Hard starting after sitting for 5 months

I started the Dart yesterday, but it took a lonnnnggggg time to start. Wondering if the older 93 octane gas contributed to the difficulty. Here's the details....

Sitting in garage with temps going from 30 degrees to 60 degrees for the past 5 months
Holley HP 750 (no choke) (I may switch to an 870 with a choke later this year)
Fuel pressure about 6.5 when starting
Pretty radical 408 with 10.6 compression around .614 lift and 256 @ .050.
Fully charged battery
Complete Mallory ignition and Hyfire
Garage is dry and not damp
No sweating on the plug wires
Temperature when I tried it about 55 degrees

After finally starting I let it warm up for about 15 minutes to get up to temp and fully charge the battery. Shut off and started immediately, just like normal.

The fuel in the cell is getting pretty low, so I am going to put 5 gallons of new 93 in it and run it a while today. I am in the middle of body work, so it is sans bumpers and lights and I cannot drive it for a few months.

Thanks for your input!!
