LS firing order. don't use with a dual plane intake.. Make sure the headers are correct, too. Might see a little HP if all is right, but will definitely see better main bearing life and possibly timing chain wear.
BTW: One of the stories on why Ford did it on some HO 302 and all 351 W's was to stop breaking cranks and have less front main wear.
