cross members

[Absinth]

Just out of interest, what is the difference between t400, t350 and trimatic? Is it just evolution? What is the actual difference in the cross members, just the shape?

Thanks for your help

Cheers

Basically,
T400 and T350 are US made GM Auto's....... Trimatic is Australian made GM Holden Auto... You can't fit a Trimatic box in place of a T400/T350 equipped 308 without an adapter or re-drilling the mounts on the engine.... 308's are drilled differently to accept either the Trimatic or the T400/T350.

Holden made the M15, M20, M21, M22 and Trimatic to all use the same crossmember mount... they are pretty much all interchangeable on Holden 6cyl and 8cyl..... without going into it too much.....

OZ may want to expand on the differences....

Thanks absinth - so that leads into my next question - 308 blocks match the cross members in terms of interchangability? - ie. blocks are either for all aussie boxes (trimatic M21 etc) or for turbo boxes? Hence "For sale - holden 308, turbo pattern' ? You can't then stick an m21 on a turbo block without an adapter?
