Heat with a blown motor

I read with interest the article in the August 07 issue about "Ham-mered" from Arizona and the constant overheating they experienced with the 350 CU blown engine in a 36 Ford. They eventually replaced it with a naturally aspirated ZZ4 crate motor and the problem went away.

I just did the opposite. I converted my naturally aspirated 1930 Ford that has a 383 CU Chevy to the same but with a Wieand 177 huffer. I am retaining its street manners (I hope.)

I am curios why the blower itself got the blame for the overheating. I have yet to fire my blower conversion, but now that I have read their article I am concerned that I may experience the same.

I don't know why just adding a blower would change the heat the motor creates at normal street power settings. Can anyone explain this to me? Should I be concerned?

Blower motors can be driven daily without any issues. Of course this is within reason. You are not going to make a top fuel engine drivable on the street.
