He gave me a written estimate for @ $750. It didn't itemize, so thermostat and oil change would probably add. I want to put in the drilled 180 as soon as it goes off warranty anyway. "

Why are you contenplating a drilled 180 thermostat? Your car isn't supercharged. A regular 180 without drilling should be more than adequate. If you drill, you run the possibiliity of not heating up enough.

I've got a drilled 180 and it sure seems fine to me. My aeroforce has me sitting at 179-180 at cruise...
It obviously takes longer to warm up, but I don't think 5-7 minutes is crazy. It should be easier to bleed any air out of the system with holes at the 6 and 12 position I would think.

It did it later last winter. If the heat up is an issue in the coming season, i'll drop in a plain 180.

Why drop in a balanced thermostat and be done with it? Yes I realize that drilling your own is moe economical but a balanced thermostat has other benefits additionally, esp for you heavy footed sc guys and gals.

L36'*, just like L67'*, like being colder. Mine ran significantly better when it was colder (engine temps not air temps) then it did when it was warm. Going from a stock 195* tstat to a 180* tstat I noticed a good difference. Drilling the 180 would only help that much more. I really don't see a problem with it. Its not completely necessary, but neither is a colder thermostat at all.
