Quick question - where does your neeedle normally position on the temperature gauge under hard running? Thanks

This can very and depends on alot of factors. Not really a good question, sorry.

If an autocross somewhat qualifies as hard running, I have never seen my temperature needle touch the 10 o'clock position (with ambient outside temps of 45 C). I have a 3.6 T with an extra oil cooler. Usually it sticks around 9 o'clock even in fast street driving.

Under no circumstances should you let the temp go above the halfway mark on the gauge(210F). That's a Bruce Anderson rule as I remember. My owners manual says not to let it go above 300F(I think that's the second highest mark on the gauge) but thats just wayyyy too hot. Mine never gets close to 210F unless I've been running flat out on the highway for an hour. My only oil-cooling mod is the B&B fenderwell cooler.

Ol Bruce says 180-210 F is normal. From there it goes:

220 F: Warm
230 F: Hot
240 F: Too dam hot

My '87 (346 rwhp) runs at 210 when ambient temps are about 90 F and I have a fan assisted fender cooler (kicks in at 240 F I think, but mine has never come on) and a air dam mount oil cooler. At the track, it may reach 220 F or so.

My car is a European model. So no actual temperature marks on the dial just a lower mark at 8, a higher mark at 10 and red at 11o'clock. Under hard running, mine sits at 9.
Hard running means prolonged fast road reving into 5500-6000rpm.

your gauge sounds like mine w/o numbers on the visable gauge face. look really carefully where the gauge face meets the outer rim of the gauge/bezel. the 8 o'clock position should be marked 90oC, 10 o'clock at 120oC and start of the red rone 150oC.

if it sits at 9, that's half way between the 90oC and 120oC marks. 110oC is equal to 230oF. Bruce calls that HOT>>>

Here's a pic of my old one before I swapped out to a numerical gauge. You can see the marks in Celsius. The very small line at the topis 212* I believe.

Celsius to Fahrenheit conversion: C x 1.8 + 32 = F
