It depends on the application and the lobe lift and spring pressure. On the small rollers (under .400ish lobe lift) I use the Morel drop ins and they work great.
On the bigger cams with bigger spring pressure (over 650 pounds open) and big lobes (over .400 lobe lift) you have to really do your homework as most have problems if you don't know what you are doing.
There are several viable middle of the road lifters that work but it totally depends on what you are doing.
The high end lifters usually require block modifications but can accomodate much more spring pressure and lobe lift. The price though is now at least triple what the others are.

In the .420ish range if the nose of the lobes is right out at the journal diameter the morels will still work. If it's reduced base circle you would probably have to go to the Comp or Crower. The new current Comp LS1 solid roller lifter is decent and works without issues but the older ones do not work. The Crower is nice but may hang up on the block if you have a reduced base circle even at .420 but otherwise should work fine.

Maybe it is just me, but seems like there is quite a concern on lifter issue's with the LSx series? While yet it appears to be the only one (unless you count the hardcore guys that want the 5th head bolt) it seems to be really the only concern in reliablilty with this motor. Now, again as some know, I am new to to the LSx scene, but I have already read quite a few threads on people having problems with lifters with this motor. Coming from the Ford camp, and forums over there, you never talked about lifters being a problem. Hey Erik, am I speculating here, or is there some truth/fact behind what I am saying? If so, do you have any theories on why this maybe? Is it because of the tray? Is there just an oiling problem? Poor design? If you were putting a solid roller motor together, cam in the 260/.700 range, what lifter would you suggest? You can PM me if you like

The LS1 is made like the Cleveland and so the lifters must be made like that too and most aren't so they don't work. Some have been fixed over the last 5 years and some haven't and many of the older non fuctional ones are still out there. I have had to fix maybe 20 of these "engine builds" and the fact is that the average "machine shop" that builds engines has little to no knowledge about anything until something bad happens and then the sh&t hits the fan.
Unfortunately the lifter company's engineers are usually totally clueless as evidenced by the huge number of lifters that are made wrong or don't work at any real lobe lifts. I did the first real working solid roller setup years and years ago at SAM with Jud and I called Ron Iskendarian and I just went through the catalogue and found what worked and Isky customzied it with Ford tie bars and different oiling holes and still 7 or 8 years later these guys can't make half their sh&t right!

What about the comp 8950 lifters?
Oh, the PR length is 8.100 so im guessing its a reduced base circle.

Cool, thanks Erik! This site has been a great place to pick up some info that I had NO idea on about the LSx, like the lifters here. And that is why I am also having my first LSx built. It's what I did with my Ford stuff: had first one built, learned some stuff, and then dove in and built all my other motors after that. I know what I CAN do and what I CAN'T do. I know my fair share, but don't know it all either.
Going to try and head up to USA today and talk with the guys about the lifters and such, and see what they have to say. Thanks a bunch (again) Erik
