I am running a 1973 360 in a 1953 Ford F-100 panel. Has full shroud around radiator with a 3600 cfm elect. fan. Running stock '53 ford radiator.

Engine wants to run a little on the warm side 205 to 210. Not awful, but I'd prefer 190-195. I have the relay on the elect. fan set to kick on at 185.

Noticed today it has the original 7 lb radiator cap. I think the 360 ran a 16 lb cap.
Think changing the cap would help cool me down a little??
Should I go to 16 lb or something in between?
