Ramvan, I don't pretend to know it all, but what I do know, I know very well. I'm not out to attack you or anything like that. This is not personal. You are enthusiastic, and that's a good thing. However, you are also in waaaay over your head. The 426 had 10.25 to 1 compression. The diesel in my boat is 22.5:1. Neither had a turbo. Both have forged aluminum pistons. What do you think happens when the boost comes up? Cylinder pressure increases. Simple as that. So be it 10:1, 22:1 or 8:1 with 10 lbs boost, it's all the same. There's more stress than a cast piston can handle, forged must be used.
