EDM engine suffix code BBC 1973 .Any ideas?

[Astock]

The pad reads:T0929EDM 4 bolt mains with windage tray studs and the extra hole by the oil filter.The casting number on the block is 3999289.It's on it's first rebuild from the crate.Any help would be appreciated.

Casting is 72-78 454. . What a wacky week of numbers....any more numbers on pad or other? . May be a counter or marine motor if no other numbers? .

"The pad reads:T0929EDM"

Same build date as the last two suspected marine engines. Strange stuff lately. http://www.yenko.net/ubbthreads/images/graemlins/dunno.gif
