Is anyone currently running a hydraulic roller camshaft in a B/RB engine? What lifters are you running?(Lunati, Comp Cams, ....) Have you had problems?

I have rollers from comp and crane and no problems with them, what are you looking for from them, i wouldn't run a hyd roller on anything serious, and i have solids on hyd roller cams

I appreciate your input. This car will a street driven cruiser. The Comp Cam hydraulic roller (@.050 230/236, ADV 281/287, lift w/1.6 622/625) is fairly mild by most standards. This combined with a Stealth headed 440/512 will make for interesting cruise nights in my 66 Satellite.

You might want more cam with that motor, whats the rest of the set up there, i have one at 500" and i have a 470" with a cam similar to that in a 6pk set up but thats a modified stl head 915 motor vs the 500 which is indy headed

If your really concerned about a good roller use either Crane or Comp. A better choice would be a solid roller.

I just wanted to get a consensus of what people are using in their builds with HR cams. I probably will use the 8921-16 Comp Cams HR lifters.

I use more PBM Pro Series hyd. rollers than anything else. They are made by Morel. I have not had any problems with them and they perform well.

You'll want more cam than [email protected] and you'll want to cnc port those stealth heads. Unported heads, that cam, and that intake and you've got a 600ft/lb 450hp tractor motor......... just an FYI....

Funny, that's how my 440-6 is. 450HP/540tq. The cam is a 485/485 226/234 hyd. grind. It's really just our "restoration grind". It doesn't make power upstairs...it will wind up, but it peaks at HP 5200 on the dyno. On a stroker, it would be 800 rpm less than that. Strokers really eat up a lot of cam.
That small cam in mine thugh, I will say, pulls equally hard in every gear.

And cylinder head/port volume and intake plenum volume..... I did a 4.250 stroke 512-6 with CNC ported RPM heads that went 650hp/685tq with a hydraulic roller cam. It was all done by 6400rpm but that thing was mean....

I agree, with the above posts..
A Hyd. Roller design itself is the "new" fad, but why push away from the proven reliability and performance of a flat tappet configuration? I have heard WAY too many horror stories about the roller lifters going south and taking the better half of your assembly with'em. I say, stick with a mild solid and call it a day. Inexpensive, reliable, and can make plenty of power.

It's funny that the Hyd. Rollers were in Harley engines since the early 70s..and solid rollers since the 30s or 40s in many bikes. Cars are just catching up!
The "problem" with the flat tapped lifters is the oil situation. Just one oil change without zinc fortified oil, or additive, and it's bye-bye lobes!
I agree though, it's hard to beat a solid flat tapper in rpm capability and lifespan if it is used correctly.

Stock appearing is the body, but you can get tons more power with a better cam, if the heads are right.
But if you only want stock perf than keep it the way you have it.
If i was you i'd be in the 280 area at 50
LOSE all the tci crap now... before it bites you hard
For trans and TC in the mopar world you only want A&A or Martin Saine, and you really only want MS for the TC area.

Supershafts,
I appreciate your input. I will tell you this though if I wanted an all out pump gas build I would definately go solid roller. Yes, I have had low nine second street cars and this build is not one of them. Hydraulic roller camshafts seem to be the thing now a days. I want a dependable street cruiser that can get down to business every now and then. The camshaft chosen was researched for subtle sound at idle with deep breathing lift attributes. The cam @ .050 230/236, ADV 281/287, the lift with 1.6 rockers 622/625, lobe center of 109, and lobe separation of 111. The throttle response down low will be great for street cruizing and 3.23 gears. The desktop dyno seems to think the combination will make close to 585hp. I wanted 550-600hp but mainly 600+ft lbs tq. Yes, TCI would not be my first pick for a serious race application but since they hail from my home state and are reasonable at $2100 for trans and converter. I will be dynoing the combination so we can see just how much of a dog she is.

Sweet5ltr,
You know I am not trying to get the purist to convert to hydraulic roller. I am asking for those that run them to step up and let me know what type lifter they are running. It is simple I have done hydraulics, solids, and solid rollers but this build is going to be a HR. Later I will go with another fadish idea which is EFI. Guys, I want a stout street cruiser with good manners and dependability. Just about every new vehicle off the assembly line has hydraulic roller lifters not to mention the further back you the high horsepower factory stuff starting at the end of the 80's. I think that is a little more than a fad. Mainstream HR stuff showed up about the sametime as EFI, just saying.

Hemirunner,
I guess we will find out when I dyno the thing shortly. I will be OK with 550hp but not 450hp. The desktop dyno seems to think around 585hp. Comp Cams seems to think about 550-575hp. The Stealth heads are ported
, thanks.

Do you have a part number for the PBM Pro Series HR lifters? I do not see a part # for big block mopar.

At least it's just a cam and intake change if you don't hit your numbers. We dyno'd a 416SBM with eddy heads and performer air gap intake with a quick fuel 850 carb. We swapped over to the stock intake and carb and lost 90hp...

I really thought something like low to mid 240 duration @ .050 with lift numbers around 600 with 1.6 rockers. You are right if I do not like we will definately change. I know the intake is not the best design and the Eddy RPM would make more power. My vision for when the hood is open will be painted turquoise, no chrome, no aluminum visable, and dual snorkel air cleaner.
