Critique my planned combo

I would use the tallest tire that will fit under that car, maybe a 29 or 30inches and add more gear to make up for it. With a 10pt cage and frame connectors your car is going to be very stiff, making you rely on your suspension. If its in your budget forget about the super stock springs and do an adjustable 4-link or at the very least by a set calvert springs and bars. They do work. I would look into getting weight off the front of the car, fiberglass hood and bumper. That will help weight transfer especially on stock front susension.

Firebird is a great track... Racing in the spring and fall and into the evening hours the track does get cold making hooking up in the later rounds very difficult. Its frustrating to spin a way your win!!

Keep in mind to the corrected altitude is almost never at 2700ft, maybe during the halloween classic. During the summer it easily hits 5-6 thousand feet. You can expect to slow down during the summer...

Your ETs can swing 2-4 tenths during the day out there, Get a weather station. I have a spare if your interested. Once the sun drops behind the stands in the evening everything changes, the track temp and corrected altitude.

Spend some money on valvetrain, springs, locks and retainers. Isky Super 7 "7degree" are nice highend pieces that you can rely on.

Don't waist your money on a shelf converter. Get a dyno sheet, car weight and order a custom built unit. Theres can be an easy 1/2 second to a full second on the right converter and it will more consistent. They can build it to handle the transbrake, weight of your car, A1 in vancouver,wa is great and they know mopars. Look into a mechanical diode sprag.

I would also consider an electric water pump, electric fans and a nice alum. radiator. That will allow you to cool the car between rounds.

A vacuum pump is another way to pickup another easy 2 tenths!!

You didn't metion exhaust but an open X-pipe after your headers picked me up another 3/4 of tenth.
