I've only freshend one of these first hand so what I saw was as mentioned, weak in the web, and deck. I have seen 2 broken ones, and one so poorly machined that the rear main seal top, and bottom could not physically align.The broken ones were in spray use, but nothing a good mega block couldn't have taken (maybe 1400hp). Like without a diaper they could have ran the crank over. Some said it was sub par studs, but the look to me was weak block, in the deck too.



This is all true


I e-mailed Bill Mitchell and got an immediate reply: These new blocks have been proven to 2000 HP with no issues.

Sounds strong enough for me, and comes without the Indy attitude, and the extra $1500 for a KB that you can't get anyway.
