I'm currently running hoosier 31.5 12.5 W 15, stiff side wall, have had good luck with them for bracket racing, the problem I'm running into is keeping the front end down on the launch, depending on weather changes I could have a pill set to just barley bring the front end up then the later in the day the air gets a lot better and the big wheelies start and I need to pill down on the break, what I was thinking if I switched to the m/t drag radial in similar size, I could keep the trans pill low, not pull a big wheelie and still cut good 60', ive heard radials are a lot less forgiving than slicks, the car is at 2650 pounds with a small block and 904, so witch one would be the best option???

I'm not sure where the center point of the car is, I had it scaled last year because it was going right on me, now that I think back on it it was a 51/49 set up with 51 on the front, its a 4 link car with afco single adjustables in the rear, up front is a spindle strut set up from the early 90's, no adjustment other than the coils, there are no markings on them for brand, the car leaves dead strait now sence the scaling, I mean I can chip the break down a lot and never worry about the wheelies but starts to leave like a turd, ive also been told to go higher on the pill so it doesn't flash the converter so hard, but the higher I go the higher and longer the front end goes up and out. the wheel base is only 96 or 98 long, at the end of the season last race the air was really good but had a 35 mph head wind, had a 3200 pill in the car and it was just coming up and touching the bars and back down nice, then as the wind picked up and air got better it was carrying the front end out and really high then coming down and bouncing though 2nd, then I chipped it down to 3100 and it didn't even pull the tires off the ground at all, and 60' fell off

If you have non adjustable front struts from the 90's, I would say you have spend some money on good shocks before anything. Second would be replacing the rear shocks with some double ajustables.

How much front end travel does it have? Tieing the nose down might help if it has a bunch of travel. Finding the instant center would be good too and adjust from there

Strap the front end down and or buy some better shocks.
As Monte said, a radial will only be worse.

Radials hook or they don't. And they DEAD hook, no tire slippage. So if it picks up the front when the slicks dead hook, it will do it EVERY time on radials.
The keep the car from picking the nose up on slicks is an easy concept. You need MORE wheelspeed to rotate the tires a little to keep them from dead hooking. So you need more power, less tire pressure, tighter settings on shocks, more front weight, different instant center......something How do you keep the front end down on a radial?

The front doesn't have a lot of travel, the car comes up extremely quick when it does, I think I'm going to move the bottom 4 link bar up one hole on the housing to move the center forward, the car originally had a big block in it before we bought it as a roller, I think moving the bottom bar up will be the cheapest and easiest thing to try first, still kinda interested in the drag radials though, we will see what it does with the slicks first

Where is the 4 link now and where will it be when you move it? You can't just think that LOOKS right or like it might help. You need to KNOW where it is and where it will be.
Also, a tube chassis, short wheelbase car with a loose strut is not a good plan
