    OK, thought I would test the waters on these forums again and see if someone might have a good explanation for my newest Cougar head cramp :( Just got a brand new 600 cfm Holley and installed it the other day and BAM cougar runs great.... finally! Idles right, revs right (nice and smooth) etc...
