What's the benefit of a cross bolted RV8?

I'm no engineer, so keep it simple please! Looking at RV8 engined cars and this does get mentioned. Which cars are and which cars aren't and what is the benefit in layman's language?

It increases the block strength and potential for power by keeping the crankshaft more stable at higher revs and under heavy load, as a stable crankshaft will twist and deflect less under heavy load, so it will be far less likely to break than a less stable one.

Thank you. Is it more essential with modified cars? When were they fitted as standard?

Cheers guys.

So a 450 engine is likely to be more robust than an early 500 engine then?

Yes and the Rangie 4.6 is the most robust, cross bolted and bigger journals.

Don't they tend to suffer from a cracked engine block?
