Post your 10 second combo
You should definitely be running quicker than high 10s at 130 MPH. I'm running 10.20s at a best of 129... I see you had traction issues in the video. If that's the norm I would work on the chassis/tires before the gear change.
The big block stroker motor really doesn't need the low gears to get into it's power band since the power band is so dang wide :D I'll be honest with you, I made that same change, 3.73 to 4.11 with my 512BB and barely saw a .1 improvement. My chassis and motor are working in harmony. According to the calculators I really can't go any quicker with the MPH the I'm running.
If you haven't already played with the calculators here's a good link:

BTW, I see you race at 'da Grove. I was just there for a visit in August. That was my home track in the late '70s early '80s.
