Not to hijack but does anyone know if this is at the M1 concourse. A friend and I are going to bring a 67 belv. over As far as I know it is not at the M1... its on Woodward right near South Blvd.... I'll be at the M1 concourse 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

Put some pinion angle in the rear. I had mine down on my old Duster about 5 degrees( with S/S springs) and the thing hooked on ice. Made a huge, huge difference just adding that shim. What in the world does pinion angle have to do with making the car hook? Absolutely nothing........Some old timers would say pinion angle helps it "throw" the pinion more at the hit. None of it's true

None of it's true 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.

None of it's true 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.
Mopar to the bone!!!

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.

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

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
