The 300zx would win but how can you compare an 87' to to a 98' or even antying like that? An 87-89 will whoop up on a 90-93(other then 93 cobra). If you don't believe get two bonestock cars on the opposing sides and race. Let me know the results.
And then, comparing a fox body 5.0 to an SN 5.0, how dare you? And what's worse...alas, a fox-body 5.0 to a stock 96-98 4.6? The 1/4 mile times will be close to a 1/2 second difference. Most drivers would be lucky to hit high 14's with a stock 94-98.
