Listing of Factory Camaro Engines
Part of the success of the Camaro was the wide variety of engine
options that were available. Here's a summary of the factory domestic
engines and their availablity. (Other engines were used in export models,
foreign-built models, and dealer-modified Camaros.)
A complete listing of engine codes
is shown on the Drivetrain Decoding page.

The 302 and the Camaro Z-28
The 302 engine was only available in first-generation Z-28s (the 350
LT-1 was used in 2nd generation Z-28s), and was created in response to
a Trans Am racing engine displacement limitation at that time of 5
liters (305ci). The 302 was created by installing a short-stroke 283ci
engine crankshaft in a 327ci block, resulting in 302ci displacement. This
just fit the Trans Am limitation (the bores of the actual racing engines were
tweaked to produce exactly 305ci) and this design (with special
modifications for high-performance use) resulted in an unusual,
high-revving engine that helped create the legend of the Z-28. The 302
was the only engine available in the first-generation Z-28.
Differences in V8 Frame Mount Brackets and Engine Mounts
All '67-'68 small-block (SB) and '69 307ci and 327ci engines
used the same frame mount bracket (approximately 2-1/2 inches wide)
attached to the subframe. The 1969 302ci and 350ci engines
used a shorter (~3/8 inch) and narrower (~1/4 inch) bracket.
1967-68 engine mounts will assemble to the 1969 302/350 engine mount
bracket, but this is an incorrect assembly that results in driveline
vibration and clutch chatter because the engine sits too low and can
move on the bracket.
In order to gain engine compartment clearance, big block (BB) engines
were offset 1 inch to the right
(towards the passenger side) by means of asymmetric brackets. 1967-68
BB frame mount brackets are 2-1/2 inches wide (but not the same as
SB) and use the same engine mounts as 67-68 302ci and 350ci.
For 69, BB frame mount brackets were redesigned to use the new
thicker, narrower, engine mount also used by 302ci and 350ci. BBC
bracket pairs are easily spotted because the left bracket is noticeably
taller than the right in order to achieve the engine offset.
Note that the frame mount brackets and the engine mounts below are grouped
together by functionality. The OEM engine mounts may have had different part
numbers, but are functionally the same.
The original frame mount part numbers are listed.

Service Engine (CE) and Transmission Coding
Quoting from the Chevrolet Dealer Service Information Bulletin, 69-I-1,
dated 19 Sept, 1968:
The following system will be used to identify service engine and
transmission assemblies* including replacement parts. Manufacturing
plants will number each assembly as it is produce.
The first letter will designate the GM division which produced the
engine.
C-Chevrolet L-Oldsmobile
K-Cadillac B-Buick P-Pontiac
The second letter will designate the type of unit "E" engine
or "T" transmission. The number following the letter will
designate the model year "9" for 1969. The last five digits
specify the service replacement unit sequence number. The
group of numbers to be used by Chevrolet manufacturing
plants are as follows:
Engines
Flint Motor Plant (L6 Engines) 00001 to 19999
80001 to 89999
Flint V8 Engine Plant 20000 to 49999
Tonawanda Motor Plant 50000 to 79999
Example: Number CE900175 designates Chevrolet engine - 1969
year, and the 175th unit produced for service at the Flint
Motor Plant (L6).
Transmissions
Cleveland Transmission Plant 00001 to 14999
Toledo Transmission Plant 15000 to 24999
Saginaw Transmission Plant 25000 to 34999
Muncie Transmission Plant 35000 to 44999
Hydra-Matic transmissions will be numbered with the letter "H"
regardless of the G.M. Division using the transmission.
* This numbering system applies to service engine assemblies,
partial engines, fitted cylinder cases, cylinder cases,
transmission assemblies and transmission cases.

Most service parts were produced specifically for service.
Production engines and transmissions were generally not used as service parts.
