Goes back to Steve Morris.....He is of the same thinking in that the 90* cross bolts the KB blocks use do little against the direction of the load on the caps.I think you will see more aftermarket blocks like this as they have proven good to +2khp already...


The OEMs beg to differ, and they have alot more actual Engineering behind their decisions.


They might have more data, but is it relevant? I mean these blocks are going to go way past any production Hp levels, so data at 500hp isn't really a factor at 1500hp. I have no data myself, but guys that blow these things up at that level.....They would know best at what holds together.
