Also, if the trans has the fifth gear overdrive .64 ratio, make sure the engine is in its happy zone at your favorite cruising speed, Otherwise, fifth gear may be useless to you.
And the water temp should never go above 100 degrees. The SPF radiator and twin fans are very efficient at cooling these cars. The fans come on just below 100 degrees and the temp will drop immediately. Even sitting in traffic on a hot day.

JHV, just to be clear your comment was addressed to me and the IR engine correct? The car has Tremec 3550 5 speed with the dana 3.73 rear end.
Thanks
