Are these cars slow to warm up?

I have two 3/5s,
Both have 195* thermostats,
the 99 takes 8+ miles for the engine to warm up to operating temp. in the cold (sub 45*) weather,
the 93 takes 2-3 miles to warm up on the same day.
Why?
Your SWAG is as good as mine.
I've checked all that I can think of.
Same coolant,
the 99 radiator is slightly larger than the 93,
same thermostat,
same fan,
same engine, yes, both engines are late model,
one Xfi cam (93)
one standard cam (99)
The 93 fan actually comes on earlier (205*) than the 99 (212*) measured at radiator neck with digital thermometer. I once read that there are 2 fan switches available for the car, so that may answer that issue,
Same oil,
Same oil filter,
Same trans oil,
93 has a smaller grill block than the 99, so that is counter to the my personal logic,

and the heater in the 99 is not nearly as hot as the 93, but that is a non-issue here.

When you figure yours out, let me know, maybe I overlooked something.
i had a 93 that would cook you out of it until it rusted out. now i have a 95 that has pathetic heat. i have changed tstats, heater core, water pump, engine, hoses, and even reweatherstripped the heater core box and air doors.

let me know too.

Oh yeah,
I forgot that I had done that.
That helped a little.

Replaced tstat with new 195 one. Still takes forever to warm up.
