In order to gain engine compartment clearance, big block (BB) engines were offset 1/2 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 in the different applications and different years, but are functionally the same within a grouping. The original frame mount part numbers are listed.

Quoting from the Chevrolet Dealer Service Information Bulletin, 69-I-1, dated 19 Sept, 1968:
|
Most service parts were produced specifically for service. Production engines and transmissions were generally not used as service parts.
| 1967 BB with smog RH Valve Cover w/ bracket |
Stant Oil Cap | |
|
|
The Camaro big block valve covers used on the 396 and 427 engines were basically the same for 1967 through 1969. They had the same shape and all had oil drippers spot-welded on the inside of the cover which created the "dimples" on the outside of the cover. But the brackets attached to the valve covers changed every year.
Righthand - The righthand side valve covers were similar all three years.
The oil cap was located on the righthand valve cover and was a twist-on style
(later valve covers used a push-in rubber plug). The 1967 396 with smog had
a one-year-only unique cover which had a bracket on the valve cover
for the fuel mixture control valve.
Both 67 396 (with and without smog) RH valve covers have the spark plug wire stand
welded in the center of the valve cover. Whereas the 68 and 69 RH valve covers have
the spark plug wire stand located rearward, almost directly under the crankcase
vent tube hole.
Lefthand - The lefthand side big block valve covers had three features in common all three years - a slanted end for wiper motor clearance when removing the cover, a dimple for rocker arm clearance and for the oil dripper inside the valve cover, and the rear spark plug wire stand located forward of the rear bolt hole, also to clear the wiper motor. Both Camaros and Nova had the spark plug wire stand in this location. Chevelles and full-size Chevrolets had the stand rearward of the rear bolt hole.

The changes in the LH valve cover are all related to the temperature sender wiring. In 1967, the sender was mounted in the front of the intake and there were two temperature sender wire clip tabs along the intake side of the valve cover for routing the wiring. In 1968, there are no clips on the valve cover because the temperature sender was in the head and the wiring was part of the alternator harness. In 1969, the alternator moved to the other side of the engine and the temperature sender wire came out at the firewall and down the exhaust manifold side to the temperature sender in the head. The 69 BB valve cover had one wire tab (which was dip-coated with plastic) on the exhaust manifold side of the valve cover for this wiring.

67-69 L6: 1115208
67 V8:
1115267 - used on many applications including LF7(base 327), L35, and L78.
1115270 and another coil (possibly 290) - used on L30 and SS350 cars. It apppears that the
ignition resistance wire changed from 1.8 ohm to 1.3 ohm in production and so the coil may be an
early vs late usage.
68 V8:
1115293 - all engines except Z28
1115202 - early Z28
1115298 - late Z28 (changeover was about Jan 68)
69 V8:
1115293 - used on all engines except below
1115298 - Z28
1115270 - small block (Z28 and SS350) with cowl hood
1115210 - ZL1 TI units

Chevrolet had two basic starter designs that were used from 1963 to 1985. The size of the
ring gear on the flexplate or flywheel determined which starter design was used.
- The smaller 153-tooth ring gear was 12.75 inches in diameter. This design used a starter
with the straight-line mounting bolt housing made of aluminum, with 2 different length bolts.
Manual transmission cars used the 403 bellhousing.
- The larger 168-tooth ring gear was 14 inches in diameter. It used a starter with a
staggered mounting bolt housing made of cast-iron, with equal length bolts. Manual
transmission cars used the 621 bellhousing.
The listings for starters in GM documentation vary significantly and part numbers were consolidated for service to reduce the number of service parts; we are not addressing either service part use or physically interchangeable parts. The difference between starters, that were otherwise the same external form and fit, is the torque output due to different internal component parts.
The starter usages below have all been confirmed via original cars or production
documentation (e.g. the AIM and chassis broadcast sheets).
Here are a few notations about the applications.
- MT = manual transmission, AT = automatic transmission.
- The starter for a 1967 L6 with an automatic transmission has not been confirmed.
- The starter used on the 1967 327's changed mid-way through the year. There is not
enough data yet to pin down the changeover date beyond that it happened in the spring of 67.
- The 69 SS350 with automatic transmission had a hot restart issue. A
TSB was issued with information
about a service fix and a change in the factory starter. The change occurred before November 1968.
- The ZL1 with manual transmission used the smaller and lighter (15#) L88 flywheel which
had less inertia and provided better engine response on the track.
