This thread though short is an interesting read about the Fords.http://forums.corral.net/forums/5-0-5-8-engine-tech/1197196-best-firing-order-sbf.html
Some claimed the 351W got the revised firing order because it had front main bearing wear issues. Others claimed that the 5.0 HO got the 351W firing order only because they used a Torino cam. Another pointed out that Ford lightened the block after '78 and need the revised firing order. Anyway, any front bearing wear problem is an issue of main bearing web strength and Ford windsor engines, and not extrapolatable to other V8s brands like Chevy
. Other V8s can handle the old firing order
