i have a 360/380 crate engine and have been using autolights 3924 and 0ne range colder 3923. if you try the fram autolight web sight they do give a very good break down on uses including crate engine requirments.thats where i got my answere to the same question.
plus my local auto part stores seem to have them on sale often enough at 49 cents each
