Re: 1967 L35 SMOG question
 

From what I'm seeing on the Google, the Impala pump on my buddy's old Impala L35 engine is the same as a '67 L78 Camaro pump. Same hose connections, all three hoses, on the back of the pump. Z/28 too. L35 seems to have the two hoses from the AIR pipes on the exhaust manifolds connecting to the bottom of the smog pump. '67 assembly manual shows this too--the L78 and Z using the same pump connections as on the old Impala engine but the L35 having two of the connections on the bottom of the pump. A pump for sale on Heartbeat City for '67 Camaro L35 shows the connections on the bottom also.
