Is the motor the same? Do they both have A/C or no A/C?
you have to drop exhaust be able to remove starter.
what are the factory timing specs for a 1977 chevy 454
Assuming you are talking about the Impala/Caprice, it's 115.9 inches.
All V8 Chevy plug gaps in 1977 was factory .045
No. Just a standard 305 with a 2 barrel carburetor.
Yes, 1977 light trucks are factory equipped with catalytic converters.
Factory would have been a 350 TURBO.
In 1961, the Impala SS (Super Sport) was introduced to the market. The Chevelle went out in 1977 during a Chevy downsizing, when all sedans took the Malibu name. since 1961 chevy has halted the production of the SS a few times. chevy made there first car in 1913, it was a 1914 royal mail roadster.
heck the Kelly Blue Book, on the internet
A/C plug # R45TS and it gaps at 0.045 That is the factory plug.
2 bolts hold it in and you have the hot wire from the battery to take off the starter and 2 small wires and just pull it out.
