lifter help??
i need help trying to pick out a set of lifters. my budget for them is going to be around the 300 dollar range. ive been looking at the morel drop ins, johnson slow leakdown drop ins and the comp cam short travel drop ins. anyone have any reviews with these? or have a better lifter to offer? i really do not want to spend 600 plus on lifters right now. little on the rest of my valvetrain setup is. last peice of the puzzle for my build is these stupid lifters! wish brian tooley still made his!

Those PRC springs have too much spring pressure for the YT rockers... I think 420lbs is the most they are designed to take.
As far as lifters, I prefer the link bar. But the Comp short-travel would be better if you can get for $300. The benefits of the short travel at high RPM is worth the time to setup the pushrods with custom lengths.

I am running Morels (don't know part number but they were more than $300). If I were to do it again, I would buy the best Morel with the link bars.
One nice thing about Morel, they can be rebuilt. Most think they will never do this but my original cam had an issue and damaged the rollers on my lifters. I had them rebuilt with new rollers which was significantly less than new.
Just some things to think about.

I agree with Vettenuts, get the Morel 5206 link bar lifters. Also take a look at the BTR TI spring kit, I believe it has less open spring pressure than the PRC kit. You have a lot of money in those heads and valvetrain, why cheep out on the lifters?
I can sadly say that saving money on lifters is very, very expensive. I'm in the process of a multi-thousand dollar rebuild of my LS1 due to Lunati (Morel) cheap (~$350) link bar lifters. Roller pin came out on a start-up and snapped the end off on the up stroke cascading a lot of damage. You have a very high lift cam and getting the valve train stable at high RPM is going to be challenging. I had a less aggressive cam than yours and rev limited at 6,500.
Which Morels? The Lunati and Morel are identical BTW level for level. One of the biggest differences between the higher priced and the cheaper ones are the higher ones are machined steel bodies and the lower end ones are cast bodies. I can attest that the cast ones are brittle. When mine failed and I tapped out one the casing shattered like glass. On the bottom where one got cracked I bent the piece out with my fingers and it cracked off.

I think I'll either go with LS7's or BTR SLR lifters. I haven't read a bad thing about the SLR's yet so I hope I won't trash my motor. I was actually considering the lunati's but after reading svede's case I think I'll pass, plus Brian's customer service is unparalleled.

No, one failure of a lifter that's supposed to be superior in every single way to then be told "oh well sucks to be you" by Lunati customer service. I haven't personally seen any ls7 lifters fail around here in Houston, but either way the BTR SLR's are gonna be go to lifter when the time comes.
