Lifter surprise???? GM offered two types of lifers in the LSX series motors, the first one was installed in the LS1 motors starting in 97 and ended in 2000. These lifters were a split/non-encapsulated type of lifter that most builders believed were not very durable for hig HP motors. The second type of lifter was a fully encapsulated type; meaning the roller was mostly surrounded by the lifter itself. These are considered the most durable and have been used in motors with high lift and HP figures well above 1200 HP.
So today I'm tearing apart my 2004 LS6 motor and guess what? It has the older type of lifter installed!!! WTF?? Anyone else have this issue?
This is my third LSX motor and the first one I've seen with this.
So now I'm thinking I have to purchase a set of new lifters...................

Same here just finished taking my 2002 LS1 apart and it had the split/non-encapsulated type of lifter. The builder that I am working with told me that he sees this all the time. It is hit or miss as to which one you get.

Sounds like the non-encapsulated ones would be lighter. May be the newest design, although when I ordered, lifter - 17122490, from a local dealer, I got the encapsulated one for about $35.

The melling lifters are an encapsulated design, and they run about 14 each at the local auto parts store, or 165 for the set of 16 through futral. From what I understand futral uses these even on their big hyd roller stroker motors, so I would think it would be a quality part. They look pretty good to me.

Youre right, the encapsulated lifter are pricey from GM. From a dealer expect to pay $35 plus as Dipstick stated. While the non-encapsulated type is indeed lighter is not what you want in a high HP LS motor. They are just not built to withstand the demands of high loads for a long period of time. If you cruise around town and have the occasional greeen light run, youre fine on a low mileage ride.
I would definetly go with the Mellings or other encapsulated types in any other ssituation.
