Going to be putting my cam in this weekend I hope, Hydraulic roller engine. What method is used for lubing the cam Journals prior to installation. Engine oil or one of the assembly lubes from Clevite,
Fedaral Mogul, Lubriplate 105 assembly grease,etc
This is my first HR cam so I'm curious what others are using
Thanks

 

Only engine oil must be used on a h-roller cam. Anything else (especially grease) is a very bad idea as it can prevent the rollers from spinning.

 

Probably should have been more clear with my question. Just the cam journals, the lobes I was just going to use engine oil.

 

I am about to do the same-just order new AFR 180 65CC heads and Howards roller cam. I will follow the cam manufacturers instructions.

 

What cam? Make sure to report back on how that works out. Maybe before @ after dyno numbers? I think you have the before runs right?

 

I ordered the one that you and I spoke about-Howards retro roller CL111145-10:

Duration 219/225
Lift .525/.525
LSA 110
Basic Operating range-1,500-5,600 RPM

Yes my baseline dyno runs (2) with the stock L-82 with a Holley 4175 650 CFM vacuum secondary Carb and shorty headers with 2.5 inch duals, no emissions at all is/was 225-233 RWHP. Hoping for 75-80 HP increase.

 

You mean this is not correct:

Sounds like a hot cam spec

 

putting grease of any sort on the journals mite block oil flow to the cam bearing .with the tight clearance ,oil mite be the only thing that stays on the cam journals . presoak your lifters ,and pump them with a push rod to make sure they are full .use a oil primer tool before the dyno pulls start .

 

I'd bet you'll 75rwhp gain.

 

I soaked my hyd. roller lifters in bucket of oil overnight before i installed my Howards retrofit cam. May not of helped much, but it couldnt hurt either.......

 

Now there's something I've never seen before!

 

Thanks, oil it will be on the cam Journals.

 

Yes......just use plenty of engine oil
Nothing else.

 

Well I have to say the roller cam setups are more expensive but they sure remove a lot of anxiety that is required with the use of flat tappet cams on first startups
When done with this build, I'm going to pull the flat tappet cam out of my 427 and install a HR in that.

I just have to get more comfortable with the assembly procedures on the roller cam setups.

Regards

 

Couldn't agree more
Flat lobes are basically a thing of the past! And you can get more aggressive lobe profiles

 

My philosophy is if you want to replace a cam or build a new engine and you can't afford a roller, wait and save your money until you can.

 

After I educated myself a little about the advantages of a roller cam, I would NEVER go back to a flat tappet.

 

My thoughts exacty, Ill probably never use a flat tappet cam again unless there is some compelling reason to put one in. Last summer I put 2 flat tappet cams in both Big Blocks and the anxiety is incredible on start up.

The third and most scary was helping a friend start a 396 in a Camaro this past Fall. He explains to me the motor is brand new built 3yrs ago . Well; off comes the intake, and it was just bone dry in there, you could not see a drop of oil or oil film any where. Out comes the Isky rev lube for the cam lobes, breakin oil just poured on everything related to the valvetrain, reset the lifter preload primed the living crap out the oil system, put the distributor back in around 1 am and decided to start it the next day in the morning.
I could not sleep that night, I thought for sure we would loose the cam.
Poured 2 0z of fuel into the carb, that rascal started right up after 3-4 revolution brought it right up to about 2000rpm, and just played with the thottle for about a 1/2 hour. As far as I'm concerned we got lucky. It has very few miles on it, but all seems good.
