I can confirm the blocks do crack under high boost, I used to have one in my car a few years back which did this. I also know other which had a cracked block
Some of the engines were also built by Vulcan engineering.
I would expect that GUZZLER has seen a few more system 2's than most people
and have a balanced view on them
I would personally take a good 1.6 CVH over a 1.9 CVH any day and i've had both, including engines using the US block
