By all means, yes it will
Yes.
Which engine?
The 1995 Z28 camaro has a v8 engine in it. That engine is a ctually a steel version of the corvette engine. Since there are 1995 camaros with v8 engines in them, you can probably fit a v8 into your car.
There is no difference. There the same.
The engine.
yes it can
it costs 10 dollars
yes, may require wire harness and computer from sunfire. Consider removing motor mounts from sunfire as well.
if it is a 3.8 then it has about 220 at 5200 rpms (3.8 is the v6 1995-2002 i think) OR if it is a 3.4 it has about 175 at 5000 rpms. (3.4 is the v6 1994 camaro)
15.5 gallons
Would need engine size to answer this.
