Yes the digital dash will work as normal . The only thing they share is the Tach wire off of the HEI . But putting a Vacuum lockup switch or similar for the torque convertor is necessary because the car will randomly lock it .

opening up the intake flow and the exhaust flow, getting the fuel pressure needed with stock cam and head could get you to 280hp.
most of this is labor. lots of grinding. new gaskets. after that its going to to start to costing money. new heads would be next

If you're are a broke high school kid you can't afford a 40 year old corvette unless it's inherited. You will like have plenty of worn parts to replace. It's old enough auto shop instructors may not be much help.
With that said before you buy car, have a pre-purchase inspection done and see what kind of shape it's in and what needs fixed for safe operation. If the Crossfire is operating correctly and there is no drivability issues leave it alone. They're easier to screw up than to correct. Stock C4s as a rule aren't rockets they are corner carvers , on a windy road they can embarrass cars with more horsepower. If in the future you want a rocket save you money for a ls swap.
