now, new motor, new rearend, rollbar. The engine specs;
528 hemi, cast iron mega block, cast iron heads, SS valves, GOOD valve job, ports just cleaned up. 10.5-1, cam is the old MP 614/598 272/274@.050, 104 centerline installed @102. Deep 12 quart pan, milodon duel line system, tray with scrapper. JE custom pistons with .990 pins, Manley sportsmaster 6.965 rods, bobweight, a portly 2642. ATI dampner, V series bearings, Cloyes hexajust, SmithBros pushrods, Comp cams springs&retainers with Manley lashcaps. Weiand tunnel ram with 2 900+cfm modded thermoquads and ram air,  2-1/8"x34"x3-1/2 equal length headers, 18" collectors, 5000 stall, 4.56 dana with spool, caltracks and 10"x 30" slicks. I haven't weight the pig yet but I estimate it at 3800 lbs. I've been shifting it at 7000 and it hasn't hit it's hp peak yet.
  So guys, what are your guesses, what will it run? Dave

[maxwedgedart]

hey, quick 100 putting the hemi in is only about 100lbs heavyer then the 440 your truck should run about 11.20@116 in 1/4.

[quickd100]

MWD; I believe if it doesn't run into the 10's there's something broke, but maybe I'm over optimistic. The 440 with just some of the old MP recs bolted on exceded the MP predictions. Dave

[68_GSS]

QuickD, I guess the mid tens.  Just think what that Hemi would do in an A-body.   

[quickd100]

QuickD, I guess the mid tens.  Just think what that Hemi would do in an A-body.   

 That's half the fun, nobody expects much from an old truck. Nobody expects to find a stroker hemi under the hood. Dave

[maxwedgedart]

hey quick  that hemi  you built looking at the specs. i do not think it will even make 600hp and the camshaft is the wrong specs. for that hemi. but good luck with it with spray maybe 10s, but thats what we mopar enthusiasts do what ever it takes to go faster! thats the fun of it right.

[maxwedgedart]

hey 68 gss, that hemi in an A-body would not even come close to my 68 with the maxwedge 440! and my knuckles are not suffering from bleeding hemi knuckles! thats a good thing.

[quickd100]

  I'm not going to say you're wrong until it's been down the strip on a full pass. The cam though is the same cam that the old MP recs recomended for 426 ci hemi all the way to 10 flat. Granted I've only got 10.5-1 compression but I've got 102 more inches, and a better induction system than what they showed in the recs.  I know a guy on the east coast that runs a 528 crate motor with a new crossram, that's the only deviation. The car is a 65 b body at 3500 lbs., he runs 10.20's or 10.30's with it.
  I guess time will tell, I can't tell you much about 1st or 2nd gear as anything past light throttle in those 2 gears results in instant tire smoke. Generally above 60 mph it will hook, the top of 2nd gear and high gear are brutal. Dave

[maxwedgedart]

hey, quickd do not get me wrong i think its cool as hell your truck with a hemi, i also like to be different but as a realist just to go 10.90 at 3700lbs you need a min.565hp to the wheels and at 3800lbs you need about 580hp to the wheels and 650hp at flywheel thats not as easy as you think. and you said 1st and 2nd gear half throttle breaks the tires loose, so that to slows you down so you have to figure out how to get the truck to hook! you need a good 60ft time need to hook and book. shifting at 7000 or higher your not going to get longgivity out of it you should dyno it so you know trk curve and at what rpm your max and averge hp is at. to get your converter right for the truck. you might find your self shifting at lower rpm to stay in peak hp and trk range all the way down the track. these are things you need to think about i know i am 45 and it did not come to me over night. one more thing your said the motor was 10-5-1 comp, mite want to try to come up 1 more comp point  11.5-1 is good for a healthy street hemi. "keep truckin'

No I'm not trying to bust your chops and I've taken no offence, I'm glad to get your input. Maybe I should back up a bit. The truck hooks better than a lot of cars at the strip, it's high center of gravity really helps tranfer the weight to the rear wheels on launch. With the old 440 it had 67% of the weight over the front axle, even with that much weight over the front it still picked the front off the ground about 8" leaving the line. When I talked about it smok'in the tires that was with the street truck radials that are on it. 265/75R15's. You bolt on a set of slicks and get to the strip and it hooks like glue.
  Anyway, time will tell, I'll let you guys know, good or bad how it turns out. Dave

[maxwedgedart]

hey quickd, ok caltracks is good transfer is must, you really only need about 550 to the wheels at 3650lbs  to go 10.90s at about 123 or 4 even 3700lbs at 575hp 10.80s @ about 125.  i think thats possible if truck hooks like you say you only need to make that horsepower to the wheels stay with it let us know and if i can help you in any way just ask!     RICK!
