I broke my older Mopar Mega block.Ran it since around 1999 i believe and it was a Great piece.
So i am in the market and want another cast block.
Which cast block are you guys running at that HP level? A new mega block? World?
Thanks

I have both the 4.490 rough bored World block and the newer high nickel Koleno block that Koffels Place sells, 1200+ HP would be the Koleno block  I really wish someone would make a Mopar wedge or Hemiroid Compact Graphite Iron block

I thought Kolenco made a Compact Graphite Iron block?

That's why I bought a KB block
Plus you can fix it if something goes wrong 
 Good to go off the crate in my case.

Thanks for the responses.. I lost internet access not long after i posted.. I was looking at a cast block because we beat the heck out of this Mega block and it stayed together for years.(until it over revved)
Plus i have read about some of the long wait times to get a KB block. And would like to be ready to race asap.

What was the block failure from over rev? Could it be repaired?

No repair! Shot two rods out the side into the diaper. From what we can tell the converter bolts were over tightened ..stretched and sheared. Not a fun day.
