I can tell you from using both setups, the layout of the tuning software for the megasquirt is much better than binary editor(moates).
One which stands out is the realtime spark and fuel tables. There is a dot that moves around the table, showing you which part of the map the engine is using.

ALWAYS choose the V over the P!!! Wait... what?

good sofar, waiting to see once you get her set up and knock down your 60ft. any idea what she has for torque ? hp #'s look decent enough. I think the big head theory will come in high in the revs vs some of the smaller head motors. geared right ( tranny & rear ) I think she could scream.
****, you're going to pick up some good power from where you're currently at. 330 at the wheel? That might be stretching what you're currently at a bit. I'm going from judgment not math here. I know what my old car ran with 311(dyno)-320 rwhp (depending on what that cold-air intake picked up). It went 112.9 mph with 3150 lbs race weight and 4.10 gears. Are you making more power than I did and only going 110? Probably not. Same power with the extra weight? Sounds pretty close. I'd definitely say you're running at least 300rwhp, which to me has already proven your point. FWIW, I went 110mph the first time at the track with the AFR165/FTI cam/ported cobra intake combo. I went 12.9 though
Just curious, what was the 60' when you went 113? That's a damn strong trap speed. Also, what wheels/tires did you have on it?
Ha, that's cool. I may do MS at some point, but I just went through a lot of trouble and $$$ on this car's MAF setup, so it's hard to justify pulling it all and selling it.
Torque...
Feels like any other H/C/I 5.0 that I've been in. Has no problem getting sideways during a turn or doing smoky burnouts. 
It'll get dyno'ed... Someday.

15" weld draglite wheels, 26" Micky thompson ET Streets (old tubed non-radials) with skinnies up front, 4 cylinder springs up front too, with a removed sway, rear suspension stock with an airbag in rear right. ET was an 11.96
That's your mark, and it's definitely reachable given your track performance already. Now show me what's up with this big head, small cam stuff!
Edit: Oh, and the car was a little lighter than yours (maybe I already said that)... Weighed 2976 lbs on 1/4 tank. Lightening stuff: Aluminum heads (obviously), removed A/C, dog-bone, rear tire/jack, 1/4 tank of fuel, sway bar removed. That's about all. Now that you've got me thinking about it, I always wanted/wondered how it would run with a 125-150 shot, & 3.73 gears. Back then, I was planning on going mid 10s with traps in the mid-high 120s. Car was the cleanest stock-looking fox. Even the ash-tray door and the center console worked perfectly. That old car was probably my favorite setup because it was so underestimated (you'll see). I used to outrun blown foxes, LS1s with light bolt-ons, BPU Supras, etc... I got accused of everything from running nitrous to running a stroked 351. They just couldn't believe it was a 302 with a stock bottom-end. That kind of non-belief was the best possible compliment they could have given me. I enjoyed that car so much that I've often thought about getting another car and doing it over again. Maybe next time I'll be doing it with 205cc heads, though

AH, see, that really makes me want to pick up a set of stickies and skinnies. I think that's something I'm going to have to do this winter. If I could tag 11s, I'd be tickled pink.
Alright, I'm going to pick your brain a little more. This was an Ed Curtis cam with AFR 165s and a ported Cobra?
1. What was the compression ratio?
2. Did you have long tubes?
3. Was that power shifting?
4. Mind sharing the cam specs?
I originally had intentions of setting this car up for auto-x (thus the Cobra brakes), but after the car's performance at the drag strip last week, I think my focus is going to be drag, haha. I've drag raced the car before, but it was never fast enough to get really excited about it. Used to be a ~14.3 car with the old E6 heads.
3.73. I realize I could probably benefit from going bigger, but I really like how the car drives on the street/highway, so I don;t want to ruin that.
If I had a 6 speed with a nice 5th and 6th overdrive, I would have no problems with running a bigger gear. Right now, at 70, I'm turning 2300, and I don't care to go any higher. It's mostly highway to get to the drag strip for me.
Yes. Ed ported the lower cobra for me. Cam was 224/228, and 111 LSA, lift was in the mid 500s (.555/.560 if memory serves).
Stock pistons with heads milled .024, and .039" HGs. Think it worked out to very near 10:1.
Yes. BBK 1 5/8" headers. I ground out the weld where the primaries mate to the exhaust port and opened up the collector as much as I could without causing a leak.
Always
Guess I anticipated that one already

Consider calling Baer. I'm pretty sure my Track kit is almost identical to cobra brake setups, at least in terms of calipers. I called them and went from 13" rotors in back with appropriate brackets for the calipers to 11" rotors. At least talking to a tech there will give you some insight on the options available to you.
Oh, and 14.3 ain't bad. My best with the E7s was a 14.2@98 (Mods = K&N filter, 14* timing, glass-pack mufflers)

NP Nik. I personally think you've got plenty more potential in that car than I had in mine, especially when you start extending the limiter. I want to see your numbers blow mine out of the water. 11.5s anyone?
Oh... to clarify, in case you go to the trouble of doing the math on the compression, I had the pedestal mount AFRs... Pretty sure they started at 60cc combustion chambers. Not 100% sure, but I think .024 took 4cc off of the chamber size to 56cc.

And.... I couldn't help myself: Whitby Motorcars great calculator there with all the stock 302W info already listed for reference. I'm gonna have to save that page to my computer when I get back to it.
Anyway, According to it, my static CR was 9.73

Cool calculator. According to that, my CR is around 9.8-10:1, which is about what I had figured it to be before. I was originally aiming for 9.5, but my pistons measured between .005-.010" above deck, so my CR ended up being higher than I planned.
