Most people recommend running a 195 to help the fuel economy.
I run a 195 in mine, works great as long as the rest of the system is in good shape and has a 50/50 mix of coolant. No troubles overheating or anything.

i think most FE's came stock with a 160, id reccomend a 195, i got mine through jegs for $8.99, but most part stores should have one in stock, i dont know how much it helps gas mileage, but with gas at $2.00, i do all i can to get the best out of it.

The higher the temp the better the gas mileage. That is why automakers keep pushing it higher. Anything under 180 and you damage your engine. Engine wear rates double for every 10F lower than 180. So a 160 stat will wear your engine 4 miles for every mile you drive. Computerized engine controls, better cooling system design, and higher engine temps are part of the reason we are seeing longer engine life in the newer vehicles. My 390 had a 180F stat.
