    lifter change

    I read alot of people changing the lifters out of their ls1 to ls2 or ls7 lifters. is there a reason for this. they are all roller and always thought roller lifters were reusable. unless they are lighter or something and that helps with not bending pushrods and spring life. thanks

    People usually only change lifters if the following happen:

    1: They change to a different camshaft
    2: They change their camshaft and heads
    3: A lifter goes out

    I haven't heard of anyone on this site just changing them to change them. It takes a lot of work (Heads need to be pulled) to change them. If you plan on changing the camshaft or doing any of the following then it is good practice to replace them while you're in the motor

    they are the biggest Men I have ever seen. I
    wouldn't want to fight them!

    Me: That is why no one will remember your name!

    I think the main reason is because you can't buy Ls1 lifters anymore.In 2006 all replacement lifters sold were of the Ls2/7 type.

    there all LS7 lifters now. more durable blend of metal used to construct them.
