Search for the 10's with my 67 Charger.

[womanator]

Put the Charger back in the shed today.
Putting on the M-1 manifold seems to have solved the bog.
Roasted the tires for 50 feet with no hesitation or stumble.
Next week I'll get it to the track and see if I can get it to 11.49 et.

 

[Budnicks]

Womanator Sounds great, good luck keep us posted...

 

[womanator]

Ok Budnicks,
Went back top the track and made a couple of pass's.
The good news is the stumble is gone completely.
The 60 ft times have gone down to 1.63 sec.
But my 1/4 mile times were 11.93 to 11.95.
Ran 3 pass's and they were all right there.
Speed was 111 and change.
Shifted 1-2 at 5400 and 2-3 at 5600 and going threw the traps at 5800.

I guess it's time to put on a larger carb than the 750.

The car doesn't fill like it wants to go over 5800 rpm.
Cam is the Comp Xtreme Energy cl21-228-4
.241 int/247 ex @.050
.545 lift on each.

As far as the carb selection goe's
512x6000 divided by 3456=888 cfm's
Or
512x 6500 divided by 3456=962.
I'm leaning towards the 950 size carb.

I'm going to leave the converter alone,the 60 ft times on leaf springs and Hoosiers at 1.63 is fine for now.
Chime in with your thought and anyone else's.

 

[Budnicks]

950cfm sounds about right, probably the easiest too, or you could go to a 4500 Dominator 1050cfm & proper matching "ported" Intake Manifold, 1"-2" carburetor spacer & heat isulator.... Good Luck

I was toying with the thought of taking the Dominator off the Dart for weekend to try just that.
Was putting The 68 back together this weekend and put a NOS plate on to see how it would fit and decided to put a fogger on instead.

The other thought was to get a king demon with diff sleeve's and try that.
Have you used one before?

 

[RustyRatRod]

Put this on it.

No Demon's, I had friends using a few, I used Holley's, Holley HP, Quickfuel, Promaxx or ProComp stuff 2300, 4150, 4165, & 4500's... I personally like the Quickfuel Technologies stuff, even on street/strip cars, but they also gave me some carbs too, over the years, when I was racing regularly, so I'm a little biased, I really liked the split 4500's w/4 2bbls basically on a sheet metal tunnel-ram, Top Gun N20 & CNC/ERC Fuel Systems {both gone now I think}, w/3 kits, plate kits under the carbs {custom made that wasn't cheap}, a spray bar mounted permanently thru the center of the manifold, then Fogger Nozzles pointing directly at the intake valves & roof of the intake port runners... I could use either 1 or 2 or all 3 kits or any combinations of the 3 kits, if at a great track or 1/4 mile with sufficient shut down areas, I could go as high as 500HP on spray bar & fogger nozzle kit, only 250HP on the custom 4 x 2bbl kits, never that much thou, tracks & car couldn't hold the power, I would leave on the Carb Plates as soon as I let out the Clutch or Trans-brake, depending on what type of trans I used, at what time, PG or Clutch-glide, Torqueflite or Clutch-Flite {didn't last} or Jeffco/Lenco w/Crower slider clutch, the Spray-bar came in about 330ft or 2-2.25 seconds, fogger nozzels came on about 660ft or 5-5.25 seconds, all progressive start out low pressure 250psi & build to full bottle pressure 1000+psi, with ignition retard/N20 custom timer {my partner Rob was a electronics wiz}, latter I switched to Blown Injected Alky & 526ci later, much easier on parts, allot less fiddling around with tinny N20 & Fuel jett's, 3 fuel systems, burning off plug tips etc... You know all the fun stuff.... 301ci-377ci SBC & BBC 427ci-540ci, N/A, Carbed or just Mech. fuel Injected, stacks or a Enderle Inj. Hat on a Tunnel-Ram & sometimes Blown Inj., some BB Wedges or Max Wedges & Hemi's 500ci-540ci Aluminum "old" Milidon Mastodon, in sizes from 383ci-479ci B Low decks, to 426ci-572ci RB Max Wedge heads, N20 or Blown Injected, SBC, BBC or Mopars, 6:71-12:71 Roots & Whipple Screw type Blowers... Most of this was between 1981-1997 & some stuff as late as 1999-2000, I just dabble/play a little now...

 

[womanator]

If I go with a fogger I'll prob get it from Steve Smith.
Not sure what I'm going to do with the Dart for now.
Going to play with the Charger for a while.

 

[Budnicks]

Sounds like your having fun....

 

[womanator]

Going to the track Saturday with a 850 Holley and see if it picks up top end speed.

Will let you know.

 

[Budnicks]

Good luck...

 

[womanator]

Well the guy that was going to let me borrow the 850 didn't show up,he had truck issues.
So I decided to jet up the 750.
I went from 73 in the front to 76 and 80 in the back to 83.

Here's the time slip.
The car picked up et and mph.
Still gaining.

The other car ran 10.50's look at his 60 ft times.
Ladder bar car.

 

[Budnicks]

Sound like it wants more carb to me too... the 750cfm {or even the 850cfm if you can still get it} can still improve it even more, yep maybe with more acc. pump discharge squirter, more acc. pump cam, more jet's, possibly different &/or better flowing metering blocks, at a combined minimum... the 850cfm to 950cfm tunned correctly would probably be the "right carburetor" size, it looks like to me.... I had an old Holley DP 950cfm 3-bbl, that I loved, I sold it many years ago now, to an old racing buddy, he still uses it today, I went to a Dominator at the time, wish I would have kept it, but the 1050cfm Dominator, investment worked out well thou...

 

[womanator]

The new year has arrived and it's time to up date my Charger.

Still shooting for the 10's.

I'm taking the stock Eddy's off and putting a set of Edd'y that flow 42 cfm more than the stock one's.
The worked over Eddy heads have 75 cc's so that will raise the comp ratio from 9.52-1 to 10.44-1.
Changing the cam to an old comp custom cam #23-000-5.
.607-622lift.
Changed the carb to a 950 Quick Fuel Q carb.

Going to keep the the 3.91 gears.

Damn that sounds like a big improvement, better/bigger carb & more flow more compression, just the head flow is worth something like 2.06hp/per cfm of flow; 2.06hp x 42cfm = 86.52hp minimum improvement, or more if tuned/done properly, then the bigger/better carb, bigger/better camshaft & higher compression, will add a few more too, probably around maybe 120hp or more total added, with the new combo now... good luck, have fun

 

[womanator]

Made a mistake on comp ratio.
Pistons are a -17 cc dish not -27 cc dish.
So my comp ratio was 10.15.
Now with 75 cc champers the comp ratio should be 10.93-1

Engine out of the car.

Not very good picture,but here are the ported heads with 75 cc chambers.

 

[67gtx 0324]

Well I removed the old engine and trans.
Took the headers to be re-coating,side note here they charged me $200 to remove the old coating and $300 to coat them.
Engine and trans I was told had under 100 miles.
The trans was supposed to be rebuilt with kollen steels alto bands kevlar bands and bolt in spag and to my suprise it was.
My tranny sponsor tore it down and gave it a clean bill of health and the only thing we did was installed a Cheata manual valve body.
It has a 3000 stall convertor.

Took it to the track a few weeks ago and it ran a 12.3 second pass at 111 mph falling off at the b1/8 th mile.
Next 2 pass's it ran in the 13's.
Put in on the trailer and took it home.
Why run a broken car.

i would think you would get that car in the 10s with that motor 5 years ago i had a 67 rt with a 472 motor auto and 410 dana, with mufflers, pump gas, cal tracs and drag radials 4000lbs street car
would drive to the track and go 10;50s to 10;70s 124 to 126mph. depending on weather the car was in mopar enthusiast magizine

Better pic of the head.

I admire your perseverance. How much does this thing weigh? My bet is 4100+. Your gonna need a fair amount of cam,compression,gear and converter to hit your goal. My bet is 3.91 isn't enough. I'd bet 12-1,[email protected]" cam,5000 stall,4.56. Or lose 500 lbs
Good luck Doug
