What Dave said - we need to know what else has been done to the engine. If it's stock, the Victor Jr will be a major disappointment as it's made for 3,500 - 8,000 RPM operating range and will be a big pig on a stocker.

In the stock form, an Edelbrock Performer with a Q-Jet is tough to beat for idle to 5500 RPM. A performer RPM and a Q-Jet works very well with headers and Flowmasters and breaths well to 6500 RPM.
