Anyone running down in the 11's or even 10's with a 3.55 or even 3.23 gear? give a little detail about your combo,

That's a good question.
Can't answer yet.
Have 3.54 and will be testing next year.
I'll keep an eye on this topic.

Plenty of hard running combos like that I'm sure.
My 3815 lb. 67 Belvedere has 3.55s and a 255/60R15 Drag Radial
Runs 12.80's in the 107-109 range with a mild 440 270/470 hydraulic cam, CNC ported Stealths, 750DP. 1 7/8 headers with 2 1/2 inch exhaust.
73/73 in the Big Shot plate and it's went a best of 11.30-122. 11.76 on nitrous with 2.76 gears.

11.30 @120mph
68 Satellite 440cu.in 5lbs.boost
3.33 ratio Dana 60
Stock converter, 1.72 60ft@hr on street tires etc.

Car in sig is kinda close. Not low 11's, but mph suggests it has potential. I think it is reasonable to think my car with a 2400 rpm converter, headers, and a 200 lb. car diet would put it in the low 11's.

The car's 60 ft is 1.90 sec, and the converter won't stall past 1800/1900 rpm.

Dizuster has been 9.62@139 with his turbo small block. 3.55 w/275 radials at 3750+

We will have one this year....3700lbs with a fresh built 440Source 526 stroker in an RB block....Plan is to switch to 4.10s for racing, but we might take it with the 3.23's he streets it with and see what it will run. Our guess....11.50's



And just to pick on you a little....It has to survive more than one run.....I watched one of your 9s vids, very impressive, but I would like to see it live a little more than a pass or two at that ET. I am thinking, a 5.7 hemi is in your future and 9.50's or faster...

you dont need headers or a diet........put a converter in it low 11s no prob with 120mph.i bet it would be in the 10s with all the above.what cam u running?

Seriously? Not to speak for him, but I believe he has been bracket racing the thing. If going rounds and driving on the street isn't proof enough, not sure what is...


Not low 11's but 11.50 @ 116
66 Belv. 493, -516 iron heads, .530 cam, 9.5" converter, 3.55's and a 28" tall tire. I have a plate on it but have yet to open the bottle up. The converter is probably a bit loose, but I expect high 10's with a relatively small shot.

6.09 @115 with 3.23. Factory exhaust manifold equipped Sb.

69 Satellite, 493, unported E-heads, 256/585 solid, 6 pack, 2" Hookers, 3600 stall, 3.54 Dana. 4120 race weight, 28" slicks, 11.48@117, 1.69 60 ft.
Ran 11.80's w/1.78 60 ft. on regular Goodyear Eagle GT-2's walking it out.

511 ez-1s 67 gtx 3.54 3800 race weight with me ran 10.90s

If I recall, when he surpassed my Duster's ET and posted the vid, it let go on the next pass or two...Don't know how many passes he logged before the nice 9s pass, but I am still impressed how a mild 360 street car keeps up and even surpass's my pump gas BB race car.

Me, I woud take all I learned, and go 5.7 stroker/392 Hemi and turbo, put a glass hood on it for weight transfer, and run low 9's all day. I think he has it all figured out at this point.

It's all a learning experience. Who else has gone that fast with a stock block sb in a streetcar. Between dizuster and I, I'm pretty sure we're going to test every limit of a stock block sb. I know what mine broke at with no fill or girdle,and 2 years of many miles of street abuse and easily over 100 passes and I firmly believe with a tall fill and a girdle it will go 8s this year at weight (3650) safely


I know he talked about going gen3 hemi, and I don't blame him. If I had the funds I'd be doing to same thing, but I like these ratty Ole small blocks, and they're cheap.

Thanks. You are probably correct, I just didn't want to sound too presumptuous.

First a converter...... Then some tires

First time out:

11.75 @ 117

Horrible 60 ft. of 1.78. (Cold track, misting off and on) leaving off idle.

Pump gas through the mufflers on street tires with 2800 stall converter and 3.55 gears.

505" RB with Stealth heads, Holly Street Dominator and very small Howards .544 lift hydraulic roller.

I'll do better this weekend!

It did break ,but didn't "let go". Best we can tell the porcelain was damaged during plug gaping. It broke loose and was rattling around on the center electrode. With no path to disperse the heat it became a glow plug and nipped the #1 piston near the valve notch. The tune up wasn't that radical. On a VERY mild tune it'll run 9.90@133 forever, been doing that with no wounds. On inspect during tear down #3 rod bearing showed signs of detonation but the other 7 looked good. Remember this is still stock cast crank, stock 360 block, stock truck exhaust manifolds, no intercooler at nearly 3800lbs. Street radials, steel wheels, full stock interior. 2014 Monster Mopar ran 10.0 shoot out and Pro. Made it to the final 4 in the shootout and the final 6 in Pro before a trans leak sidelined it. Plenty of 9 second passes, plenty of street miles, heck Dizusters mom has taken it to Church.
Doug

A little update. My car ran an 11.30 @ 119.8mph this weekend.

The mph says I have an 11.0 waiting on me if it ever hooks well!

Not the gear ratio you asked about, but very poor gearing. 3400 lbs, 535 cube stroker,5000 stall, 906 heads, 4.10 gears, 33x15x15 slicks, left in second gear by mistake. Went 10.60 on a 10.40 dial. Equals a SLR of 5.945. Same as low gear (2.45) with a 2.42 rear gear! I remember winning the round, too. The other guy spotted cords hanging out of his slicks and dialed up a full second in a panic! Racing in the eighties was easier than today!

Ha ha...I just caught this thread. Mine made around 80-100 passes in 9.90 form last year, as well as lits of street driving.

Still learning, but something happened and it nipped the piston. Either the plug damage, too lean, or too much boost. I'll take the blame for the tuneup, but it wasn't the parts fault.

Just about back togetter with a new slug ready for BRACKET RACE season and terrorizing the neighborhood.

Mag'd the cast crank and checked it for straightness...good to go!

8.93@149
3.23 geared 8 3/4
5.7 Hemi 88mm turbo

Last year I blew the 4.30s I had in my car and put 3.23s I had laying around and my 60ft was still the same 1.50 and the et was still the same, usually 6.9 to 7.2s. That's in an 72 dart with a 499 with a 3,200 stall. I did put shorter tires on 275/50 15 in place of the 295/65 15s. I was shocked to find out it ran exactly the same.

I agree as you have the power for 11.0's at 120 mph. Conveter and some chassis tuning and you could be in the very low 11's. Ron

I just found this thread, and it gives me hope! Thinking about taking my Duster to the track this year with 3.23 gears, 28" drag radial, and 9.5" converter.

Do any of you know your trap rpm?

S

Whittled down to an 11.1 @ 121 mph end of last season. Trying to resolve rear suspension issues.

yeah, I like this thread. Right now, the parts I have are pointing to me building a 451 low deck for my 67 coronet. Thinking about the heads right now and was wondering if the 240cc (trick flow or cnc promaxx) would be too much volume.

I see some guys with cnc stealths in this thread so I guess the ported heads would be ok. That leaves me with the possibility to step it up to a large cam and more gear if I decide I want to get more serious about haulin ass...

I'm thinking 3.55 gears are the sweet spot...BUT, I have a 2.94 sure grip in the car now so maybe I would setup a 3.91 third member and if I want to take a longer trip just swap the 2.94 gears in...idk.

2.94's would be sweet on the highway. I don't care for my 3.23's on the highway but most guys wouldn't mind it at all. I had 3.55's and hated them but they'd be better on the strip.

Go for the better Heads so you have room to grow. My motor is a pump gas 500" with CNC max wedge Edelbrock's. It has a small cam and small headers, seems to have alot of torque so I'm hoping to hit high 10s or low 11s driving to and from the track.

I ended up hitting the Belvedere with a 0.051 N2O jet. It ran a string of 10.95-10.98 once I got the timing where I wanted it, before I got a talking to for no roll bar

It had a 10.8x in it, but the track was going away and they shut it down before I could get the launch sorted

Car is 3700# at the line.

I basically use it as a daily driver during the 2 month MI summer...

I have been 9.70 with my 493 at 3300 lbs with 3.55 gears, this combo would have went 9.50s but decided to change directions without ever getting the slip
I have been 9.88 with 426 g3 at 3240 lbs with 3.55 gears

Impressive, sure would love a car like that in my garage.

Very impressive Ray. What RPM do you trap at? 275/60/15?

Im thinking both combos are under 6800. Ive have either 325/50 or 295/55 on my car

Awesome! I thought about doing this for the upcoming season as well. What did you set your total timing at? Did you change spark plugs to a different heat range?

With a 28" tire, 3.55's, and a mph of 136 I'm getting only 6000 RPM's, which sounds about right to me. Are you running naturally aspirated?

11.57@116.2
4,008 pounds
3.23
93 pump gas
9x28 M/T pro bracket radial

I have been 10.91 with 3.54 gears but my 5-speed has a 3.37 low gear so that makes for a nice mechanical advantage. I will be interested to see how the car reacts with a 4.10 gear and a 2.66 low gear in a stock HEMI box.
Last time out I was driving through the clutch which was indicated by the 126 MPH. with an 11.09 ET. Someday I will get my clutch tuned but I don't spend enough time at the track to get it dialed in on kill.
Gus

It seems with the torque alot of the strokers have they run fast with not as much gear. And the shorter tires is like putting a high number gear in so that may have also helped keep the et about the same. Ron

NA. My 493 was 140mph. The 426 135

Last summer, 11.02 in a '71 cuda with 3.55's and slightly modified 6.1 SRT hemi, and it will run better, something was holding it back. http://kuvia.1g.fi/kuvat/2016/FHRA/Night+Race+Finals/Saturday/MOP_4385.jpg

And around 2004 10.31 with 3.23's, Indy headed RB on pump gas, 3500 lbs.
http://kuvia.1g.fi/kuvat/Tapahtumat+2007/BurnOut+Party+25.8.2007/25.8_07+204.jpg

I think I ended up with 28-30 degrees 100 octane unleaded (O2 sensor for the EFI and Lead don't get along). NA with pump gas I run 32-34. I went 1 step colder plug, non-projected tip.

I accidently left in second gear with my Dart many years ago. BIG stroker (for the day!) The dial was 10.20, I ran 10.45 flat out. Loose converter though. A lot depends on that converter being loose enough to be high in the horsepower curve. If it isn,t that will really hurt ET. Leaving in 2nd was like my 4.10 gear turned into a 2.70!!

About 4 years ago I broke the gears I was running and stuck some 3.50 gears in my D50 with 315/60 Drag Radials. I was surprised that it did not slow down very much. It ran a 6.39 at 109 crossing the finish line in 2nd gear in the 1/8. With a 1.39 60 ft. Wallace racing calculators says that is around a 10.10 in the 1/4. It is a 394 ci small block running on pump gas (93 octane) through the mufflers with No power adder at 2950 lbs.

I was doing that in a true street radial race this summer. 100 lbs. over the rear bumper, leaving in 2nd and best time was 11.94 @ 121 mph. Very hard to hook a stroker with a 275 street tire!

I used to run true street radial at my local drag strip years ago. Best I ever did with my old 511 and 3.23 gears with 275 tire was a 6.45 in the 1/8th. The brand of tire that I ran was primewell or mastercraft. I would buy a set and do burntouts until they were halfway worn and then they would start hooking good. I would do a half throttle take off and ease into full throttle in 1st gear.

This RPM calculator has always been real accurate for me for the street and the track, but I've never raced with highway gears. Does this look ok to you guys? About 5450-5500 RPM's at the 1/4 mile stripe with 3.23's, 26" tall slick, and 'thinking' my car will go around 127mph.

I have a 9.5" converter that seems to flash pretty high so I think it will work with 3.23's. If I use a 28" 275/60 Radial I could go to 3.55's but I sure do like the 3.23's when we cruise to a car show an hour or more away from home, I hated my old 3.55's.

I don't think 1/4 mile ET will be much different between a 3.23 and 3.55 but I've never tried it before. My previous cars all had 8" converters and 4.56's.

Saw one of your other posts about setting up another pumpkin. Was going to suggest you try/use a 26/10 slick instead. But, didn't know the actual tire diameter that you are using now to compare.

But, yes, a 26" slick would work perfect IMO for your car and gear combo. No need for another pumpkin IMO.

You wont quite have the gear that a typical 4.56/32 tire @ 127 6080 RPM, would have. But still not to bad with your 500ci, that a 3.23/26 tire @ 127 5301 RPM would give you.

I agree Mike, I think it will work for a street car that might se a track twice a year. I currently run a 28" 275/60/15 street radial on the street so I figured a 26x10" slick would be good for the track.

Bob, when spring comes and your ready to try some 26/10,s, I have a set sitting here mounted, that Ive used on my dart. Your welcomed to try them out.

OK thanks Mike I might take you up on that offer.

9.0s @ 160 at 3600lbs 3.54 gear. Shooting for 8.0s this year

You're cheating! Kidding, love your car. You easily have MPH for 8.80's already I would think.

Ya its a fat pig to get rolling then it chatters the tires well into second gear. hoping to get that all fixed this winter.. Its coming too fast!!

1967 Barracuda HT, 410 SB, 3.23, 28" tire. Ran 12.34 @ LVMS and 106. I was a little leam. I think it will go low 12's and around 110 at Famoso. Drive it to the strip race, and go home. 15 MPG on the road.

Bringing this thread back from the dead. Can't wait to see how much slower my car is now with 3.23's.

This thread made me decide to go with 3.23 gears in my Duster awhile back, I finally got to drive it to the track this year and it went 10.69 at 124.75 with a 1.51 60 foot. I'm extremely happy with it.
500" low deck, 10to1 compression, small 557 lift purpleshaft cam, Eddy cnc ported MW heads, 950 carb, small B-body 1.75" headers, mechanical water pump and fan, never runs hot.
727 with Dynamic 9.5" converter that needs tightened(17.5% slip), 8.75 rearend with factory leaf springs with one new leaf added to each spring, Rancho adjustable rear shocks, 275/60 drag radial.
Launch at 2000, shift at 5800, trap at 5800.

Sounds like a great Drag Week type combo.

I drive it a lot and go to car shows over an hour away, drove it to and from the track a couple times. I should probably start a new thread on this, but I'm curious of your input and others input on my 9.5" Dynamic converter that's slipping 17.5%.

Normally I prefer an 8" converter with about 3% slip but in this particular street car this converter feels great on the street and strip, so I would not be very happy if I had it tightened up and it hurt performance because of the 3.23 gears. If this converter was tightened to around 5% slip the car may run better and MPH better, or maybe not....

THE 56 has been running 11'S ever since I built the 493..has sidewinder OTB heads from Marsh, has a small hyd roller cam 530.530 lift from Bullet,is 3400 lbs plus my 200 lbs,, best 60 ft 1.69.. best et is 11.38 @ 119.5 mph..3k stall converter. 3;55 8 3/4 Just pulled the motor ,putting it in a light weight, ------..gonna sell the 56

Been 9s with 3.55s with a 493 and g3 hemi

I really like my 9.5 Dynamic converter I run. How tall are the rear tires you run with the 3.23's at the track Bob ? Ron

28" tall, 275/60 drag radial.

That is an impressive combo

I posted this elewhere, but we got a new best of 10.69 @ 128 with 150 shot last Saturday. DA was well over 4000 ft. and it was at least 85°! May put the 200 jets in for tomorrow night... or

Nice runs CSK and GY3!

I guess this was a while back! We went 10.01 @ 133 last Fall.

I've been 8.97 at 152.5 mph w/ 3.54 gears at 3900 lbs.
I've been a good bit quicker since then, but I've only been going to 1/8 mile tracks. Hopefully get a new 1/4 mile timeslip real soon.

What size tire you running Chip?

295-65 drag radial...about 30" tall.
