Default 660 Holley #4224 opinion?
Ok,

I know I have railed in the past against overcarburation and that in particular 600 cfm vacuum secondary are a big compromise at best and at worst. Well you know.

So I have lived with my Holley 9660 450 mechanical secondary carbs on my 427 and am well, not impressed. Yes they run well and seem perfectly happy but I can tell there is more to be had.

Shelby is said to have muttered something like "too much is just enough" and I am inclined to believe him. Is it possible, despite the mathmatic formulas to the contrary the C5AE 715 cfm carbs were just enough "too much".

I still refuse to go with a vacuum secondary but have any of you got an opinion of the 660 cfm Holley #4224. 50cc accelerator pumps, 25cc center squirter with 1:1 mechanical secondaries???
