The Edelbrock manual is a real ++++ Nevada and if the OP has the patience and insight to get the carburetor adjusted correctly he will likely be happy with the performance. It often seems easier for a beginning DIYer to rebuild his first engine correctly than his first carburetor though.
Over the years customers have brought me cars and trucks that someone had attempted make some performance modifications which didn’t quite work out. A common problem was installing severely oversized Holley carburetors and my best solution to that was installing the correct size Edelbrock which performed like an OE carburetor. I seem to recall they cost less than $130 back in the good ole days.
