1978 Jeep CJ-7

1978 Jeep CJ-7 304 V8, Lifted, Open-Air Build with Clean Undercarriage


Why This Car Is Special

The 1978 Jeep CJ-7 holds a specific place in off-road history that is easy to overlook until you start digging into the numbers. Introduced for the 1976 model year, the CJ-7 was Jeep's answer to buyers who wanted more interior room and usability than the shorter CJ-5 could offer. The CJ-7 stretched the wheelbase to 93.4 inches, giving it a longer body, proper room for a rear seat, and the ability to accept an optional automatic transmission or hardtop none of which worked well on the CJ-5 platform. By 1978, Jeep had refined the CJ-7 into one of the most capable factory off-road vehicles available in America, and the optional 304 cubic inch V8 was the engine serious buyers checked on the order sheet.

This particular 1978 Jeep CJ-7 is finished in silver over a black vinyl interior and has been built out as a capable, trail-ready open-air vehicle rather than a showpiece. The VIN decodes to confirm it as a 1978 CJ-7 body style with V8 power the 'H' position in the VIN identifies the 304 V8 as the installed engine. The undercarriage photos tell the more important story here: the frame and floor pan are solid and well-coated, which is the first thing any knowledgeable buyer should verify on a 46-year-old Jeep. Clean metal underneath means you are starting from a sound foundation, not inheriting someone else's rust repair project.

The build on this CJ-7 is sensible and deliberate. It is not over-modified to the point where drivability suffers, but it has been upgraded in all the right areas suspension, tires, bumpers, and recovery gear so it is ready to use without a list of items to sort out first.

Mechanical

The engine in this 1978 Jeep CJ-7 is the AMC 304 V8, a 304 cubic inch unit that was the top V8 option Jeep offered in the CJ series during this era. AMC developed this engine as part of their 290-343-390-401 family, and the 304 was specifically tuned for use in lighter vehicles where its smaller displacement still delivered strong torque at low RPM exactly what you want when crawling over rocks or pulling through soft terrain. From the factory, the 304 made approximately 130 horsepower in its 1978 state of tune, which sounds modest by modern numbers but delivered its torque low in the rev range where off-road driving actually happens.

This CJ-7's 304 has been fitted with an Edelbrock carburetor and Edelbrock air cleaner, two of the most respected names in bolt-on performance for American V8s. Edelbrock carburetors are known for reliable cold-start behavior, consistent fuel delivery, and ease of tuning all practical advantages on a vehicle that sees real-world use rather than just weekend shows. The combination keeps the engine responsive without requiring exotic parts to maintain it.

The 3-speed manual transmission is the correct pairing for a working CJ-7. It keeps the drivetrain simple, the parts accessible, and gives the driver direct mechanical control over the vehicle in technical off-road situations. Power steering and a power brake booster round out the drivetrain in a way that makes this Je
