mod5v and 6T9 GTS were only .030 over though. Could these blocks be failing when pushed over 450 hp with a stroker crank? What could account for this? I find it hard to believe that side loading would cause this. There's a lot of 4" stroke engines of all makes that have not experienced catastrophic failure of this sort. Porous casting maybe? Rust from 35 years of negligence?
69GTS, I'm very interested in your photos. I would like to see what the cylinder wall mics out at the point of failure, what the busted out cylinder wall looks like and I'd also like to see pics of the rod too.
modv5, do you have any pictures you would like to share?
