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"...

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 !

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?

So how about it Rich, care to spill the beans on this?

Thanks!

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...

My 572 is 10.5-1.
Comp cams
.421 lobe lift
Stage V rockers
.674 I .657 E
264* 270* @ .050
112 LSA

Lifters have Oil fed rollers, but not push-rod oiling.
Smith Bros PRs
Comp 943 springs
World alum block comes bushed with oil hole.

I do not have a lot of street miles on the engine yet, and only a few passes 1/8th mile.
