That sounds the same as mine. Take it on a long slow, traffic jammed drive and see where the temps sit.
Make sure the fan comes on around 100 degrees and the oil temp stays below about 110. Also, question the owner regarding oil consumption. These engines have been known to consume a lot of oil. Roush states that they consider a quart every 500-700 miles as acceptable. You may or may not agree.

Thanks JHV, yes was in quite a lot of traffic and that's when it climbed to around 100c...outside temps were 12 celcius.

Thanks for the oil temp info, forgot about that, not used to oil temp gauge.

Yes, I have done lots of reading on these engines...read some things that scared me but I think I have an eye of what to look for. Car just had 9k worth of tuning to get efi working...it ran very well. Latest owner only put 300 miles on it but said it did not burn any.

Cold idle was 1200 rpm
Warm idle after sitting in some traffic got done to around 1000. She idled very well.

I will watch for the fans to kick on...how the hell do you know they are on? I doubt if you would be able to hear them....

What is the high engine temp to watch out for?

Car really liked to stay in higher gears in town....1800 to 2000 rpm or she liked to lunge a bit. I was very impressed with how she ran but didn't put her thru many paces.

We put it up on hoist and she looked great except for a slight oil leak where the braided lines tine into the sump/block...we have yet to check that out, hope its not nasty.

Car is 2100's SPF
Thanks for the help...I have read all the threads here and maybe asking a few newb questions....my mechanic will be seeing it for the first time this coming week....
