Edelbrock part #5061 Torker II 2-O intake manifold is designed for street 396-502 c.i.d. Chevy V8’s with large oval-port cylinder heads (1975 and earlier). Manifold not equipped with EGR. Will not fit “tall block” V8 engines. The Torker II 2-O intake manifold is a singe plane low rise intake that’s great for high performance applications that have limited hood clearance. The manifold has an exhaust crossover for easy cold weather warm-ups, but no provisions for exhaust heated chokes or EGR. Customers will need either electric or manual choke carburetors. Not for heavy vehicles (trucks, vans etc.); use Performer 2-O #2161.
