Hey guys Im curious; after some bench racing with a buddy, Im curious on the cam/specs you run on Hemi solid rollers for reliable street use?
Mine is a 572 with 11:1 oiling thru the deck with Indy heads and Stage V rollers - our premium pump gas is good here. Just wondering what you've all used specs wise ie: lobes/springs etc are for a lower maintenance street solid roller ?
Thanks !

I'm sure I've told you my cam specs before, but here you go... .672"/.651" lift 276°/284° at .050" 112 LSA Comp 943 springs...225 psi on the seat, 600 psi open. DLI roller rockers. Been using this same setup since 2006. Mild setup that's eally easy on parts, but makes good power.

10.4-1 605 street Hemi. Bullet custom solid roller. .767/.676 288/292@.050 113C. Comp Cams 829 lifters, K-motion K-950 springs 245/720. Rebuilt and blueprinted stock widepad rockers. Engine peak hp is at 5800rpm so the motor doesn't get twisted to high. About 2000 street miles on it no problems so far.Dave
And what did you do to the valve train to make it live I wonder? My little .750 lift cam ate everything...You put enough street miles on that baby, and you will see. I spet $2k refurbing my heads and dropped a little .588 lift cam in. Not happy with the loss in power, but I hit a wall with mine above .650"...

Randy; I'm not saying I won't have a problem, but so far so good. I'll be pulling the motor down in a few weeks to check it over again and to install a geardrive. With minimal V/P clearance and .060 cam lobe to rod clearance I've had a few sleepless nites thinking about the timing chain. Dave

The key to making a HEMI solid roller live on the street is to get oil to the pushrod cups. That's why I always use oil-through-the-pushrod style lifters. I suggest Crane in my book. Use through-the-shaft oiling for the rocker bushings and everything will be happy. Also keeping the lift under .700 (with plenty of coil bind clearance), will keep the springs cool enough.

Rich,
Do you oil thru the intake and exhaust or just the intake? What is your oil pressure drop doing this? Been thinking of going back to a mid .650 roller and this is where I need to know a few things. Do you restrict any oil to the heads when you do that?

I too, would appreciate any info on this subject. I am planning this same kind of street combo soon and would like to have the valve train live.
So how about it Rich, care to spill the beans on this?
Thanks!
Master, again and still

Beans have already been spilled :^) I run the same lifters in both intake and exhaust with Smith Bros thick wall pushrods. I use bronze bushings in the lifter bores with fairly small holes in the bushings (.022 +/-), "white glove" cleaning and assembly, and a low lash cam with street ramp lobes. The effect on the oil pressure is minimal as long as you use a high volume oil pump and good oil (I use Amsoil). I have solid roller HEMIs on the street for thousands of miles and one blown HEMI that has crossed the USA several times The intermediate shaft gear will wear far before valve train issues.
I cannot over emphasize the importance of setting the installed height correctly so the springs never approach coil bind. Most people do not realize that the springs start generating heat well before they bind.
Hope this helps...

Great info guys - Chip yes Ive seen your spex thanx for sharing once again. Rich - I'lll post up my cam/spring combo shortly for your thoughts/comments as to how you see it panning out. I asked the guys at Bullet for the cams lobes not to be too aggressive as the car is primarily a street car which which see some track time. Specs coming....

BTW...I do not have pushrod oiling and don't even have lifter oil galleys in my block (KB). I've freshened the motor up twice since 2006. Put new valve springs on both times just for peace of mind. Sent the lifters back to Isky and they haven't needed a thing yet.
