What ET should my Duster be running?

Still haven't had the chance to get the Duster back out. Bloody house reno's have gotten in the way and working on the Polara.
Have sorted dizzy problem and will have no issue getting timing into it now and have re-set the rear as well. Hopefully when I get the chance to get it back out there I can break into the 12's.
Thanks for following up. Lots of folks never do.
The timing fix is easy and essential.
Is your compression really 9.2? Was it checked? Even if it is, that's not much.
Don't give in to N2o or more mods until you get what you have right.
