Help please, I blew my motor and need to plan the rebuild

BGTV8

That is a near- perfect example of failed big-end bearing seizing, tearing the gudgeon pin (little-end) out of the piston and then cutting the engine in 2 and generally self-destructing ........

You have an oil problem of some kind I would think. It could be pressure as a consequence of bearing wear (clearances too great for required pressure), or it could be cr4p in the oil causing bearing pickup between rod and crank but to avoid it happening again, you need a diagnosis on what happened.

This requires a pro-engine builder to assess ..............

Why don't you give Clark @ JWT a call and email him your photo's ..........

With the much heat in the rod, the crank will be FUBAR as well ........... time to start again with another block I reckon.

Charles' (Phunk) sump is good, but it will have limits and you may have found them. What tyres are you using (how much lateral grip is being generated) ........ are you logging anything (looking for tell-tale pressure fluctuation) ....... there is a diagnosis process you can go thru

This needs a serious review before just building another engine.

It could be dry-sump time - worst case.
