Why when looking at a lot of intakes for camaros / SB Chevy engines do a lot of parts have a date range of "fits blocks up to 1986"? what did they change for '87 that makes em not fit?
Want to know cos I have a 87 Z-28 with the 305ci Carb engine.

Starting in 1987 they used a 1 piece rear main seal, hydraulic roller lifters and cam and the center 2 bolt holes on the intake manifold are at a different angle (except corvette alumnium heads) and a small cap HEI distributor with a remote coil.

u sure its a carb engine? i thought that all camaros went fuel injection in '86 or '87... it could be a tbi actually, tbi's look sorta like carbs...

Historical Footnotes On The 1987 Camaro

Robert D. Burger continued as Chevrolet's general manager during 1987. Model-year sales fell from 173,674 in 1986 to 122,761 in 1987. Calendar year sales also wound up lower at 117,324 or 4.9% of the industry total. Model-year production of 137,760 Camaro's represented a 1.87% share of the industry's total. The Van Nuys plant reported building 51,936 Camaro's (and 35,610 Firebirds). The Norwood factory reported building 85,824 Camaro's (and 53,013 Firebirds). This would be the last year of operation for the Norwood plant.

Of the Camaro's built, 83.6% had automatic transmission, 16.4% had a 5-speed manual transmission, 26.7% were equipped with a V8 engine with a carburetor, 29.4% were equipped with a fuel-injected V8 engine, and 43.9% were equipped with a fuel-injected V6 engine.

100% (All) had power steering, 82.7% had power front disc brakes, 17.3% had power 4-wheel disc brakes, 29.6% had a limited-slip differential, 100% (All) had steel-belted radial tires, 47.2% had power door locks, 48.1% had power windows, 100% (All) had reclining bucket seats, 22.7% had a power front driver's seat, 78.2% had tilt steering, 94.6% had all-tinted glass, 90.4% had manual air conditioning, 56.7% had cruise control, 66% had delay windshield wipers, 3% had a conventional AM radio, 0.7% had an ETR AM radio, 15.8% had an ETR AM/FM radio, 51.1% had a ETR stereo cassette player, 6.2% had a Bose/JBL sound system, 19.8% had a premium sound system, 93.6% had a digital clock, 62.5% had an electric rear window defogger, 0.7% had a rear window wiper, 100% (All) had a remote-control left-hand outside rear-view mirror, 22.8% also had a remote-control right-hand outside rear-view mirror, 47.1% had aluminum styled wheels and 44% had T-tops.

A total of 116,656 new Camaro's were registered in the U.S. during calendar year 1987. That was down from 165,883 in 1986. With the closing of the General Motors Assembly Division plant in Norwood, Ohio, the only remaining source of Camaro's and Firebirds after 1987 was the Van Nuys, California, factory. GM also cancelled its GM80 development program for plastic-bodied, front-wheel-drivc Camaro's and Firebirds, and industry observers began to speculate that the end of both nameplates was in sight. As we now know, it would take 15 years for the end to arrive, but in 1987 the speculation alone was enough to lead to a reduction of models for 1988. As a result, only the base Sport Coupe and IROC-Z were marketed in model year 1988.

basicly for the question of intake compatability, its the angle of the center four bolt holes. the angle changed in 87.
