Looking for some opinions. ..
I bought the cheap Morel Solid Roller lifters part number 5452.
I'm going for a max effort build on a grudge race car.

Should I go with larger body lifters and machine the block for better tolerances? Or even possibly bronze lifter guides?

Had a company tell me the Morel 5452 are good to go and had a local builder tell me to machine the lifter bores.

Thanks for any advice.

 

You could step up to the morel ultra pro tie bar lifters like I am running without machining the block. The ultra pro required a lot longer push rod though then I anticipated. I have heard good things about the 5452 like you have.

 

Well if this is max lift /compression E-Z roller bearing LESS LIFTER is the best on the market the Bigger the LIFTER the better.... if cash is no problem. the link-bar lifter is better also.

 

I bought the 5452 because I was trying to save a dollar but I realized I rather do it right the first time. The lift is in the 700 for the cam I am running and about 12:1 compression. If that makes a huge difference.

 

well i got something like yours LQ9 stroker eagle rod/crank upper 11':8s compression Mars@ Tick soiid roller and the 1 thing I REFUSE 2 See was a damn lifter bearing cost me a engine I always wanted...700fwhp from a pumpgas street motor with a/c.
They have a few good lifters but with only .700 that should not be any problem
hit Mr. Tooley for your springs he will tell you what else 2 get 2 have that baby Purrrring like a.......LION...lol.

 

I have used the Morel .842 and .903 lifters with success.

6132 for the .903 and 6130 for the .842.

Those are both bushing style lifters.

 

Jesel keyed lifter is "max effort".

 

You need to be a little more specific about your build. The lifters you have are good for a moderate solid roller 7500 rpm or less. If you intend on using aggressive lobes and or high lift then you should look at a better lifter. How much better will depend on what you're doing. If you want 9k+ rpm drag engine then you need a .937 or 1.062 Jesel, LSM, Morel, or Isky EZ Roll. If you have an endurance application I'd run Jesel, LSM, or Morel needle bearing lifters.

 

I make simple for my self, can't tell you what to do but I can tell what I do,
I use heavy duty drop in comp cams pro elites, take a close look at these.

Among the details I like on these is they are super light only 96 grams completely polished so at high speed the lateral loads will not cause the lifter to attack the bore, and reduce spring capacity or cause valve train to destabilize.
Huge axel and bearing are direct oil fed and incredibly strong, plus the needle bearings are not visible and are completely enclosed in, axel and needle bearings are completely polished.

Those I call them drop in, don't call anything drop in unless I find it completely worthy.

The picture you'll see is not the correct representation but they have the real McCoy on sale.

A lot less than I paid for mines.

And now the real picture..

On some sites it suggests the bushed style lifter needs inspected every 1500 miles ?

Is that correct ?

Is the bush on the roller as opposed to needles ?

For a street car with solid roller, which would be the best option ?

 

They are finicky to oil contaminates. The needle bearing would be a better option for a street car.
