At 5 PSI on a stock-compression 350, Edelbrock's own testing produced 507 HP and 487 ft-lbs — numbers that will transform any SBC-powered muscle car or street rod into a genuine performer.\u003c\/p\u003e\u003ch3\u003eVehicle Fitment\u003c\/h3\u003e\u003cp\u003eDesigned for 1955–1986 Small Block Chevrolet engines, 302–400 CID.
