Re: HR cam w/ SR lifters pro's & cons

I sure wish VortecPro would explain why you need a BIG oil pan with those lifters. I have been running them for since 2013 with a stock oil pan, with no issues. Maybe Chris Straub could explain the issue? I hate to think I am hurting the engine.

Here's my VotecPro 467

4.310 x 4.00, 9.7 compression, 781 ovalport GM heads ported 2.190/1.880, reproduction GM low rise LS6 intake manifold, 780 CFM factory LS6 carb. 228/238/.553/.578/111/106 Hyd roller, solid roller lifters lashed @ .010/.012. Modified GM 4 quart oil pan, M77 oil pump. Tested on 91 octane gas. Maxima 10/40 oil. 560 HP @ 5800 RPM, 588 TQ @ 4000 RPM.

The solid lifters are going to make the cam numbers a little smaller due to lash.

You can go to the VortecPro YouTube channel and compare the various 467 builds with similar cam and hyd lifters.


There are minor variations in various details but solid lifters didn't appear to cost me too much power wise. My intake and carb lost a bunch of hp for sure, so take that in consideration too. Granted, Mark designed the build with the solid lifters in mind so he could adjust for them. Not sure exactly what it would be if you only changed the lifters?

Others can chime in but it seems nominal for solid lifters only.

What happens to any hydraulic functioning system if it get air in it? Aeration of oil is not good for bearings or hyd roller lifters.

Absolutely, we documented it three days apart, near identical weather conditions, no change but the lifters. Going from hydraulic rollers (verified with both Crane and Morel, two different motors) to solid rollers on hyd roller cams ("0" lashed dead cold) both cars picked up 2-3 mph. Conclusion was had to be bleed off due to aeration.

Wow. Air sucks as a lube or pneumatic media.

Thank you for repsonding Chris... how is that different from any hydraulic lifter? Does that mean I need an 8 qt oil pan? Different lifter?

No difference. Aeration of any hydraulic system will not allow it to function correctly. This affects all lifter brands.

Re: HR cam w/ SR lifters pro's & cons

I hope to soon start clocking my 12 yrs + Jesse! I'm curious as to what oil the pro builder recommends. ( I do have 3 cases of VR1 10-30)

Not much if any under 7000 rpm IMO

I knew after that first night with the 9.82 we would be going back to hydraulic lifters.

Re: HR cam w/ SR lifters pro's & cons

I've seen oil aeration effect my combo.

One night near the end of the night after many passes it just blew the tires off so I zoomed down there didn't shut the car off did a hot lap pass time was ok for a soft leave and almost 200 degree water when I staged it.


I pulled my helmet off and pull up to get my slip and hear very loud tapping and clacking undrivable nasty sounding .I thought I broke a valve spring.

Great! turn if off and coasted into the grass pop the hood let it cool down and walk down to the burger stand grab a drink sit down and watch the last of the cars and Contemplate life's choices.

I'm by myself on a Wednesday night its heading toward 11pm all my friends live an hour away that have trailers and they have to work the next day.

So its Fix it ,drive home on 7 time or IDK $400.00 tow bill??
The track is out in no mans land and I live about 40 miles away. I'm sure that charge extra for midnight calls

I carry a load of tools and a lot of spare parts like extra rocker arms and poly locks etc...

Fire it up to determine what valve cover to pull. Quiet now yup it fixed itself. Pulled dipstick could see some bubbles.

If I had a cheaper oil pan the problem would have only been worse
and I want to say after installing a vacuum pump I haven't had an issue since.

Iron heads/iron block I would use 0.006"/0.008" cold, no more.
