According to Champion spark plug applications chart, the correct gap for 1995 Chevy Tahoe 350 engine is .035

Yes
no
No, not even close. Pontiac 350 intakes will interchange with 1965-1979 Pontiac 389,400,421,428,455 intakes. Most all aftermarket Pontiac V8 intakes are designed for the 1965 up bolt pattern. 350 Chevy is part of the small block Chevy engine family, and virtually nothing interchanges with a Pontiac V8.
It should be a 5.7L 350

The engine block coolant drain plug on a 350 Chevy Tahoe is above the oil pan, mid engine on driver's side
Chevy did not have a 350 in 2001 engine options were 5.3, 6.0. or big block
Which 350?? Chevy or Pontiac? A Pontiac engine will drop right in. A Chevy takes a lot more work.
