I’m going 132 mph at ~7000 rpm with 4.56’s and a 29” tall tire.
Whats your tire height?
If they nail the efficiency at the top end you can have your cake and eat it too.
The same converter before we tightened it up a hair was going 7600 at 130, but was hitting harder off the line. The car was trying to turn over backward with more power from the 4” stroke.

It's time to feed this beast! A new cam,TSP rockers, and .685 BTR springs on the way for the 447. Huge thanks to Darth for help with the new specs!

Are you going to re-dyno?
Once you have a dyno sheet you share it with FTI and they can match your converter.
They can definitely get better on efficiency which would let you keep your 4.30’s or maybe even go to 4.56’s someday. Flashing just past torque peak is what you want which definitely sounds like it’ll be around 6000 rpm especially with a bigger cam.
You're close to transforming this thing. Exciting man!

Well just got home from the dragstrip and I've made some progress. My best pass on the transbrake has been 10.11 and the best footbrake pass was 10.22. I made one small change this week and it paid dividends, tonight I ran the footbrake class and she went 10.12 a full 1/10 better and did it in 98% humidity. I pulled a play from the old timers handbook and put on a pair of 18" header extensions......lol. Had I been able to run trans brake she would have been in the 10.0's. I also won 9 straight rounds and brought home a 6' trophy and some cash. Can't wait to get the new cam in and get it re-stalled
