4k With 3k Crank. Anyone Done It?

I was just wondering if anyone has built a 4K with a 3K crank?

 

We have a 4K motor with a cracked crank and we were thinking of rebuilding it with the 3K crank to create a destroked motor that would thus rev to the sky.

 

I know it would drop the compression, but we have a 3K head that has been decked 4mm, with oversize valves and HDuty valve springs, with a port matched manifold and 45mm webber.

 

 

What are your thoughts and experiences?

:wink: do the maths

Thanks for the PMs.

 

I should really search first. 3K crank turns it to a 3K again

 

Oh well, the search is on for a 4K crank now
