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 litres (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 Engine Mounts and Frame Mount Brackets

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 engine mounts and the frame mount brackets below are grouped together by functionality. The OEM parts may have had different part numbers, but are functionally the same.

Coding of Replacement Engines and Transmissions

Quoting from the Chevrolet Dealer Service Information Bulletin, 69-I-1, dated 19 Sept, 1968:
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 [for engines] are as follows: 

Flint motor plant (L-6 engines) 00001 to 19999
Flint V-8 engine plant 20000 to 49999
Tonowanda 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.

This numbering system applies to service engine assemblies, partial engines, fitted cylinder cases, cylinder cases, transmission assemblies and transmission cases.

Hydra-Matic transmissions will be numbered with the letter "H" regardless of the G.M. Division using the transmission.

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