I'll try to go through this in order:
- Beat your dial index if you can...
- you missed subtracting .6 for having a 360 C.I. The -.3 you did was for your block being a magnum.
- your 3800 stall is a -.7 deduction instead of -.4. You must have not scrolled down to the 2nd page of the box.
- This would make your dial index 11.90. If you did get the deduction for the 360, then you'd need a 12.50 because of the converter.
- You can make your run(s) anytime in 2018.
Hope this helps.... thanks. Let me know if I can add you to the list! :)
