Small Block Chev Vintage Edelbrock STR10 Cross Ram. Street Tunnel Ram. Good for Street or Race, low for hood clearance. Edelbrock's version of the Factory Z/28 Cross Ram. It has new but used 600 Holley carbs I bought them new and ran it on the street for about 3 years no choke on either carb. It has been ceramic coated. The gasket on it is useable but I have a new one also. New throttle linkage works smooth and easy. No shipping too big and heavy.
