265 hemi straight six

Nope. Some Hemi-6 blocks, not all of them, will accept an A/LA-pattern bellhousing, because the A904LA Torqueflite was used in 6-cylinder Valiant VIPs, instead of the crude BW35 used in less-ritzy Valiants. But TTBOMK there aren't any Hemi-6 blocks that will accept a Slant-6 bellhousing.
Yep, agreed, But as I said "Some" as in the Distant past I'd mated up a Torque flight to a Hemi 6. Maybe No Slant bellhousings bolted up in Australia, but in NZ the late Slants did, just before the new 245 was released ( Something to do with a delay in Component supply )...Go Ask a Brazilian too , as an aside. AU wasn't the center of the world when it came to /6's, Hemi 6's & various trans & bell housing.
Cheers Digger.
