Aluminium Flywheels

I know you are mostly talk'in small blocks here.
Just to add some to this to help clear some ideas.
4.25" stroke 440 18spline 833 in a 3100lb 69 dart 4.10 to 4.89 gear. have both.
90% drag 10% trip to the drive in.
What flywheel lb would you run? Mid rpm solid roller cam, med size port aluminum
head. There seems to be different trains of thought in this post so far. What
would you use with this combo?
Thank you all,
Rick
