I know the LS2 started in 2006 but just curious if anyone knows what year the "improved" lifter design started in.


Just picked up a 05 L33 engine- didnt know if I needed to upgrade the lifters while I had the heads off.



Thanks

 

Get some LS7 lifters and call it a day.

 

LS7 lifter is probably the best bang for the buck. Get new lifter trays too.
