How far off were the bearings?

Was Plastigage used during assembly? That would have given you a heads-up that something wasn't quite right.

No Sh1t Sherlock, how the Fu*# do you miss that.
What, was it just thrown together without checking any of the clearances.
Makes you wonder what else was missed.

Would have been pretty Friggin obvious there was a problem.
As for the rest of it, just because it held up to a few miles & some dyno runs doesn't mean its been done properly.
Sounds like folks are taking advantage of your naivety.
Imo you need a Better Engine Builder, or this will be just the beginning.
Not trying to bust your balls Mate, just annoyed with the Snake oil salesmen in this industry.
Good luck with it all & I mean that sincerely.

True, it is very hard to get down to the truth of what will hold and what won't. Lots of misinformation out there. One launch at the track and his block is going to crack
between the main studs and head studs. That is why they have a billet block that has been made. That's IF the car makes power. Curious to see what steps have been
taken to deal with head lift. From the pictures posted, I don't see enough.

If all you care about is the end result and not the journey then sure, go crazy, but not everyone shares the same mentality. But can you really call yourself a car enthusiast at that point?

True to a point... but most of those suggesting a professional build have been down that road. We've built engines, trans & rear ends ourselves, learned the expensive mistakes and now choose to use a professional to build our cars. Yes, we could get engines & trans out of a salvage yards, old Detroit muscle was easy to find back in the 70s, now, not so much. Today's cars are sometimes harder to find, when they get crunched, there's not as much sheet metal around the engine and more things get broken.

If someone was building an engine today, my advice would be to have a professional do it, unless you are doing a basic rebuild of an engine that has 200k on it. You still have to have the block tanked, line-bored, decked and the heads gone through. The crank has to be matched to the block and balanced. Not everyone has the tools to assemble an engine properly, ring compressors and good torque wrenches aren't cheap, and why buy them for a 'first-time build'?

Bottomline, your friends' choice. My second piece of advice.... curate the YouTube videos... not everyone has their chit in one bag....
