I agree. Ran my 408 100 miles one way. No issues with oil too hot, but that depends on what is considered too hot. Block was filled just above soft plugs. Oil never got over 250* and i aways run 20/50 premium oil. I use Amsoil most of time with Brad Penn racing oil when moneys tight. No oil cooler on that one, but water temp was 200*-210* most of the time using electric pump and fan. Now have a 511 filled within 3" of the deck.Water temp was 185-195* most of the time past summer using mech pump and fan. Gonna try same without a cooler, but will be using Amsoil as 250* does not hurt it and Amsoil claims its good to 300*, will see.
