> You guys throw around LSx and LM7 like its the same thing. Guys are like “yo man I’m a swap a LSx motor in my car for cheap”, but in reality it’s just a heavier LM7. There is nothing wrong with a LM7, just for some cars it’s too heavy.

It’s part of the GM LS series, as is the LQ9/L33/L92/L72 and so on. The weight difference is ~70lbs between the iron and aluminum varieties. Doesn’t seem like a deal breaker to me, but some people might spaz over it.
