Done. If I knew how long this would take, might not have gotten this out.
This article doesn't mention anything about TRIUMPH/ROVER parts, and
I'd like to hear about them.

There is alot of mmaterial in this article about modifying the back
of the block for the 3.4" crank rear seal, turning the crank, modifying
the rods... If anyone really would like a copy, let me know.

With the records GROUP44 set and a motor setup like this,
We have serious Porsche eating material.
