They have the new patented bearingless roller.mmmmm for high RPM ????? very interesting my dear watson ...

All the better for high spring pressures too.

I have read all about your troubles, you may have enough time to do some research on them. They have come up here for a couple of years. Hope you get back out on the water.

Thanks 2112 , I dont take much time in making decisions i'm an easy SELL if you catch my drift
Theres a local bldr up north who is tight with Isky and surprized he never mentioned these yet .... Tons of guys are using the Morels and on google i've read great reviews...

I would be interested in what he has to say about the Red Zones.

i did some checking on the internet last night myself. read several bbc forums and seems that the morels are the ticket. many have said that they were noisy until warm up. many of the posts on the forums i read through the guys are having to go close to a turn behond 0 lash to guiet them down with out experiencing any problems. there was talk about the variation between alum. VS cast heads in reagards to how much you have to go to quiet them. some post claim they get better after running them for 10 to 15 hours. i realize there is a difference in how much a turn is depending on the stud size but i can't imagine going more than a 1/2 tops. i didn't read anything on the isky's as i was looking more at the morels for myself. dean Gellner had recomended them so that's when i thought i would do a little research myself. i'll bet the isky's are just as good from the way it sounds. i can't honestly say though as i have never used them myself.

I use nothing but the Morels and can not say enough good things about them.

Eddie give me a call when you get an extra 2 mins

If you have the budget, consider the Jessel roller lifters. Much lighter and easier to stabilize/control. Most/all of the Cup teams use them. Options include numerous diameters, wheel sizes, etc
IMHO, your best bet is to select the right engine builder and trust him to pick the best parts package that match your goals and budget. If you think about it, it only cost about $5,000 an engine between average parts and world class parts and maybe another $5,000 between an average engine builder and a world class one.
A really good engine builder will talk you out of taking much risk with his reputation.
Here is what I learned after 5 engine builders. Pick the right shop, agree to the build plan and goals, agree to a budget & time line....step back and stay out

NO budget BIG DAddy , alwayz been told does'nt hurt to ask questions .... been told the rotating assembly does'nt mind the big rpms but the Lifters,pushrods,rockers & springs aint liking over 6000rpm for extended periods of time.... theres a few motors at a Local shop that have pulverized the lifters .... I'm guessing things can get real ugly when you take out a lifter at 6000

Bob, can get you Morel or Isky, He knew about the bearingless bearing before anyone else did. He also did testing on the HI REV Hydraulic before it was ever released. We just set the record straight again on the HI REV Hydraulic, due to some bad information put out there on the Morel's. It's on a thread: HI REV HYDRAULICS LIFTERS & 20 w 50 oil. Better read it before you think all the problems are to blame on the lifters in the set-up of a valve train.
