Crate 360 vs DIY Built

I had good advice from my engine builder: The Iron of today isn't the iron from "The Day". he says the new engine stuff is mostly recycled Iron, and the second time around it isn't nearly as good. I always try to rebuild a good original block, then I feel I have something. I had a crate Hemi back in 2004 From Chrysler, and it was a piece of junk. I had to literally rebuild it in order to run it. It wasn't bored properly, and had the wrong rod bearings in it, right out of the crate. To add Insult to Injury, my machinist said:
That looks like a Chevy engine, with Indy parts. it doesn't look like the original he has from 1966 in the back room. I sold it and went back to the Original 440HP.(GTX)
Someday i'll find an original 66-71 and do it again. But to this day I don't trust crate engines, or the people that build them.:happy1:
