Lol no Cosworth, to my knowledge, has failed yet. It is the built OEM blocks that are 704 castings that are failing. I didn't say Cosworth :P

What sparked this discussion is that it was brought to my attention, that when considering a short block replacement with a built OEM block, that the newer 704 castings are failing even right on the dyno after being built by reputable shops and builders. I know of 4 total, one in my area that died on the dyno right after install. Research was conducted and it wasn't anything besides the cylinder wall.

I mentioned Cosworth because I am getting this block over the original portion of building a new OEM block. That and Cosworth stands behind their product ^_____^
