converter?   ???

afaulk:
I have a home built chassis. Its 185", 4.30 gear, 1.69 low in trans, 33x10.5w, 370" Blown SBC, about 900 hp. 9", 5500 converter. We made a couple of test hits on the new chassis last fall and the car wanted to go right. This spring we made about 4 more test hits figuring out what it wanted. First I added 40 lbs to the nose (battery and fuel tank are up front also). Car was still going right at the hit. I raised the bar from 3" to 4.5" and added another 40 lbs to the nose. (the bar is about 66") the last three passes have been 4.90, and 4.80 with 1.09 sixty ft  and 4.75 with 1.08 sixty ft, leaving off idle and shifting at 6200. Oh and 7 psi in the slicks.      It sounds like your car is doing the same as mine did before adding the weight. Dont be afraid to add a weight bar. You've got to keep the front end down and you've got to get it up on the tire. Good luck! PS. Not sure how much faster I want to go...…..

The Dragster I have worked on and driven for years is a 185" mild steel fed. 565 bbc injected alky. We had to run 5 to 5.5 psi in the slicks with bar at about 2" to make it work and yes 33 x 10.5 m/t slicks. I am no pro but the higher pressures on a well prepped track killed us every time FWIW. 6200 converter also. It would 1.13 to 1.15 in 60'.

crider:
Ok. Seems like some good suggestions here to try. Weather permitting I'm going to try to take it back to the track Friday night and play around with the timing and air pressure. I think I might try a lower launch rpm at some point too. If this doesn't work, who is a good source for a weight bar for the front axle?

You could check with the guy that built your car if you're in need of a weight bar
