Inliners International Forums Thread Like Summary - Anybody know anything about this insane car?

Is this similar to the chevy 250 inline 6 we commonly use?

It looks to be held in Argentina, so their version of the 250 is the same as the US. Brazil on the other hand has the same shortblock as the US, but their version uses a different cylinder head. And all of their versions produced more factory BHP than any of the US versions with the siamese intake ports.
