Wake up a 1968 318...

I have a 1968 318 with (what the PO says is a) dang 1 barrel carb that has no choke and I want to wake it up. It's in a van and I am not really looking for any major performance upgrades, but I feel like the motor has a lot more potential without doing all too much to it.

Does anyone here have experience with this? Again, mostly looking for reliability and mileage rather than ton of power. SOME more power obviously, but nothing crazy by any means.

Would something like this work?

I had similar situation [ Powerwagon 886 ] ambulance pretty heavy and I installed a Isky
RV/TOWING camshaft and Old school Offy intake with Edelbrock 600 carb it really gave truck nice low end power from idle up to about 3800 rpm well worth the effort.
