Adding a Fan Shroud

Did you have heating issues before you made your shroud or did you build a shroud right away and dont know how it ran without it? If it was after you had cooling issues how much difference in temps did the shroud make? Does your temps fluctuate when your in traffic now with the shroud on?
What engine are you running and has it been bored or modified?
Thanks Rod

My build is a 273 out .040 with a Commando++ type build. I had the stock radiator recored to a 4 row X 7/16" configuration but during my cam break-in and watching the temperature gauge I knew right away I needed a fan shroud. I just measured everything up and fabricated my own using some of the advice on the issue found here on the forums. I did change from the stock 4 blade fan to a five blade clutch fan to help things out. For me the keys were standing the shroud box off the radiator at least 2" and giving the fan/shroud clearance the proper distance. I had no plans so I knocked out a drawing on CAD and went from there. The result keeps my car motor nice and cool in any ambient temperature. I could help it more by separating the transmission cooling from the radiator but it was not necessary in my case. Below are a couple photos.
