Will Ported 308 Dart Iron Eagles work on a 565CI or even 582Ci motor?
 

Max RPM would be 5600. Wondering if anyone has tried this combo.
Also, can a 4.375" stroker crank fit in the Gen 6 Mercruiser block?

Thanks Gary

The heads will work.

I would stick with a 4.25 565ci standard deck combo, just my opinion though

not sure about a 4.600 bore on a production gen6 block but if the block get sonic tested and the cylinder walls are thick enough i guess it would work.maybe a 540 would be a better choice.
