Cam and carb selections

I would Leave the Factory cam in there
After that, any carb, any intake, any logs but free-flowing exhaust.
After that, a 2600/2800 stall TC, and those 3.08s should be good, as would the Mopar ratios of 2.94 or less.
Then fix the sick factory timings.
If you really want a cam; one size up on the .050, but with faster ramps and solid lifters.

I ran this recipe,(with a 2800TC) with several different transmissions and with several different rear gears, for every winter from 2001 to 2004 or 2005; except I ran the Thermoquad and TTI headers with full-length 3" dual exhaust. That exhaust belonged to my 367, summer engine, so I just left it in there.
One winter I ran it with a Mopar 3+1 overdrive and a GVod behind that, and IIRC, with 3.23 rear gears. This gave me a double-overdrive and 65=1400rpm. I live on the prairies, so on the flat the 318LA had no problem pulling that.
The point is this, endow your engine with plenty of cylinder pressure, by keeping the current cam, or going to a solid-lifter design, and keep the rpm down, and give it about 50 or more degrees of cruise timing, and it will reward you with lots of mpg, while the 2600/2800TC will give you adequate off-the-line drive-away, especially with a 2800 and the TQ.

IMO a bigger hydraulic-lifter cam, will lower your cylinder pressure across the board, and with 3.08s you will not see a performance increase until say 35mph in first gear. Your cruise rpm with the 3.08s will be close to 65=2600rpm with 27" tires, so there is no problem with going to at least a 2600stall.
But with 3.08s your starter gear of 3.08 x2.45(A904) is just 7.55, so IMO, the 2800 will be a better choice for getting off the line.
The 3.08s will get you a nice passing gear of 60=3700 in Second, close to and just under the stock-cam power-peak. If it can breath, it will "fly". By 75 it will be up to ~4500ish and rapidly falling off the cam,so just about right.

If you had access to an A998, with ratios of 2.45-1.45-1.00, WITH a lock-up TC, I would recommend a 2800 TC, for extra hill-climbing power. Instead of pulling 55@at ~2300 (in Drive) with a stock-stall TC, the 2800 will come out of loc-up, and spool up another 500 rpm ,and find maybe 20/25 or more horsepower up there. Meaning, you don't have to downshift as often, if at all. I ran this combo with 3.55s and it was a lotta fun. But it wasn't that great on gas cuz,65 was almost 2800, in loc-up. Yes with stock hydro cam.

Good luck with whatever you decide, but my best advice is to NOT install a cam with a later-closing intake valve.
