Hey.. man good to hear LS1Tech reaches out the U.S. I am originally from Monterrey NL too. I came to the U.S. when I was 5years old. I have a question that maybe you can answer for me. I am only like 30 minutes away from Reynosa and everytime I go, I see a lot of the 99 and newer chevy trucks with 400SS on them. I am temted to say at least half of them. This is why I am under the immpression they come from the factory with these stickers. What engines do these trucks really have. Did GM realese 400ci vortech in Mexico or these just fake. Gracias paisano.

Hey I saw lots of those new body style SCSB with 400ss when I went to the Bahamas. I was stumped but then I remembered the US is not metric, and these other countries are, so the 400 isn't cubic inches, but something else.

 

I saw them at gm's mexico website and if I remember right they've got the old 350 in them.

 

I am from Mexico as well and when the C/K body style was out I went down there and the 400SS trucks were the equivalent of the "Silverado" trim level here so they had the 5.7.

 

i've heard of gm making a 6.0L back in the day it was a dealer option or something i had a magazine that had one in it and it was the only black one they made maybe i'll look in my magazines and see if i can find it because i've seen it.
