I am concerned about the operating temp of my 428. I have a 4 core copper radiator with a electric puller fan (2300cfm). Temp will go up to 210 deg on a hot day city driving. I have changed to a 160 deg superstat thinking that would help. It will hold at 160 at 60mph on cool evening. front inlet is completely closed off air only comes in through radiator. 1st what is normal operation temp for a 428 in original '68' mustang and does this seem normal? if not any suggestions? Thanks for any help.
