finally made it to the track
Well guys i finally made it to the track. I was fairly impressed with my times. Tell me what you think. it was an 1/8 mile track since that is all that is around north Aabama. I ran a 7.77@ 92MPH with a 1.82 60' time

Your 60' look pretty good. I'm not sure about the 1/8. I never pay attention to my 1/8 because all the tracks around here are 1/4 mile.

I would say that is a very good time. I just went to the track and could get no traction. I was running 2.5-2.8 60' times, but I did get 104 mph. My 1/8 mile was around 85 so I would say that you would hit around 110 maybe in the quarter.

Outstanding... you're flying. Here's an equation developed by a fellow board member that I have found to be dead nuts on, at least in the high 13-low 14 second range.
1/4 mile ET = 1.7287*(1/8 ET) - 0.7392*(60' time)
If I punched the buttons right this equation predicts you'd be running 12.09 in the quarter. Elevens would be easy if you dropped your 60' times to a range in line with power you've already got (1.55-1.7).

You've got the LCA relocation brackets but didn't mention any other suspension mods or what tires you're running so here's a generic answer. You may already have much of this covered.
1. Replace TCI converter with a Vigilante or Yank. I know you're probably not going to like this suggestion but the fact is a stock L98 on drag radials radials can run bottom 1.8s in the 60' with one of these converters. This change alone should put you in the 1.6s if you've got the traction.
2. Run drag radials or sticky bias ply tires out back. Front runners that match your rear tires mounted on lightweight rims really help.
3. Temporarily disconnect the end-links of the front sway bar or remove it entirely (both mods are strip only).
4. Install an adjustable torque arm and set the pinion angle between -2 and -4 degrees. I have the Spohn unit and like it.
5. Install adjustable struts and shocks. Set the front struts on soft for best weight transfer and experiment with the settings out back.
6. Good tight posi (obviously)
7. Practice, practice, practice. You're launch technique will only get better with more seat time. Have someone watch your burn out just to confirm you're not dragging any water up to the line.
There's probably a lot more that could be done but that's a few things right off the top of my head.

I agree entirely with the converter suggestion. Mine only stalls to 2000 instead of 3000-3500 RPM. I am running M/T ET streets but they have just about had it. Mine friend pisses me off. He runs 1.5's on stock suspension and M/T et streets in an 89 Formula.
