The Crane catalog shows two different LS1 lifters:

10530-16 a For 97-99 engines
144530-16 b For 00-up engines

I understand that they are basically the same, but the 10530-16 is a little stronger. Is this so? Are they interchangeable? Which is more desireable? Differences?

I see the 144530-16 is about $208, and the 10530-16 is $170.

Anyone understand the real differences?

Thanks!

 

I received the following input from Crane tech support:

Crane claims that the block changed in '00 and that the 10530-16 will experience excessive oil loss at the skirt when used in the newer block. Thus reducing oil pressure overall. A very reputable tuner confidently states this is not the case.

I opted to replace the lifters anyway. Even though seemingly no one had any, MTI was able to set me up.
