Thanks very much!

 

I have asked him about lunati lifters vs ls7's, comps...etc and he recommended the lunati. However, he is a sales person so.....you know. And I'm a big fan of impartial opinions, and I hate when I call certain vendors on here and ask a simple question and I'm repeatadly tried to Be sold something...

That's why I'm asking here about reasons to use the more expensive lunati lifters over the tried and true ls7's.

 

That's a reasonable approach. In my case the deciding factor is the difference between Made in Mexico (LS7) vs. Made in USA (Morel/Lunati).

 

.010 to .020 is the preload he recommends. He said everyone has trouble setting them up for some reason. I'm assuming because of the short travel design.

 

Short travel lifters are very hard to work with if you don't have an adjustable rocker for sure. The main difference on the true Morel lifters to me are a more robust build quality as far as if abuse does happen. All lifters can turn fairly high rpm with good valvetrain but if you get some float or over revs etc. the Morel body and wheel and axles etc. can take a lot more beating if it happens for whatever reason.

 

Good info, thanks for posting it. I'm right in range, measured 8-3/4 turns to zero lash on the Comp measuring tool and installed 7.250" pushrods.

 

That's what I used when I set up the street lifers in my motor.
I've ran the street lifters in my motor with ls3 heads with 621 lift and now with some ls7 head and a 66+ lift cam and haven't had any issues to date. And the motor is shifted at 7000 all the time. the lifters do not like pre loading at all.

 

That pre load spec is for The 72532's...not the streets.

 

I just got my 72332 street link-bars and the pre-load spec is .045-.050 for alum block/alum heads

 

So I would assume .035 to .040 for cast iron block/aluminum heads?

.030-.035 for iron/alum

 

Any updates on the street lifters from Lunati or Morel?

 

Bringing back the dead again....... in the market for some link bar lifters to spin 7K+ I see most of the posts and info in this thread are 4-5 years old. Does anyone have some recent experience with the Lunati 72332 or Morel 5290 lifters?

 

I'm running the 5290's with 460# of valve spring pressure, 680 lift, and spin it to 7200. Only have around 1000 miles on it or so. But holding up so far.

 

I'll be using the Johnson SLRL for my setup. I've heard great things about them and they were recommended by Mr. Tooley and company.
