This is totally misleading. With the EQ's with 2.02" valves, they flow slightly less than the stock Edelbrock Performers except at .400" lift. They are very close in flows across the board with the Edelbrocks having a negligible edge.

With a full spring kit, the EQ's with 2.02' valves and their installed valve spring kit run around $1421 for a pair, including shipping here to VA. With the Autozone discounts that you can get, the Edelbrock 60779's complete are around $1422, shipped, and with 5% sales tax paid. This is HARDLY 2/3 the cost.....but you do have to time your purchase to catch the AZ discounts to get this Edelbrock pricing; the Hughes EQ prices are everyday prices.
