How much ET drop for (10.9@125) car if going from 1.47 to a 1.39?

I am curious about your trap speed, seems a little high for the ET. Locking the converter? Or does the cam have a good top end charge?
On a pass I made with my auto car a few years ago, I ran 10.74@125.7 with only a 1.60 60'. On that run, if I had your 1.47, it could have been in the high 10.50's.

Tom, yeah i do like racing this car a lot, no trailer and what not. Though the next project will likely get trailered when it gets serious (haven't bought the roller yet but looking hard).
Al, thanks for the interest. Car was 3800-3850 raceweight with a 3800 converter, so that might account for the lazy ET? Did do 99mph in the 1/8th. I figure we loosen converter to 4200 and start trying hard for a 1.40 60. We lock the converter in middle of third gear otherwise it buzzes thru the traps 300+ higher.

A buddy just went 10.66@127, so I'm thinking I'll have to definitely lighten the car and make more power to run 127. He went 101 in the 1/8th and I've been just a bit shy of 100 MPH.
So 10.65@127 is my goal.

John you know that you can only get so much from a car. Then it takes a lot to get so little results. Keep playing with it, but I think it's going to take more than 90 lb weight reduction, 400 looser stall and E85. That may put you at 10.75. Got to get that 60' down. JMHO.
