small block to big block

There's a gent on the Australian Mopar Board that made up a Big to Small block adapter a couple of years ago. It's not that hard. He said:

"Hi Greg,
It is working a treat,no issues.
Biggest hurdle is having to trim the left ear off the block and modifying the headers to drop lower than the starter.
If your going for standard manifolds and a new exhaust it will not be an issue.
When i made mine i did 2 sets,sold the other to a guy for $400 but i think i may have shortchanged myself a bit.
I have another guy interested down the track for a kit so i will do a couple whenever someone else want one.
Would i do it again?Yes.

Cheers Wayne"

Of course, down under, they've got a lot of stuff we don't have:
