Called Summit yesterday, and they were available. They do cost about $ 170 more that the Edelbrocks so I don't know if they are worth the extra bucks for a street car, but they seem impressive as they flow a little more (compared both flow charts) even though they have 20 cc's less in intake volume (maybe because of the bigger intake valve).
I'll be using an RPM intake (already got that one) so my other concern will be matching the runners to the intake ports...
Any more info will be appreciated as I am on a hurry!!
