I agree...that's why I mentioned or should have mentioned If your going to spend the money on a aftermarket block an aluminum one is the way to go IMO...that's the reason I no longer run the mega block is for fear of having 4 or 5 dollars worth of scrap iron if something bad happened...that & when I sold mine they were not available...that's when I went to the current combination I have today...Aluminum Indy block 540 CI
