Need a plan - component selection for restoring 68 340 that runs on 91 oct

I can tell you the combo I have.
.030 340 KB243 pistons, stock stroke, stock x heads, Lunati 703 cam, LD340 intake, 700 Holley carb.
73 Duster 4-speed 3.23 gears, 275-15 tires, stock manifolds with 2.5" duel exhaust.
Runs fine on hi-test pump gas.
But it is doggy just starting away in first gear, but pulls good after it is moving, and cruises nice.
I am used to just letting the clutch out, and the vehicle starts moving (jeeps trucks etc), the duster you have to give it a little gas.
I have deeper gears to put in it, will play with them at a later time, but the engine is what I expect out of it, a nice cruiser.
It ended up with static compression of 8.98:1, dynamic is 8.06:1 with 160 psi cranking compression.
I should put a little smaller cam in it to gain some torque back, but it is livable the way it is.
