The quote for this engine specifies "4340 Forged 6" H Beam Rods.
What is installed in the engine are clearly I Beam Rods.
This was the engine quote, but as the above shows they don't use the parts they're suppose to.
This was little more than a bait and switch scam. Knowing that the engine's internal parts could not be verified without engine disassembly, I was charged extra for a one-piece main seal block, crank and rear seal but when the engine was opened what was actually installed was less expensive two-piece rear seal.
Plan the build, then build to the plan. If you are careless and don't select comparable parts or double check clearances disaster awaits.
