    LS2 vs. LQ4

    I never hear of anyone swapping to an LS2. Why is that?
    Name: Mark,
    God created turbo lag so nitrous trucks could have a chance.

    Reluctor wheels and Pain in the but wiring + cost. Add heads and cam to a nice LQ4 and you get just as much if not more power than a stock LS2. Aluminum block is the only thing I think is interesting about the LS2 but the weight savings is not worth the cost. I could be wrong, but I think I am mostly right.

    I think it is mostly the expense. You can buy LQ4's for about 1/8th the price of an LS2.

    LS1/LS2/LS6 = bad idea on 5000lb monsters...if you put the power to it that is!! You have a much higher chance of warping or cracking the block with that kind of load

    If you can crack an iron block then im sure aluminum won't be any better as far as strength goes.
    anyone ever crack an iron block cyl wall? well i did - PerformanceTrucks.net Forums

    Plus if you go to LS1tech.com and type in cracked aluminum block in the search, you'll find many MANY people with cracked block posted up there. And they are ls1 cars. Too much power can crack any block, but an aluminum block with 5000lbs load on it will crack much easier than an iron block

    reason is why you dont see many swapping them is the cost
    Please my friend, im not trying to be an ass but i think i know a slight bit more about these motors since i have a custom built 383 that was garage built but machined through LME

    Not trying to be offensive here just stating what ive learned from being in the game for the past 6 years now EXTENSIVELY

    Nick,Here are the final Pics... - PerformanceTrucks.net Forums

    I know about puting power down trust me!! Im not saying the blocks are crap so dont take me wrong, I merely said with ALOT of power, your chance of ceacking an "ALUMINUM" block is much higher than cracking an "IRON" block. <<<If that statement isnt true then show me how you figure that an aluminum is stronger than the iron

    I can see you just like to talk to start !*#!

    "I never hear of anyone swapping to an LS2. Why is that?" <<Is the original question.

    How does my answer not have anything to do with this question.

    Guys with ex cab trucks, perfer 6.0 block to LSx blocks for a couple reasons. Some have been mentioned "I think it is mostly the expense. You can buy LQ4's for about 1/8th the price of an LS2."

    What was not mentioned and is not ALWAYS the reason to not buy it, since not everyone plans on puting enough power through the motor to crack it, is that aluminum blocks crack EASIER<<Keyword here, than an IRON block
