Fitech install update

[First c10]

My sons truck has a 355 with Vortec heads and a nice cam. His truck runs around 180 degrees all the time since I got the shroud installed. It does have a 180 degree thermostat and an aluminum radiator that was in the truck when we got it. I also put a newer serpentine belt kit I bought from a board member with a new belt and water pump. It currently has a Holley 650 Dbl pumper with manual choke which he doesn't have to use yet as it hasn't got below 60 degrees outside yet this year. It is running a little rich so not sure if that has anything to do with the way it starts. i do have a HEI Summit dizzy I bought for like 90$. When I installed the motor I added a vent line back to the sender so I can attached the vent from the FCC.
I am not sure what the time is set at as I had a friend do it when I was at work.
