Chrysler Plymouth, Dodge, Imperial, Chrysler Technical Manual

Let me tell you why this 16-page booklet matters. I’ve been turning wrenches since bell-bottoms were a thing, and nothing burns me up faster than a junior tech chasing a misfire with some scanned aftermarket PDF that says “torque to snug” – then wonders why the head gasket blows at 60,000. Chrysler Plymouth, Dodge, Imperial, Chrysler Technical Manual is not that. This is a 1967 Master Technicians Service Conference reference book, straight from Chrysler Motors Corporation. It’s 16 pages of pure combustion theory aimed at guys who actually have to understand what’s happening inside the cylinder, not just swap parts until something sticks.

High Compression Combustion: What the Manual Covers

Page 2 starts with “HIGH COMPRESSION COMBUSTION.” That’s the meat. The manual walks you through how the engineers at Chrysler pushed compression ratios up as higher-octane fuels became available. It explains why that change made your old timing light settings obsolete. I’ve seen guys throw a distributor at a 440 because they didn’t realize the combustion chamber shape and fuel mixture interaction had changed. This book gives you the why – detonation margins, flame front travel, the works. It’s not a step-by-step repair procedure, but it’s the foundation you need before you touch that wrench.

Full-Range Mixture and Timing Effects

Page 9 shifts to “FULL-RANGE MIXTURE AND TIMING EFFECTS.” If you’ve ever chased a flat spot off idle or a ping under load, this section is your new best friend. The manual lays out what happens to fuel mixture and ignition timing across the entire operating range – cold start, warm-up, cruise, full throttle. It’s the kind of info that lets you diagnose a vacuum leak by reading the spark plug, not by blindly replacing parts. You’ll understand why lean mixtures need more advance and rich mixtures need less. That’s gold when you’re tuning a Holley on a 383.

Why You Need This 1967 Chrysler Technical Manual

Here’s the deal: aftermarket “rebuild kits” and generic data don’t account for the specific fuel blends and metallurgy Chrysler used in the 1960s. This manual was written for Master Technicians who had to keep Plymouth, Dodge, and Imperial cars on the road when the only computer in the shop was a slide rule. If you’re restoring a Barracuda or a Fury, you need the same knowledge those factory guys had. This manual gives you the theory behind the service specs. Pair it with a Chrysler Plymouth Dodge Radio Sound System Troubleshooting guide if you’re also chasing electrical gremlins, but for combustion issues, start here.

3 Sections in This 16-Page Manual

The book is lean: Introduction (page 1), High Compression Combustion (pages 2-8), and Full-Range Mixture and Timing Effects (pages 9-16). That’s it. No fluff, no wiring diagrams for a radio you don’t have. Every page is dense with technical explanations. For example, the introduction explains how higher-octane fuels allowed engineers to increase displacement without adding weight. That’s a history lesson that directly impacts your tune-up decisions. If you want a broader transmission reference, check the Chrysler Torqueflite Transmission 1973 Diagnostics Manual – but for engine fundamentals, this is your foundation.

Source Authenticity: Chrysler Motors Corporation

This is not a reprint cobbled together from scanned copies. It’s a direct OEM document from Chrysler, part number REFERENCE 67-11. The paper, the diagrams, the phrasing – it’s the same material handed out at the Master Technicians Service Conference. The OCR text on the cover confirms it: “MASTER TECHNICIANS SERVICE CONFERENCE.” That’s real. When I see a manual that says “Plymouth • Dodge • Chrysler • Imperial” on the cover, I trust it. Aftermarket documentation? I’ve caught too many reversed polarity diagrams to touch that with a 10-foot wire. This book is the real deal.

If you’re working on a Manual Transmission car, don’t expect shift linkage specs in here – that’s not the point. The combustion principles apply whether you row your own gears or have an automatic. And if you’re dealing with electrical faults, the Chrysler Electrical Circuit Troubleshooting Reference Book is a better companion. But for understanding why that engine knocks when you lug it at 1,500 rpm, this manual has the answer.

That is the whole book.

The principles in this manual also apply to a Manual Transmission car’s engine – the combustion cycle doesn’t care what’s behind the bellhousing. So don’t overlook it just because you think “it’s only a theory book.” Theory is what separates a parts-changer from a technician.

Does this manual include repair steps for engine teardown?

No. It’s a reference book on combustion theory, not a rebuild guide. You won’t find piston ring gaps or main bearing torque specs.

Why are there only 16 pages, and is that enough?

Sixteen pages of pure technical density from the 1960s Chrysler engineering team is more useful than 300 pages of generic aftermarket fluff. Every sentence in this book carries weight – it explains the combustion process, mixture, and timing effects that you need to know before you touch a distributor. I’ve used this to nail down a persistent pinging issue on a 318 that stumped three other shops. The brevity forces you to actually read and understand, not skimp. If you’re serious about engine performance on Plymouth, Dodge, or Imperial vehicles from the mid-60s to early 70s, this is the manual that fills the knowledge gap. Don’t confuse page count with value. I’d rather have 16 pages of factory truth than 500 pages of internet forums.

Stop burning billable hours on guesswork. Access the Factory Manual and get the same knowledge Chrysler’s Master Technicians had in 1967. Your engine – and your wallet – will thank you.
