Need advice/opinions on my scenario

Ok, heres the scenario. Hopefully a few people can help shed some light here. I currently run a 11.7 @ 124mph at the drags. I have 26 inch MT et streets, I run 4.10's, and use a tremec 5 spd. Right now I run out of gear and bounce the rev limiter through the last 150-200 feet prior to the traps. Last time I went to race, I snapped an axle. So, I made a phone call to Moser.
I plan on running 35 spline axles, with a spool and c-clip eliminators. Also I plan on running 3.55's
Does anyone maybe have a feel for what I should expect? Will my speed go up or down? What about my ET? I'm curious. Normally speed would decrease ET would increase - right? But in my situation where with the 4.10's I was not accelerating anymore - What tdo you think?

Thanks for the Help/suggestions

I cant go to a taller slick. You actually think my MPH will go down... I am not sure i completely buy into that just because with the 4.10's I am no longer accelerating the last couple hundread feet due to bouncing the rev limiter that entire time. Also i was thinking that with the 3.55's I would be in the power band of the motor longer, versus at redline with 4.10's...
