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?

---

Quote:

---

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.

So you use bronze guides in the lifter bores to restrict the oil flow to the oil thru lifter, correct?...Wonder what that little operation costs. Would not just switching to the oil feed lifters work?

---

Quote:

---

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.

---

Those are very stout springs, no pushrod oiling (right?), and that's a lot of duration and lift for a street engine. Just my two cents..

---

Exactly my concern Rich, yes its thru the deck oiling. Chips cam is similar but with less lift and runs less seat/on the nose pressures.

Interesting in a9seccuda's lift is less, the duration is slightly more yet my springs have way more pressure?

I have a similar setup, bushed lifter bores with no oil holes. How many miles have you put on since 06'?

---

Somewhere around 5-6k miles and around 500 passes down the track. More street than strip time. It's obviously not my daily driver.

Ken Black told me when I ordered this block that when running solid lifters there was no need to have the lifter galleys drilled...even for a street car. Plenty of oil splashing around and draining back down.
Not saying extra oil there would be a bad thing at all, just not sure it is necessary. Maybe in the case of aggressive lobe profiles and/or rockers that don't oil well you'd have to have it.
I'm not being argumenative Rich, you have way more experience w/ this than I do, just repeating what I was told by KB.

Good info - who here then is running into the high 600s/.700" + lift, what springs/oiling/lifter combo are you using and have you had any issues on the street?

I can tell you I never had any issues with my .640 lift roller on the street....My .730 lift was another story though...Keep it under .700. I prefer in the .650 range...

---

Hey Dragula - what springs are you running ie seat/on the nose OD, inst height etc ?

Thanx

just for the record:

solid roller, 248/255 .604/.582 at 112.0 lsa.

that's mild compared to what i've seen here, but still did 712 hp at 6000, and there was a little more there with further tuning.

doubt it's the heads. stage Vs ported by FHO. the intakes flow 435 or so. it's a 540, with about 10.25:1 compression. stage V intake with 2 edelbrocks. there was a little more there in tuning: timing and the A/F could have been tweaked a little. bigger cam would make a big difference...

i know you've posted it many times, but what is your setup?

How many street miles do you have on it? Do you run splash or pressurized lifters? Do you oil through the head (stock) or pushrods? And are you concerned about lifter failure to the point of checking/rebuilding them every few thousand miles as has been suggested on here? Our engines are VERY similar as is the usage (street driven).

Your combo is similar and the springs are similar to mine in seat/open pressures but with less lift on the cam.

My rockers are Stage v and lifters are Isky Red Zone Extreme Roller X.

Hmmm..am I wonder if I am over thinking this despite the spring pressure/thru the deck oiling

Thanks! Where are you guys getting your Stage V rocker setups? Any deals out there, maybe group buys?
