Yes the fuel curve is the same for 305 vs. 350.
Injectors I believe are different but will work in the 350. Might be a good idea to check with the parts store on this, they aren't a big deal to change out. The Fuel pump, sensors and ecm are the same. You'll be able to swap the 305 w/350 without having to change a thing. Make sure your 350 comes with the balancer. Everything else will interchange.
We get alot of the older trucks (88+) that want the 305 swapped out with a crate 350, been done many times.
