Curious why an iron block, do you feel an iron block can withstand the power your combination will make ? The V30 can make 2500hp.
I would think you would want to run an Indy or Keith or another brand aluminum block. I have a mega block with a screw charger and am afraid to turn up the boost because machine shop told me my mega block will break if I turn it up despite having thick cylinders.. they think my mega block is the weak link.
I am using center bob crank to help cap walk and not going past 7000 rpm but would really like to know how they determined the hp rating of a cast iron block like the Koleno or MP wedge mega block.

If it was true it would not make sense to use an iron block if your going to make 2500 hp unless you can get away with it because of a the gradual ramp in power turbos /centrifugal chargers have vs screw charger which is all in at the release of the brake.

Thanks
