dont know if your track separates the big tire cars from the street cars on T&T nights but if they do, try to get behind a few big tire cars that will lay down some rubber and avoid the street car lane like the plague.

I tried going around the water box and backing in...Even avoided it completely. Always been hit and miss.
Too much gear for the tire
Too much air...something ?
1500rpm is about as high as I can go and have a chance(off idle works best). Tried 2000-3500 and it didn't like it at all Crying or Very sad

Been down to 12 and as high as 30 with all points in between.
Track prep is the key and I will not go on a Wed. or Fri. nite TNT again due to all the problems (oil downs,breakage,fart cans)...Saturdays are the $hit Smile lots of passes,fast cars,great track prep,and plenty of light to make changes Laughing

How much movement do you have in the front end? John Calvert says you should have a minimum of 5 inches. I had to trim the snubbers on my upper control arms.
I also loosened and pal nutted the control arm bushings to let the front end move easier.
One other thing I did was replace the ball joints with Afco units. They move much easier.
I looked into trick front coil springs but Moroso told me that at 3714 with driver (I'm 240) my car was too heavy.
I've never used Drag Radials so I don't know how they compare to my ET Street Radials. I drive them on the street as well. I tried running regular street tires but I didn't like the tires blowing away everytime I gassed it.
If you can get your car to hook I would think you'd be easily in the 10's with a decent track, especially on the bottle.
We have an exceptional track at New England Dragway. I love running on Wednesday afternoons. It's a T & T limited to 25-30 cars. They treat the right lane and exclude street tire cars from that lane. Street tire cars run left lane only. I don't believe they do any track prep for Wednesday nights. They don't allow slicks on Wednesday nights. Friday nights are better. Best times to race in New England are in the Spring and Fall. The track is around 90 feet above sea level and when the weather is good I've seen it way below sea level. Only problem is when the DA is great the track usually won't hold.

If you have the shocks set to 90/10 the car is up and then down too quickly unloading the rear tires. I'm suggesting the lower shock setting and tire pressure combination.

Front shock changes are worth a shot. Personally I haven't seen much difference with the fronts. Much more with adjusting the rears. I just think you are going to have a really touchy combination with the converter and gear you have with the drag radials. Going to a 295 tire will help - wider but the height will help too by taking some gear out of it. Does somebody have a set of slicks you could try? I think you'd be happy with the results. Clay

Had McCreary's on the rear (bias ply) and really didn't like the loose feel on the top end or the "squirmy" feel on the street at 35psi.

Maybe a radial slick ? Laughing

One thing that could be part of your drivability problem is the rear springs you have. Over the years I have run stock monoleafs, Landrum monoleafs, a 5 leaf multi and finally bit the bullet and bought the Calvert racing split monoleafs. As the power increased the car started driving worse and forced me to upgrade. I'll have to say the Calvert racing split monoleafs drive WAY better than any other spring I have had on the car. Before I would never run less than around 15 - 16 lbs in the slicks becasue that's about all I could handle. Now I have gone down to 12 and it does pick up a little sway but it's still not as bad as the other springs with 15 - 16 lbs. Now slicks aren't going to drive as good as radials period, it's something you will have to get used to but your springs may be part of the problem. Clay
