Your gas engine should be fine with a regular tuneup. Diesels sometimes need block heaters but certainly not in Texas.
My 99 5.7 did come with a blockheater but thats because it was a new hampshire truck where it can get extremely cold for long periods.
Living right on Lake Michigan makes for extremely cold and windy winters. I can see the lake from my house and my truck feels all the pain it dishes out all winter. That block heater was a life saver when it was below zero for several days in a row last winter. In Texas I would say it would be overkill.
