Anyone running a set of solid roller lifters in there vortex’s i built a little 363 stroker engine for my airboat and have been looking for a knock well tonight I finally pulled the valve covers off of it and I found 2 collapsed lifters so I figured I’d minus will go with solid rollers the hydraulics

You WILL change the cam too, right??

Kurtknarr

was not planning to the sloppy stage 2 works perfect for my set up I was just going to tighten the valve lash down a little more

G Atsma

Solid lifters and hydraulic grinds do NOT work at all,. Ramps are different. Solids NEED to run lash and require an adjustable valve train.

Kurtknarr

yes sir I understand I will have to run the overhead that is perfectly fine buy me the engine is on a airboat so I have all the room in the world

Not true! Guys have run Hydraulic cams using Solid Roller lifters 4 yrs....the Problem is Choosing the Correct material for you cam Core...

👍

Kurtknarr

I will call my cam manufacturer and see if they can help me with this then thank you

G Atsma

Gotcha..... BUT how many guys bother with that?? You or I OF COURSE... but you know..... LOL

Really doesn’t matter with roller cams. Solid roller cams have more aggressive lobes generally, and are harder usually, but you put either lifter on either core. Now with flat tappet cams, totally different story. With a flat tappet cam, you can run a hydraulic lifter on a solid core, but not run a solid lifter on a hydraulic core. Cores are different.

I thought of doing this with my old SBC...

Also with the 408 but after John B ....the hell with a Hydraulic. Martin when he was @ Tick said that's a basic 20+ Hp difference/improvement and my Hydraulic cam was ready to be made..

I also liked those Bushed lifters 🤔

I research everything in sections .... then purchase parts.

Solid roller on hyd cams works excellent. In fact a lot of the cams use the same profiles. Only caveat is that you should call the cam manuf. to make sure because there is a certain few hyd profiles that may not be compatible. But by and large it works nice.

Hyd lifters on solid cam is a no-no however.

Solid is definitely the route I’m going to take does anyone have a brand that they would recommend?

I run Isky solids in my 434. I just looked around for a minute and your not gonna find anything anytime soon…

Jimbo1367

which Isky lifters are you using? Pros or complaints on them?

Im running a set of Red Zone 375RHM solids, with axle oiling, which I don’t think are being made anymore. Needles for me. The bushings have their place, but rob power and if ever put in an application where there is a two-step or a turbo on the line building boost and popping, the bushings get easily damaged. The material is soft. Discussed this at length with Billy Godbold.
I have zero complaints. I heard some talk about the lifter bodies being out of spec, but mine were fine. Darth runs a set of Isky’s with bushings and he loves them so far, as well. I will say that the link bars are big and in the LS blocks, the outer lifter bores (very front of engine and very rear of engine) enclosure tapers off at a downward angle and you should clearance the block there for the link bars…gets very, very close. I didn’t catch this on my build and ended up machining the link bars a tad on the very outer edges. I was able to clearance Darths block in this area while doing block prep work, so his are in the clear for sure. I’m not saying they won’t work, and will hit, but it’s just crazy close, as in .030-.040 close at bottom of travel. Great lifters for sure.

It’s funny how Billy and Nolan have two completely different views of the bushing vs needle subject. I say it doesn’t really matter to anyone building anything here on Tech. Run either you want. But at the same time, I don’t think there’s a more knowledgeable, experienced valvetrain person alive today than Billy Godbold. When Billy speaks, I listen.

Hell I haven't even watched it yet...I saw the thread & posted it . + my 2 cents in the thread.

@ Denny's and it's F'ing Packed damn labor day crowd. I'm trying to get to the boat so I can get some sleep...rant.

Knowledge is Free and gives one things to Consider and or more options from someone who's Profession is Engines. It gets no Better than That.

Pick your weapon from or Based from Knowledge. Not on anything Else. 🤫

Needle bearings Was never a option once I knew that Bushed lifters can take more Spring pressure as well as inform you of Premature issues with the lifters with the sound that's made thru the Bushing.
If you got X amount into The induction ...Y not?
Also the Reason when I was on Some Hydraulic roller 💩 I called Johnson about a Bushed Hydraulic Lifter...

I look @ it as a Pre Warning ⚠️ system to Avoid a catastrophic failure of a lifter...
