Re: The Tail Moves Violently Side to Side Above 100 MPH

No. Bias front, radial rear, but the car was sashaying with bias slicks too. I’m going to the track next weekend. I’ll update then.

Re: The Tail Moves Violently Side to Side Above 100 MPH

How is the panhard bar set up? I'd pull the shocks out and see if everything is moving freely and not binding because of some geometry error. Check the welds on the axle tubes going into the 12Bolt. No panhard bar. Diagonal link. That’s a good suggestion, checking the axle tube welds. Will do! Ques...

The Tail Moves Violently Side to Side Above 100 MPH

‘71 Nova, back half ladder bar, Koni single adjustable 12 bolt, 10.50 big tire car. Old race car I’m bringing back. Nicely done in it’s day but needs attention now. It just started recently to vigorously shake the tail side to side. Not up and down. Balanced the tires. Then I found the forward rod e...

Re: Quench safety distance for a 496 MAG gen 7 BBC

While searching for an answer to my question: Expected change in quench distance from cold to operating temperature with Dart little m iron block and aluminum heads this thread popped up. If you guys don’t mind I’d like to add my two cents. Another factor to consider is the condition of the machine....

Re: Mid 10's street car NA?

4L80 also requires a stand alone controller in your application. More money. If you do get to 700 hp or 600 even, you're going to need an anti-roll bar. Without it you may look like this out of the hole: https://m.youtube.com/watch?v=w6jo6gVug48

Re: F body drag racing suspension questions

No, it wasn't Spohn, BMR or UMI. I've learned quite a lot during this quest. I've come to understand the engineering relationships relating to instant centers and anti-squat, setting the pinion angle with a driveshaft inclinometer and the satisfaction of solving a vexing problem by my own means whic...

Re: F body drag racing suspension questions

Found the problem. The design of the aftermarket torque arm, from a well respected manufacturer, put the rear suspension into severe bind. So I made my own based on a slider link. First time out today with this setup - 3 passes 60' foot within .003. Finally a working suspension. My confidence going ...

Re: F body drag racing suspension questions

Re: why a tight converter? Basically it's what I had. I had success with it and that was the bottom line. Now that I can compete at higher levels, I see that converter selection should be my next area to address. Re: lots of mods. Yes, lots of mods. The stock suspension requires alot of mods IMO to ...

Re: F body drag racing suspension questions

I have. I was hoping for something more than I received. I realize S/SS racers work hard for their results and just don't give away their secrets. I was looking more for direction/recomendations/education on the 4th gen 3 link from guys who have been there. Is Bill Shope still contributing on Speed ...

F body drag racing suspension questions

On a points day prepped track my car is very consistent (thousandths) for incremental and split times. It's when the track is less than good I have issues. Also it doesn't take much to provoke wheelspin downtrack on a suspect track. After having the same car as mine go by me on the bumper during tim...

I know it's been a long time since this thread was originally posted but the True-Trac is a sore point for me. I have a Moser 9" w/4.11's and T-56 in my 2001 Z28. The rear is first thing I changed when I decided to go racing. The sales pitch on the True- Trac convinced me to purchase it. With 473 rw...

F1 – yes that is the picture. Mr Shope. I’m quite excited that you have taken the time to respond to my inquiry and more so that you don’t think there is anything wrong. I went to your website and reviewed the traction dyno chapters. I do have access to scales and the measurements could be taken. So...

Travel Limiters

I am bracket racing my 2001 Z28 with rear lower control arms relocated and adjustable shocks F/R, 250 lbs. drag front springs and front sway bar disconnected. Judging from event photos I appear to be getting good chassis separation in the rear but extreme front end travel without wheel stand. For a ...
