As far as I know it is not at the M1... its on Woodward right

EDIT
Might be right in front of the M1 concourse..
I am hoping it is..... all I hear is it might
be south of the railroad tracks(the tracks would
be past the shut down area)
I still dont know if they will run south bound
or north... if its south it would be right in
front of the M1.... at least I think its gonna
be there

Absolutely nothing........Some old timers would say pinion angle helps it "throw" the pinion more at the hit. None of it's true

I drove through there the other day... it's gotta be south of the railroad tracks. To hilly/bumpy in front of the M1 concourse itself. But that could be the staging lanes, and then the starting line would go south from the corner. All of the festivities though are at the M1 concourse as I understand it.

Just about got my 5/8" studs in the car... time to start testing!

Exactly. Has nothing to do with leverage. It's just to compensate the spring wrap up, so the pinion doesn't go over zero angle.

I ran in kc , had a blast. If I do it again I'd add weight to the back
Sand bags so they could be removed. I walked it out on the bit about ten
Feet the stabbed it . My first pass spun bad with no nitrous so I knew it wasn't
Gonna work .
70 coronet. 440 iron head . 600 lift mech cam, 150 shot.
4.56 gear . Assassin bars. Adjustable ranchos.
Bring a lot to top/mid range if wont work down low.
Nobody was doing wheel stands that day.

The car will hook in 2nd gear for sure on the street (from a roll), so my guess is even if I have to launch soft on 5psi, and can only get 10~12psi in it through 1st gear, I can pour the power to it in 2nd and be rolling through the traps.

It's only got a 3.55 gear too, so that helps.

Anybody know how fast the quickest non-dodge was in KC? I heard they ran 600ft there, and the quickest dodge was like 6.70's.

I recall reading some stuff in "The Big Car Magazines" where some street racers (early fastest street car types) talked about adding pinion angle to soften the hit off the line. Never sounded right to me, but they were running way faster than me.

Have you thought about making a hole change on the caktrac bars to try and soften the hit.

The one that won ran 8.70's in Kearney with his Trans brake inoperable. He lost to the white Firebird in the video on the first page that ran 8.50's. Troy is going to Detroit to.

As stated, front end loose, rear set around a 50/50 setting, if leaf springs add pinion angle, put weight in the back, radial will be tough to hook, come out the hole soft and roll into the boost. A bias ply would be better but I see not in your cards right now.
I had a 1993 Dakota with a 408 and 275 shot of juice that I grudged race back in 2010. Made a good bit of money off it with 28x10.5 tire and stock suspension. Asphalt will want a lot of rear squat and power brought in easy, I doubt the trans brake will work very well on the asphalt, I always foot brake mine.

Lower caltrac hole might be an option if it spins right off. Need some test data...

Scott, since this is no prep... dont be in any
early pairs.. hopefully they will put some rubber
down... about all I would expect is them using a
power broom on the track and that would be all

Last year at the silver dome, we had the Monkey's Dart and Kill Charger laying down some skin before anyone, so that may have helped a little. Traction was a bit funny if you laid into the coals too much.
I've had some experience running on limited stock tires against other cars back home and it was all in the loafing of the foot. Took a few lunches away with good coordination.
I suspect that this surface will be a little more forgiving but just be wary of the other guy as well. I say this because my car got stinking drunk and I sailed from one lane to the extreme other on my first pass till I got a good burn out factored in and soften my foot jab into it.
Make sure your brakes are in good shape and most importantly, study and sear into your head where the actual finish line is, it comes up rather fast and then you have to be into the woe along with Elvis.

It was just short of 1/8 mile , like 630ft.
My buddy Doyle Hanvey(purple challenger wedge motor) who came in second
Was running in the 6.60-6.45 range spraying two kits.
Which I've seen that car do no nitrous on the track .

Impossible to make a leaf car "squat" plus that's not what you want to do anyway. The suspension has got to extend and stay extended to plant the tire and keep it planted. So this would indicate the extension softer to hammer the tire more, especially with lower power level and as stiff on the bump as you can stand to KEEP it separated. If the extension is really lose and also the bump, it will just throw the housing and let it come right back, that's the reason for stiffer compression. Many think loosening the front way off is the way to go, but you have to be careful that it snatches the front up and tops the shocks quick. If it does that you can bet it will spin the instant it tops the shock. So while a lot of travel and maybe weight in the trunk to help percentage is a benefit, super loose front settings will NOT be the hot ticket. Regardless of surface, you still have to CONTROL the front and rear. Super loose everywhere gives no control and will just be action and reaction that you have no control over

If you launch on the street and the front tires have any weight left on them, you are not getting all the traction possible. But the goal isn't just to jerk the front tires off the ground, you want a smooth transition. Super loose front settings need to be accompanied with the right front spring. I generally want my front spring to un-load at about the same time that the suspension tops out, to minimizes any upset that the chassis might see at that point. A super soft spring that has to be compressed to be installed is not what you want.

With lots of front travel, it's important to do all you can to minimize bumpsteer.

uuummmm OK, but me personally have never had "super loose" work at any time or any place
