I have a 67 SS convertible. It has an EF coded numbers matching pad. The intake is the Q-jet spread bore style and I got it with a closed original air cleaner with a weathered but ledgable 350 hp decal. The carb is a stick carb and the distrib is a 1111169. I have seen original 350 hp cars with holleys on them as well but they all seem to have open air cleaners. My intake casting date is matching as far as being cast as the same week as the block. The question is were there two styles of 350 hp engines and can you spot them by if they have an open or closed element? Second question: Did non A.I.R. cars use exhaust manifolds with square plugs in port tubes? I have found so many originals this way and have to think they are correct.

Look forward to the input on these questions. Regards, Jim Keegan

According to my books the EF code is a 67 350 HP manual trans non smog engine. I could be wrong I know there are far more knowledgeable guys on here than me but I thought all the 67 350 hp cars were Holley intakes and Holley carbs with open element breathers. Also according to my book the 169 distributor is for "all" 396 325 hp or 350 hp with smog applications and I don't think non smog cars had the plugs or holes. There were smog and non smog exhaust manifolds. Really like your car, got one myself

Sounds like you have a mixed collection of parts, or maybe a 325HP A.I.R. engine that has been re-stamped. The EF engine should have a Holley and open air cleaner. The Quadrajet and closed air cleaner were 325HP only that year. The 350HP engine didn't get a Quadrajet until 1968, but still used an open air cleaner. No A.I.R. on the EF engine; the exhaust manifolds should not be drilled for the smog tubes.

Where was the car built? I would expect to find A.I.R. (smog pump) components only on a 1967 Chevelle built at the Fremont assembly plant.

Car is a Kansas City Car 200,000 serial number and has most of it subcomponents dated around the same time.
