    For those that are running LS engines, what are you running and why did you decide on that engine? I don't know the difference between all the different designations, ie LS2, LS6, LQ4 . I know the LS1 is an aluminum block 5.7L , other than that I'm not sure. I am trying to plan out my swap, any and all help and info is much appreciated.

    I don't have one......yet. But my opinion is, if you're going to go through all the trouble of an ls-series swap, why would you get a little one when you can get the bigger one for the same price that'll have better potential for power?

    I went with the 6.0, although I'm not finished yet. The deciding factor was that I found a cheap wrecked 2001 suburban 2500.

    I feel the same way on the bigger displacement. I am pretty sure I am going with an iron block 6.0L. I just wan to see what opinions are out there to see if someone changes my mind. I'd love to go 6.2L but they don't seem to be real cheap.

    Unless you can get a 6.0 for cheap, you might as well get an aluminum LS1. They are going to be around the same price as the 6.0, and you will save around 100 lbs. with the aluminum block. And the .3 liters won't make that much of a difference.

    I'm going twin turbo so I want the iron block for the strength.

    If your going turbo a 5.3 will be fine. All motor go 6.0 it's cheaper than a ls1 I got mine for 900 and can be found all day for 9-1300 the 6.0 has the bigger 4inch bore needed to run the bigger heads with the big valves

    5.3= 3.78 bore ls1=3.89 6.0=4.00. L92 heads need a minimum 4.00 bore

    I you are going turbo, 5.3 will be good. They can and usually are bored to accept the 5.7 piston as there are many more choices in that diameter.

    I was originally looking for a 5.3 for my turbo build but, I found a deal on a LQ4 6 liter complete take out. Bigger turbo now needed!

    They do make an aluminum 6.0

    That said, my rule of thumb is to get the most displacement you can afford. They will all take boost, there is a large selection of aftermarket parts for all of them, and really you can't go wrong with any of them either
