Hydraulic roller lifters
 

whose are the best ?? bbc app

I think most everyone would agree that at this time the Morel lifters are the best bet.

rmbuilder aka Bob Madara of Marine Kinetics has very good pricing for lifters manufactured by Morel. 585-654-8583

Morel, Morel, or Morel.

I also sell them.

I used morel lifters in my motors, they are a nice piece not like cranes.

cafe,
If you decide to go with the Morel's, email me and I will give you a pretty good price.

I have two sets in my 502s and they work great but they make a lot of noise when cold.I have adjusted them a few times to try and get them quit but for the first minute or so they tap away and then the rest of the day they are quit.Any ideas if maybe something is wrong or is this common for the morels?Motors only have about 70 hrs on them.

Thanks Anthony

We have not touched our valve train on our Ice Injection test engines.

We now have 220 hrs spinning up to 6600 rpms on most every test run.

This is with 93 pump gas & methanol injected 565s 14 -71 high helix 14 honest lbs of boost using "Crane hydraulic lifters" and quite high spring pressure.

We hope to see 300hrs with out a tear down of any kind.

As we still leak down 9% cold.

We have had great luck with Crane lifters on these high rpm big power hydraulic applications!

Anthony,
I have not had any reports of them being noisy. I would look for something else being the cause. What oil filters are you using ? Some of the "less expensive" ones do not have the proper anti drainback valves and will cause the same problem.

Is there two different model numbers for a mark 4 and a gen 5 block?Both motors were freshened and I wonder if the motor guys mixed them up if they are different?

Anthony

Anthony,
There are two different ones, but the difference is that one uses a link bar to hold the two lifters and keep them from rotating, the other uses the stock GM "dog bone" You can use the link bar type in the late model blocks, but not vice versa. Either way, that would not explain the noise on start up. It sounds like the oil is draining out of the oil galleys when the engine is sitting (which is somewhat normal) or for some reason oil pressure is taking a while to build up when you first start them. Next time you start up after sitting a while, watch the oil pressure gauges. The lifter noise really should disappear as soon as oil pressure is up to normal, usually within a few seconds of startup.

I have to ask would you be more specific on what (quite high spring pressure) is? How big is the cam and is it also a crane or special grind. Your way over my HP goals so more curious on ramps than actual number for the cam. Impressive builds for sure. :ernaehrung004:
