Fast 3.23 or higher geared combinations - 07/09/09 08:33 PM
The latest Mopar Action has a 69 Coronet with 3.23 gears running low tens. The details on the engine are very thin, 512 cube stroker 400 with stage VI heads and a small roller cam with an operating range of 2k to 6k rpm. The builder states the biggest mistake most guys make is overcamming.
Can you guys with fast tall geared cars let the rest of us know some details of your cars?
Thanks

Not a 10 second ride, but a member on here (forphorty) has a 68 Satellite with a more or less stock bottom end 440, Id guess compression at around 9 to 1, basically stock 452s, 292 Comp Hyd cam, SD intake, 750 DP, 9.5 inch Dynamic,(Had a GER in it at the time of the 12.30s) with 3.23s that has been 12.30s. Im sure with a little head work it go in the high 11's. He might chime in, but the motor has upwards of 50K on it, I think it has more than that on it.....

I didn't have it on a track yet, so time slips are not available, but my 440 in a 383 block (438 cu inches) was a 9.5:1 unported 906s edelbrock 850 carb w/electric choke, and a comp XE275HL cam, TKO-600 and 3.21s with 28.5" tires, and it would roast the tires in first gear from a 20 mph roll...no idea what it would run in the quarter though--but with that much torque, some sticky tires, I'm sure it could have pulled off a low 13 second 1/4 mile (it's a 4200 lb truck!)
now it's a 4.56 gear'd rear, aluminum eddy heads, holley 750HP carb, and 505hp at the crank, and I HOPE it's a 12 second truck--gotta get it track legal first though--drive shaft loops, etc.

All steel 69 Coronet ? ... low 10's ...I doubt it.
I like the short-gears .... I have a 62 Belvedere with a 440 and a 2.76 gear.
Based on running a Bud of mine ... the car used to run 12.60's ... now it should run 12 teens or so.
Iron Manifolds, thru the muffs ...and get 17 mpg on the hwy.

hey 
You got it almost right Von, except 906s and had an old Torker on it for my best et. 12.35, 106, 1.69 60ft. SD intake picked up about 1 mph but no et improvement. compression is prob 8.5 i guess. TRW 2266 pistons.

I'd have to see a 3.23 geared car run low 10's to believe it. Unless the car has a ton of weight stripped off of it and running nitrous.

gmachinedartGT has a eddie headed roller cam stroker small block in his car with a low gear 904 and 2.94's and IIRC he runs in the 12's, even though the car is setup for autocross with 18" rims....

Thanks for the replies guys.
I will have to try and search for more details on tht 67 Charger.
Domingo, that sounds very similar to my 1st car. A 73 Challenger with a 340 which ran about the same times.
CrazyMoparGuy, what transmission details can you give me.
Jyrki, excellent! Can you tell us the cars weight and some more engine information?

A crappy stock tranny! lol It was rebuilt probably 5 years before going in the Lobster, but it was nothing special. Stock converter too.

Re: Fast 3.23 or higher geared combinations - 07/11/09 06:30 AM
my times are not super fast but heres my set up....
i have a 75 plymouth duster with a 69 383 high performance,
the motor was stock (running good compression on seven cylinders with number 4 at 63 psi)stock manifolds both intake and exhaust,
at the time i ran with a 650 holley double pumper, slightly modded, w/ ram air
727 torqueflite trans with a stock 1600 stall and stage two shift kit,
3.23 gears open 8 1/4 diff,
and the rear tires were BfGoodrich p 255/60/R15
car weight with myself 3450lbs
and my time was....
14.319 w/ 60 ft @ 2.183 and reaction .080
in the last couple weeks ive striped the 906 heads off which had a sunk in exh valve on number 4 and have fixed up a set of 452's as a summer replacement, i got the trans rebuilt as it was slipping in second and partially third, im waiting for a 2600 stall converter, and im planning on throwing on a smaller tire (my old size P225/60R15
(the tire size made a 1 second difference in my car i ran a 14.9 with an eddy and the tires when i threw on the other tires with the same carb it dropped to 16.0, then i introduced the holley, and ram air and ran the 14.3.....)
soo long story short im hoping on running mid to low thirteens when i get everything buttoned up in the next couple weeks

Not real fast,really boring to drive. My Duster street car,SB with approx 375cfm carb running 11.50's@116mph leaving in 2nd gear,about the same as a 2.3 rear gear set and 28" slicks.

Fastest door car I've seen with hwy gears is a 78 Mailbu one of my friends has, it was running 8.50's@155 with a glide and 3.89's, he set it up for powertour a few years back with a TH400 and 3.00's, the same converter from the glide and went 8.7's@158- he lost about 1/10 in the 60' but pulled harder up top.
It's kind of a sleeper since it looks like a typical 80's Pro street but it has a Oddy 540" with an 8-71.

Sounds like he needs another gear 
Don't "G machine dart" run 12s with a 2.94 and a small block or something?

Re: Fast 3.23 or higher geared combinations - 07/11/09 05:20 PM
My Valiant weighed 3530 lbs. The base engine was from my older racier car, indy RB blocked 528, Eagle crank, C&A steel rods, 31cc dished Ross pistons, 440-1 heads with 2.25" intake valves home ported, Straightline performance mech roller cam with about 260 degrees at .050" and 0.65" lift, indy single plane with a Chuck Nuytten pro street dominator, MSD 6 AL, 2" x 34" primary headers and 3" dual exhaust with x-pipe and four mufflers. CR was 11.3:1. Later we drove one season with the same engine in our C-body Plymouth VIP and run 10.6's with it with a PG, 4.10 gears and 32" tires. Because of only two gears it pretty much was equal to the 3.23 gers in the Valiant. The block, intake & heads are still in use in the current turbocharged engine that has pushed the C-body to 8.0's.

408 stroker,eddy aluminum heads 3.23 gear with a 26.6 inch street tire ran 12.99 at 107. It was only getting about 7/8 throttle due to adjustment issues. Plus I was lauching the car all wrong. 727 with stock 340 converter, in a 68 barracuda fastback.

Re: Fast 3.23 or higher geared combinations - 07/11/09 06:12 PM
I know its not a Mopar, but its impressive. Local guy around here.
1970 Monte Carlo, over 500" (555" i believe), car is all steel except the glass hood, with a full cage, smallish tire, no nitrous, 3.23 gears.
He comes to the track, bolts on a set of stickies that he has in the trunk, proceeds to go high 10's, bolts on the radials and goes home. I have never seen the car break, its super dependable. He used to slow it down and run the weekly street night when i raced also. That is a big car to go that fast on that little gear--its all torque.

Re: Fast 3.23 or higher geared combinations - 07/11/09 08:35 PM
My engine is the typical 500" street build. It has a small Dwyane Porter spec.'d roller cam. The et and mph in my sig was done at PRP last fall. The 60’ was 1.87 sec. and DA 1740'. I believe that there is another 0.10 in tuning alone, and maybe a couple more in really good air.
My goal was to be stock-like in every aspect of the car. It idles with 14” vacuum at 950 rpm in neutral and idles at 700 to 750 rpm in gear. The converter is very tight. It drives through the neighborhood at 1100 rpm in third gear like a stock C-body Chrysler. The tranny does not have PTK and will stay in third gear coming our of a rolling stop or turn. Other than the Wilwood front disc brakes, the suspension is not only stock, but original.
With that, I believe that with a 3800lb car, the right cam, headers, and converter and a typical 500" build, you could get into the 10s in a very streetable package with 3.23s without nitrous.

Re: Fast 3.23 or higher geared combinations - 07/11/09 09:11 PM
FWIW, many of the really fast drag radial cars are running in the 7s with 3.42 gears and 29-30 inch tires. I personally know of a Super Street Outlaw NMRA Mustang that has run low sevens at just under 200mph with 3.42 rear gears, 28x10.5 ( non W ) slick, 389ci single turbo ( I think it was a 94mm Turbonetics ) water to air intercooler, and inline valve Edelbrock Victor heads. The trans was a 1.80 Glide.
These cars load the converter hard through first gear. It would be like leaving in second gear for many cars.
A 10 second street car with 3.23s could be done with the right converter and most likely some sort of power adder.

It's pretty easy to run high 12's with a re-rung 440, small-ish cam and 3.23 gears as long as the car isn't too heavy.
A stock 350 horse rated 440 picks up about 50 HP with a simple cam, intake and carb swap as long as the bottom end and valve job are healty.
Pretty cheap, reliable and fun to drive combo.

Thanks for all the replies! The Mopar Action article is not clear to me if he is using the nitrous or not. But if you have it why wouldn't you use it?
What do you guys think the stall should be in a 500+ inch build like this?

Re: Fast 3.23 or higher geared combinations - 07/13/09 06:18 PM
We had a cheater kit too, but never used it at the track. It would have been quite interesting though, it produced quite a kick at around 70 mph on the street with 180 hp jets. I had a 9.5" converter, never checked the stall but I guess it was around 4500-5000. However, it pulled very well even below that and was a real pleasure to drive everywhere. PTC really nailed than one.

That is me and my pops car the article is on. And for all the doubters you can come to NC anytime and I will show you the gears, All steel panels 3700 lbs, or whatever doubts you have. It is a 230 block, stock caps, 440 source girdle, 440 source stroker kit, The old crappy 94 mopar stg 6 heads I cleaned up and worked over a little they flow 308 @ 700, but the cam isn't nearly that big. comp roller lifters, cheap press together pushrods, Harland sharp rockers, Indy intake, The carb is from a roundy round shop near our shop they said it flowed about 920cfm.No cage just 2x3 sube-frame connectors. 2 1/4 hooker super stock headers, homemade 3" x-pipe and cheap dynomax mufflers and not bullets. The converter is a 9.5" dynamic converter, flashes about 3800 with .065 nitrous jet and has been the 10.26 @ 134 with the 100hp of nitrous and has been 10.70 @ 125 on raw HP. It is sitting in our garage right now for any doubters.

Heads-up, thanks for posting some more details on your car! I like it! Would you consider using an RB with a 440source 528 or 543 stroker kit for a build like this?
Shaker223, boost is your friend! Can you tell us what kind of time and money it took to get your slant to go like that?
These lower buck builds are cool, do we have any more?

My street car 500" 590tq 511hp ran 12.10 with 3.70 gears. Couldn't stand 8mpg! Switched to 3.08 and still ran 12.30. Big torque down low doesn't care much about gear. Speed up from 110 to 112! 64 sig car loves 4.89, might try 5.13. Different animal.

Re: Fast 3.23 or higher geared combinations - 07/17/09 04:32 PM
Was talking to friend about this that runs a glide. Figure his first gear is 1.80 with a 3.89 rear ratio which makes him a 7.00 total ratio thru first. His sixty foots are in 1.3 range.
727 first gear is 2.45 and if you use a 3.23 that would make your first gear a 7.9 ratio.
The torque convertor would need to be set up for the higher gear ratio.
