Advice on improving my 60 foot times?
Have a look at this video...
http://s97997631.onlinehome.us/temp/427bird/launch.wmv
This is launching off the transbrake running NA... the track prep was not great, however I still think there is room for improvement on how the car leaves...
The car is pretty light at 3300lbs RW... has a full drag suspension with all the good parts... 1.76 glide, converter is setup to handle a 300HP shot but still works OK on the motor... 3.73 gear... MT 28x10.5 stiff sidewall slick. QA1's are set to 1 up front, 5 out back and tire pressure is 11psi cold (no tubes).
Best NA 60 foot is a 1.50, best spray 60 foot is 1.39 with a 200HP shot when I had my 4.10's... best 60 foot with the 200HP shot and 3.73's is 1.43 (the same weekend as the 1.50 NA pass, I only got 1 spray pass in...).
Here's an in car video of the 1.43 pass... as you can see from the steering correction on the launch, there is some wheelspin...

What suggestions would you guys make? I plan on getting a little more agressive with the tuneup... I guess it's possible the car might just need a little more power to help it get moving?!?

Can you put a trans break in it? For an all out drag suspension you should have a better 60ft. Maybe your converter needs to be flashed and footbreaked? Not sure I only know a little about auto's but my car is a stick with stock shocks and springs and I cut low 1.5 60ft's NA and in the 1.47 's on spray and my tires weren't screwed in so my 60ft's should get better next outing cause they were turning in the rim. I say it's the converter

I have never seen a converter that will work with a 300 shot and than work N/A.
My '70 1/2 only had a 175 shot and I had to have 2 converters. Just my opinion.
I can't see the video, so I'm just going on my experiance. Another vote for looser converter.

We'll see what happens when I put more spray to her !
