Debunked by who? You. LOL The blocks we have here have different suffix numbers the 1's are always smooth with very little flashing on them. The higher numbers usually have large flashings and bad porosity. The end of the ladle always is the worst metal of the pour. I worked at a foundry in the Bethlehem steel in the 70's The best parts always came from the start of the ladle after scraping the slag from the top . The last of the pour was always dirty and cooler. It is usually the dirty iron not having the same flow Characteristics as it cools. The Higher numbers are the end of the pour. Also no quality control at the end of the pour testing the alloys.
You can see low grade metal when decking the block the finish doesn't have the shine. Same with LS vs new Hemi's . Ray Barton pointed it out to us The Hemis are very bad iron compared to the LS You can literally see the difference. That 318-11 picture in a prior post was sonic tested before it had the lifter hole repaired. Usually those blocks can go to 4.125 and even up to 4.200. That block was only good to 4.080 . some may be OK but usually the high numbers have issues.
Had seen a 340-10 block piston take out the whole cylinder 5 . All that was there were the head studs hanging through the head. Strong blocks do not need hard block installed. You can listen to the debunked theories . I am only stating what I have seen and I have seen many destroyed engines over the years. The 358 sprint car builders always hunted for 340-1's stronger platform.
I trade two standard clean 340-6's and up blocks for one 340-1 , Bring them to me. Pishta
