Another question I have is why no windage tray in the 5.7, but have one in the 6.1? I was looking on the Arrington Performance page and notice that they do make one, made by Milodon, but it only works with their oil pan, oil pick up, dip stick, bolts gasket, and comes to about $620.00 (the windage tray itself is only $74.00 and you also need headers to clear their dip stick???). They are claiming a 25hp increase. So why hasnt anyone else made one for a stock 5.7, seems like it would be fairly simple to fabricate. Even if you only made an additional 10-15hp it would be worth the $70.00. If it was added to the 6.1 then it shouldnt be that hard to add it to the 5.7, or am I missing something?
