Chevrolet Corvette RPO Codes — 1968–1982 (C3)
Part 2 of 2 of the Corvette RPO reference (see corvette.md for the index
and corvette-c1-c2.md for 1960–1967).
Famous C3 options at a glance: L88 427 race engine (1968: 80 built; 1969: 116); ZL1 all-aluminum 427 (1969: 2 built at $4,718.35 — the option cost more than the base car); LT1 solid-lifter 350 (1970–72) and the ZR1 Special Purpose LT1 package (25 / 8 / 20 built 1970–72); LS6 454/425 (1971: 188 built) and its ZR2 package (12 built, 1971 only); the announced but never-produced 1970 LS7 454/460; the 1978 Indy Pace Car replica (6,502 built) and Silver Anniversary paint B2Z; and the 1982 Collector Edition hatchback (6,759 built). Horsepower ratings are SAE gross through 1971 and SAE net from 1972 on — the big 1972 "drops" are mostly the rating change, not detuning.
Notes format: original option price and production count are given as
"$XXX.XX; N built" where sources supply them. Confidence per README:
confirmed = 2+ independent sources, single-source, disputed.
Year 1968
Famous option — L88 ($947.90; 80 built): second of three L88 years. Note: 1968 had no factory side-mount exhaust — N11 "off road" (under-car) was the exhaust option; side-mount N14 is 1969-only on the C3.

Year 1972
Famous option — ZR1's final year ($1,010.05; 20 built; 53 ZR1s total 1970–72) and the last LT1 (1,741 built). 1972 was the first year GM quoted only SAE net horsepower — the apparent drops vs 1971 (LT1 330→255, LS5 365→270, base 270→200) are largely the rating-method change. The UA6 alarm left the option list because it became standard equipment on all 1972 Corvettes.

Cross-year notes (1973–1982)
- 1978 Pace Car / Silver Anniversary: the Indy 500 Pace Car replica was sold as distinct model number 1YZ87/78 ($13,653.21; 6,502 built; internal designation Z78); B2Z Silver Anniversary two-tone paint ($399; 15,283 built) required aluminum wheels and sport mirrors.
- 1982 Collector Edition: sold as distinct model number 1YY07 ($22,537.59; 6,759 built) — a lifting-glass hatchback body style with silver-beige paint, turbine wheels, and a unique VIN character — not an ordinary RPO.
- Engine narrowing: LS4 454 ended after 1974 (last big-block); L82 ended after 1980; 1981 offered only L81; 1982 offered only L83 Cross-Fire Injection with automatic only (first fuel-injected Corvette since 1965, no manual available).
- ZR-prefix codes: none offered 1973–1982 (ZR1/ZR2 ended in 1971/1972).
- Corvette Action Center's 1982 page repeats several of its own 1981 price/production figures (D84, DG7, FE7, K35); those rows are marked disputed with both readings shown.

Factory kits (T1)
GM Heritage OCR kits (each bundles the Corvette Black Book option summary plus
factory dealer price schedules, "Regular Production Options" / "Extra Cost
Equipment" spec pages, and dealer order-guide "Alphabetical Option Index"
pages). Used to upgrade rows to confirmed and to resolve disputes; <span class="doc-cite">⛭ GM Heritage — …</span>
citations in the tables above give the page. G2-b (2026-10-01): the Corvette Black Book summary pages are a third-party book, not GM pages (S2). [HK] citations now point only at the kits' GM pages; prices and production counts taken from the Black Book are credited to it in the notes, and disputes the kit pass had settled on Black Book pages are open again unless a GM page settles them (row by row: docs/rpo/CLASSIC-HK-EDITS.tsv).
