Hey Wedge, When you gave me that number for the carb. I looked in Jegs and Summit for it and also Edlebrock and there was no such number! Then I got my Rochestor book in the mail and sure enough in the back of the book they show the Edlebrock Performer that you have and it goes on to say what a good carb it is for performance. I was so excited I called Edlelbrock to get one and they informed me that they discontinued that one 3 yrs. ago. Back to the drawing board. The book is very good so after I finish reading it I guess I'll have to modify the one I have and hope for the best.
