Regulations trimmed a legendary engine's output that year.
Buyers paid more that year for noticeably less power.
Decades later, somebody reversed that math completely.
The compression ratio dropped from 10.3:1 to 8.5:1. The intake valve diameter was reduced to 1.88 inches. Midway through that same year, the entire industry changed the way horsepower was measured; this change caused engines to appear weaker on paper, even though the hardware itself had hardly changed at all. Chrysler's 340 small-block engine took all three hits at once, dropping from 275 gross horsepower the previous year to 240 net horsepower for this model year—even though the base list price actually rose slightly during the same period.
None of this was actually the engine's fault. Insurance companies were making the cost of owning big-block vehicles prohibitive, emissions regulations were tightening with every cycle, and automakers were struggling to maintain any semblance of a performance image within the shrinking permissible limits. A lightweight, compact coupe with a powerful small-block engine became the industry's answer—fast on the straight, cheap to insure, and for several years, one of the last truly fast cars that could still be purchased on a normal budget.
None of these constraints applied to the version produced decades later. The small-block engine in question, stroked out to 418 cubic inches, now produces approximately 530 horsepower and 560 lb-ft of torque; it is paired with a 5-speed manual transmission instead of the standard 3-speed manual. A narrowed rear axle, a locking differential, and a significant brake upgrade keep this power under control on a chassis that the manufacturer did not design to handle it. Each panel has undergone a rotisserie-level repainting process, including seam sealant, and is finished in black with a white pearl stripe running the length of the hood.
Once forced to reduce its power output due to federal bureaucracy, this body now produces more than twice the power allowed by its own regulators—and while it's decades overdue, the record has finally been set straight.
