This pressure pushes the refrigerant through the rest of the system. 035″ Shaft nut torque on GM AC compressors is 12 ft/lbs ©, 2018 Rick Muscoplat. It would be nice to know a bit more about this Chevy’s engine’s prowess, its underside integrity and the “hardly” any rust comment but this example appears to be a pretty good foundation for a restoration of a very coveted Chevrolet muscle car.A6 compressor clutch. On the surface, it seems like a paint job could put this Chevelle back in tall cotton. The carpet, however, at least in the driver’s footwell, looks like it has seen water intrusion, an explanation for the two rust holes? The tachometer’s 6,000 RPM redline is another testament to the L78’s presence. The black vinyl upholstery is showing only the slightest signs of wear, remember that 56K mile claim and the Rosewood steering wheel, headliner, dash and instrument panel are in very nice shape. The interior belies the exterior’s condition – it looks quite good. Noise standards killed it off after the ’69 model year. Of note is the referenced “chambered exhaust” system, a really neat, mufflerless, seldomly seen option. Interestingly, the seller makes no mention if, or how, the engine runs but one image clearly shows the alternator spinning so at least the motor is in running condition. While an image of the engine’s number pad or a legitimate build sheet helps with the L78 authentication, knowing the code is beneficial and there is a correct Winters Foundry “snowflake” aluminum intake manifold attached to the top of the engine the air cleaner, however, is not original or correct. KF is the correct alpha code for Regular Production Option (RPO) L78, a 375 HP, 396 CI motor attached to a Turbo-Hydramatic 400, three-speed automatic transmission. While there is no image of the engine’s number pad, the seller does state the ID as being T0327KF which translates into Tonawanda, New York (one of Chevrolet’s engine foundries) and March 27th as the casting date. Rounding out the exterior is the complete trim (the plastic grille has a minor problem), still bright chrome bumpers and the correct Magnum style wheels. The included image of the trunk floor is not showing signs of anything more than surface rust – typical. He does reference two holes in the floor – both sound minor, and a cut-out in the firewall which appears to have been for a cowl-induction air feed. The finish is obviously shot but the body appears to be mostly rust-free (“hardly” any rust according to the seller), a major accomplishment for a GM “A” body of this generation, especially one, that based on its exterior appearance, has seen substantial outside time. The seller states that this 56K mile Chevelle belonged to a friend who purchased it new and stopped driving it in the early ’80s – no reason given as to why. One big difference between ’68 and ’69 was the inclusion of a three-speed automatic transmission as an option in ’69 ’68s and earlier model years only utilized a manual transmission. That is about twice the number assembled in 1968 and an increasingly popular option in spite of the fact that it was not advertised, referenced or promoted. The seller correctly states that this Chevelle is one of 9,486 L78 versions produced for the ’69 model year. It is located in Kenwick, Washington and is available, here on Facebook Marketplace for $31,500. ![]() This find appears to be rather intact, so let’s look at it closely. It seems that when one of these turns up it is either a number 1 condition, trailer queen specimen, as in completely restored to the hilt or a “youstabee” that has long since lost its original engine and a lot of other important stuff. While the 1969 Chevrolet Chevelle SS396 was certainly Chevy’s mid-size go-to muscle car in that august year, the L78 equipped version with its 375 HP engine was the holy grail.
