IMHO you do not need a new intake or carb, or 1-3/4 headers . what you are doing with the little cam is not too bad.

But to get to 11's you will need more power. and there is something killing the top end by at least 2.5 MPH.

I had a 130GPH mech pump yet that turned out to be my problem. switched to a 72GPH rated electric (7psi), big diffeence. no more top end fuel starvation.
I would look at the fuel system, exhaust system and cylinder heads for power.
what is the part number stamped on the front of your dart heads?
Again if non platinum series, they need work.
If you want a cam, the COmp XE284H-10 cam does work well. The crane solid will work better.
Why did you take the 4.10's out? re converter slippage %: recalc using the true effective loaded rolling radius of the MT tires. (measure from the ground to the axle C/L) you will find the tires are shorter than 28".
when I estimate your loaded tire radius I get 7% slipage 5900 rpm 108MPH 27" effect diameter.

If flowmaster mufflers they always cost performance. Sometimes a lot of perf. You'd be amazed.
uncap with collector extensions and test.
The converter efficietrnce improves the further away from the stall speed you get (RPM), thru the traps.
Your trap rpm should be 6600+ rpm. You need to get your 60ft down 1.60 sec.

The weight seems pretty light. I'd rescale it. Everybody is repuatable until they get caught.
Because based on 3200#'s and 108 MPH you are making 375-380hp
based on 110.5 mph (87 MPH in the 1/8th) you are making 392 HP. This should be your trap speed now, not 108.
You need to add/find 50hp (after finding the power killer) and improve the launch to get it in the 11's.
