Obviously your engine builder knows more as they have the bits, but when the engine was first build I'd hope it was bored to suit the new pistons?
So any used block that still runs should also be suitable to take to the first overbore size. Unless someone just honed it and fitted stock size pistons
I’m not sure if I’m honest but considering the reputation of the company that built it I wouldn’t be surprised. (I didn’t know about the reputation when buying the car) It looks like it was a tolerance issue that caused it to fail.
Before putting it back on the road you'll need new wheel bearings. The weight of the car will have shagged yours as the shafts aren't in
Looks spot on though. The soda blasted parts look minty
Thanks I’ll add those to the list! Haha. They’re probably past their best anyway. It really does transform the parts.
