My mother just backed out on putting the 180 therm. in my car (she took it into the shop) because the guy at the shop told her that the computer was programmed to run the engine at 195 degrees and if you put a 180 therm. in it it would change a lot of things and it would not be good. So my question is two fold, 1. is there any truth to this?? and 2. if not can you try and write up a convincing argument why the guy at the shop is wrong?? thanks in advance

Yes, the mechanic AND the Father in this instance are wrong. Why? Simply because we have more experience with this system than they do. Nobody is stupid here, they just don't know why it'* an improvement. You have a collective experience level on this forum of several hundred years with the H body GM cars.
You will NOT see a decrease in fuel efficiency, but rather a possible slight increase.
You will NOT see a full 15° difference in operating temps. It'll only drop the average by 5-10 at the most.
You WILL see a slight improvement in performance and throttle response (hardly noticeable, but remember how your car always seems to have more power on a cold day?)
You will NOT cause emissions problems. If the Grand Prix'* in California can get away with this and still pass the strictest emmissions standards in the country, there'* no issue.
You ARE more likely to crack the upper intake on an L27 or L36 if you don't do this.
Don't bust your *** trying to convince someone to do this if they resist it. Wait for them to crack the upper intake, then tell them "I told you so!". The more you argue with someone, the more resistant to change they become. It'* a human trait.

I will have to agree with Will ( That ol Alchy I.V. injecting crazy plick
) don't argue wtih mom then... simply just go out and do it yourself.. it takes less than half hour, and cost less then 20 bucks ( including the Thermostat housing gasket, which you may have to get from the Pontiac Parts department ). No one will be the wiser. If it really was that bad of a mod.. then a lot of us would've already been argueing over it. As Rat has also once stated.. GM will ALWAYS want you to use the EXACT OEM parts.. so in turn, would you use the standard OEM exhaust system if you had to replace it? Most of us with 180 T-stat and tranny cooler don't really seem to run into the notorious problem of cracked head gasket ( providin the coolant system is working properly (i.e. no blockage ) Hector said I think ).. which also makes sense.

I can tell you that there was no loss of mileage in my Ranger when I did it.......and so far none I can see in the Bonnie either.
My temp guage reads approx 8-10 degrees cooler than it did.
Warms up to temp just as fast
All your doing is protecting your engine and components from heat.....and everything is better if it is a little cooler..........
Long term heat is detrimental to anything and contrary to popular belief........
Engineers aren't always right in everything they design into cars.
But.......I sure wouldn't tell you to fight with mom about it......that'* a decision you have to make on your own
Just like we all did.
Good luck
