Unlike Professor Ron, you
can provide some factual GM information. I must be reading-challenged-I still can't find where his point was on a GM- supported product that they won't use in production.
The 289 was a steam hole-dependent design too. Yes the LS' also because of the partitioning in the jackets around the bores. That problem was solved by World's Warhawk LS blocks which surrounded all four of the siamesed bores with water.
