1996 Chevrolet Camaro z28 Camaro

On saturday I swapped the spark plugs and wires it was about that time. Once I swapped them I cranked it and drove it around the car worked fine. On onday as I headed to work I noticed the steering whell was hard so I turned it to the left to see if it would loosen up and as I did so the car shut off and the steering wheel went back to normal. As I tried to turn it back on it turned on after the 3rd crank. The car continued to work fine. Later that day coming back home on 4th gear the car backfired and shut off the steering got hard again. I was able to park it, but as I tried to crank it the car would give effort to turn on but it would stumble and the clutch would grind and feel shakey as it was throwing white smoke from inside the intake manifold and coming out the throttle body. The car did not turn on anymore but would give effort to try and turn on but all you hear is it stumble, clutch grind and shake and white smoke from intake manifold. Everything on the outside looks well relating to hoses wires etc.
