CJK (man/auto?)

[Dan 37377]

CJK motor id. one book shows it as auto trans. any help on knowing hp/transmission that this ID should have been "originally"? also, would it have carried an iron manifold or alum? thanks.

Part of the "confusion" on this one may originate from the fact that some GM publications say that the "CJK" code was used for "1971 330 hp with THM-400". Of course, the 330 hp for 1971 was the LT-1 and they didn't build any with THM. So, we pretty much know that the GM reference is incorrect. But, I expect that the "THM-400" part of it is correct.

As far as I know, the "CJK" suffix code was used for later 1971s with base (270 hp) engine and THM-400 transmission.

thanks for help and clarification.

would there be any way a CJK/4-spd could have been correct (i.e. original from mfr.) in a '71?

It's VERY unlikely but, I suppose THEORETICALLY possible. The "CJK" engine would have ben delivered to St. Louis with no bellhousing, flywheel or clutch assembly and with an installed auto trans flexplate. Also, it would have had no pilot bushing installed in the crankshaft. For a "CJK" engine to have been used with a manual transmission, the folks at St. Louis would have had to remove the flex-plate, and install a bellhousing, flywheel, clutch assembly, and pilot bushing. The only way that they would even have had those parts in the plant would have been if they could have removed them from another engine.

Perhaps, they could have and would have done this in an EXTREME PINCH if they totally ran out of the "CJL" engines and they absolutely had to get a car built and shipped. I really doubt it, though.

Joe. Hope this info helps.. I had a CJK '71 (August 01-71) that I know for sure was the original engine. I owned the car 14 years. It was a base 270hp automatic. "010" block, Cast iron manifold with a Q-jet, Stamped steel valve covers. Mine had A/C.
