The negative battery cable is grounded to the battery tray and engine, close to the starter on the block. It's not a real great ground system but, its all you need if you can keep the battery tray connection clean.
I have a 2.3 quad 4 in my 95 z24 and a 2.4L in my 01 z24.

The Z24 engine is an overhead valve engine and the Z34 is an overhead cam engine. The Z34's engine is pretty tight in it's engine bay so if you were thinking of doing a "swap", Z34 engine will not fit in the Z24.
Every typical "V" style engine has a timing chain. the Chevy cavalier z24 has a 3.1 liter FI V6 engine. so yes it has a timing chain.
It is on the accumulator.
