Need more info. Motor size, trans, convertor, weight. There is one thing that I don't think you have right. There are no secrets it is just basic.

One thing you will NOT regret purchasing is a pair of AFCO double adjustable shocks for the rear. You need the ability to adjust rebound and bump independently.

The other thing that has been mentioned is a 30" tire. Very good idea.

How easily/smoothly does your front suspension work? Have you worked over the bushings so there is no resistance or bind? This is absolutely critical. Consider some Del-A-Lum bushings. Have you cut any coils off your Moroso springs? I would imagine that you have since you've got a SBC up front. Consider some Santhuff front springs. www.santhuffshocks.com You're probably looking at 160 or 180 lb/in units. They will provide maximum weight transfer.

How much travel do you have up front? You need a minimum of 5". If you don't then you need to cut the upper/lower bump stops and get the car sitting lower in front.

Just a few things to think about.

What are your current ET's? What RPM are you leaving at on the brake? Based on your low 1.5x 60 foots you should certainly be able to hook consistantly.

Re/ Slide-a-Link bars. We've had success with these using a re-arched stock monoleaf but replacing the entire two piece bar and poly bushing with a fabricated single chrome moly tube threaded to accept the supplied ends. Getting rid of the flex and distortion helped, as well as lowering the rear pad 1" to alter the angle on the bar. A bit of preload on the right bar and neutral on the left worked on our Nova with 60 foot best of 1.41. Strongly recommend the double adjustable shocks as well. If you were starting from scratch, I'd probably get the Cal Tracs instead, John Calvert is great to deal with and helpful from my experience....

5+ inches of travel in the front.
I have tried launching anywhere from 3000Rpm to 4000 and nothing works. No coils have been cut out of the springs, front end is as free as a can be, bump stops are all the way out. When the car works it runs high 7.30's-7.40's 1/8th mile.

9 x 30 Goodyear radials, in a D-4A or harder compound, with a light burnout.
One tire compound does not fit all tracks or conditions.

Thanks Goob I'll let you know, I am still tossing around trying a Glide but I dont want to be on my back every week changing it and I dont want to have to spend 2 Grand to have one that wont break. My car is about 3400lbs isnt that to heavy???

As i remember from another thread you posted several months ago you mostly bracket race your car. The set up you have in your car is more of a street type chassis setup. You will not get the kind of performance or consistancy you are looking for with the chassis setup that you are using. I would suggest for you to install a rear frame section with a 4 link or ladder bar suspension using a coil over shock. I have HAL single adjustables on my car. I think this will be money well spent. You can go to a wider tire which will help on the marginal tracks. The powerglide will give you the consistancy that you are kooking for. If you have a decent trans with race quality parts you will not have to touch it for a whole season. The point I am trying to make is if you want to have a race car you have to set it up like a racecar and use race quality parts. The stocker guys use some of the similar parts that you are trying to use. They spend countless hours perfecting and testing their combinations. They do not run their cars weekly and they replace the tires on their cars very regularly.
