hecho n mexico blocks
- Thread starter 4xfrankie

Pretty sure the Mexican blocks are actually pretty good.
The way things are in the US now, cheaper labor costs plus less environmental restrictions probably make it cheaper to make good blocks down there, than here in the US. If GM was actually trying to make good blocks.
And AFAIK, blocks and many of GM's components come from Mexico, and have for decades.
Now things seem to be shifting to China.

That's Bullshit! No wonder this economy is so bad!As patriotic as I am, I won't use em . My friend was considering using one , and I told him not to . He asked why , and I could not tell him a reason, except they are made in mexico,lol.Pretty sure the Mexican blocks are actually pretty good.

I could be wrong, but for some reason I want to think that for a period of time, all the crate motors being sold were coming out of Mexico.
As much as the government seems to want to bury the fact, higher environmental costs force companies to look elsewhere to make products...I've not seen any specific examples, but it's reality.
We're also our own worst enemy, most of us look at cost before we look at quality. This is why you hear things like "that's just paying for a name" instead of "I'm not willing to pay more money for a high quality workforce that makes better wages, that sells a more refined product, made here".

I can't see much on an internet search about them being junk.Going to go through my old Chevy High Performance magazines and see what I can find .The dude wants to stroke this thing out ,and I think this is a BIG mistake!!
Gm has been making crate motors in Mexico for the last 20 years or more. I had one for many years and miles, no problem. It was also four bolt mains.
Here's an old super chevy article on building a Mexican crate motor http://www.superchevy.com/how-to/46320-gm-350-crate-engine-build/
OK ,after looking through a couple old CHP magazines I finally found something on the subject . There is a section in the back called " ask marlin" ,the resident chevy geek. I geuss it seems that there was a lot of problems in the first couple of years concerning porosity problems with the early target master engines.There was a rumer that in order to fill more casting molds they actually used to mix concrete in with the molten metal as it was poured! This sounds a little far fetched to me , but for some reason , a lot of them were coming back on warranty in the first couple of years. The guy goes on to recommend that in addition to magnafluxing,that a"sonic check" should be performed to find voids inside the block, and to check for core shift. This is something that should be done on a higher performance engine ,anyway.My friend is thinking on AfR heads,High compression,Sollid roller cam, whole nine yards-putting it in a vega. I don't know how much truth there is to these porosity rumors , and if there was that problem I am sure they have been resolved by now , because there are thousands and thousands of these engines built, and are still being built in mexico. Any way, thanks for your replies!
The heads are significantly worse on airflow. In fact the current cheat on GMs new crate engine program is to add Hecto in Mexico to the earlier American cast GM heads and swap them on the 602 crate engine. The blocks are more than likely OK.
I recall an article in an old Hot Rod magazine about searching for a good engine to build up from a salvage yard,having a quote saying "If you come across a block that says "Hench en Mexico" on it,back away as if it were a rattlesnake,and continue your search"..
How true it is those motors were built shoddily I cant say,but I bet that article killed the sale of quite a few engines,that may or may not have had any real issues with integrity...probably a few million produced,and a few thousand failed,so they are "all junk" ?...
