Default Re: Question about BB 4speed crossmember

[ QUOTE ]
Good info here Gents on a much over-looked topic. Allow me to add a little more:

The OEM shifter mounting holes are different relative to the tranny mounting holes on big block xmembers. They are offset to the left about 1/4" compared to SB. This allows the BB shifter linkage to align correctly. Yes, a mismatch will work, but thats not the way they were from the factory.

This applys only to 67-8 Camaros.

[/ QUOTE ]

69 only has a similar issue. The shifter rods are about
1/3" longer to accomodate the mounting of the shifter with
that special ( again, BB only ) horseshoe mounting plate.

69 BB's have lots of these accociated issues. The lower
reverse lockout rod is also different for BB 4-speeds.
The flat nut for the Hurst shifter adjustment is a racetrack
shape vs. the rectangular shape of the SB's. Once you start
you just can't stop.

I hear ya! We actually don't know why GM installed the BB transmission crossmember with the LT1 application. We have confirmed that the engine mounts are indeed the SB version, and the crossmember is not the Pontiac version. I wish I could tell you why, but.... that's GM

We have speculated that the BB Xmember was retained under the COPO 9737 package because that package had been applicable to only BB cars for the prior two years, but we agree that it's a stretch and pure speculation.

The deuces actually have the BB shifter rods, but the SB shifter attaching bracket (no 1/2" offset), along with the '69 Camaro Z28 shifter mechanism with a Pontiac GTO bench seat arm. Confused yet?
