deciding on a cam
the motor and trans are now lined up correctly and bolted together, without changing the motor mounts.
the block does have a bunch of random numbers(probably a vin) and after them it has 318 engraved in it

I just found something interesting, guys http://www.cranecams.com/164-165.pdf
The more interesting part, aside from there actually being three cam options for our TBI motors is the description of the third cam. " . . . also mild turbocharged, computer upgrades required . . ."
WHAT!?!?!?! Where is this turbocharged, modified-factory computer TBI 318 I so unrealistically desire?!?!

You can purchase and run a hopped up cam in our trucks. The engine just can't utilize what the cams offer without replacing the injection system and the computer control system. As I said: You can modify our engines or anything else if you have the budget. Doesn't it always come down to the money.
I don't know where all you guys live, but here in the county I live in in New Mexico, it just HAPPENS to be the ONLY county that requires SMOG checks every two years. SO, as a result, I can't do a manifold carb swap for my TBI. However, I think there is an alternative. Edlebrock makes a sweet injection system for these trucks (at least I seem to remember seeing one before I got this Dodge) but it is kind of expensive. It is almost infinitely adjustable as it comes with it's own computer. As well, a well tuned carb can be very good at throttle response and emissions. If I was in the OPs place and allowed to do a carby intake swap that is what I would do WITH a hot rod cam, and some roller rockers, and even maybe up the compression a tad whilst at it. Surely this would be way over his budget!
As well, I have a 1974 Chevy 4x2 4 speed, 3 fitty, posi, long bed 3/4 ton that already runs well but since is is older than the smog requirements, and you can buy 500hp worth of hop up parts off of craigslist for 500 dolars for a 350, I might get into hot rodding that truck.

I think a new cam will help a little bit, but with stock PCM the full potential of the cam won't be realized. I don't know anything about the throttle body injection PCMs, do they use a Intake Air Temp sensor? If so, you can move the sensor upstream from the engine a bit, so that the sensor sees cooler air, this will richen up the Air Fuel mixture and advance spark some.
I am running a stroked 360 in my 1995 ZJ with the stock 318 OBD-I PCM. I did the Intake Air Temp sensor relocate like I described above, along with a fuel rail with the fuel pressure regulator mounted on the fuel rail and bigger fuel injectors. It runs, a little rich under WOT, but works good enough for now.
