differences in LS1s?

  1. Never listen to the LT1 haters, they have all been shown the 2 color tail lights :wink:

  2. 98s also have a smaller oil passage in the rear of the block which was changed at some point after 98 (99, 00?)

  3. 01-02 cars occasionally got LS6 blocks (improved oil passages being the main difference). They also had LS6 intakes with no EGR (obviously)

  4. 98s are also the last year for metal gas tanks + diff. pickup setup ( :tup: ) , and their guages were true…aka 99+ the coolant guage is bullshit and the other displays all get their info from the computer itself

If you can get a 98 for thousands less, it can make sense to. The biggest draw back when modding one is the computer, just bc it is slighty more limited and less people have the software for them. Just like LT1s though, any year is a good platform and can be made fast as shit
