looking for a high perf solid flat or solid roller that will be max performance utalizing stock type manifolds.
have 10.5 to 1 compression dual plane, 700 double pumper, 4 speed and 3.70 gears. I have componants for a solid roller, if it will last long on the street.

any suggestions?

Small block? Big block? Cubic inches? Weight of car? Street car or strip car?

any suggestions?Solid rollers do not last on the street...and make a huge mess when they go, ask me how I know.

because you probably had one in 1982 when your elcamino was pro street, and used some cheap @$$ components? :)

and solid rollers do last if you are good about it,.

plus i have pressure fed lifters and a rev kit so i'll be fine.

thanks

aaronz28,

Do you mean stock intake and exhaust? No headers?
If you do, I have a 237/243 at .050 solid roller with .566"/.578" gross valve lift, .550"/.560" net lift, that would be about the largest I would run with stock exhaust manifolds. It should be good for about 450 REAL BHP, about 6400. We can make it on 110 or 112 LSA, the wider is better in traffic and for vacuum.
I have not dynoed this in a SBC yet, but am interpolating from my BBC info.
These profiles should be ready by the end of September, as stated by the Operations Manager.

Actually it was in 1997-1999 and they were all Herbert components.

Thanks for talking out your azz again to let us all know you’re still alive.

No, they don't. Solid rollers rely on splash lube, I don't know about you but I drive in commute traffic on the street and the engine spends a lot of time below 2500. There is a reason all the big manufacturers are working on special lube circuits for the rollers....they are tired of hearing complaints about failures.

Actually genious, there are lifters already out there that use high pressure pin oiling, the so called "special lube circutis" that were being researched back in 1997 when you were still in your prime. Now and days it is common practice to use these "special lube circuit" lifters, like the isky red zones/crowers with hippo option. Obviously it isn' t%100 guaranteed but a lot of people are running them with good luck including me. and just so everyone knows me and dennis unfortunately know each other :)

Hi Aaron,
Still playin with that little engine :)
Notice what Harold recommended? Do you remember what I tried to talk you into when you first wanted to go to a roller about a year ago?
I believe it was 234/242 on a 108-109 from memory.

My opinion is you have too much "effective" overlap for your stock exhaust.
Even though you have less overlap by the numbers my feeling is with the roller you have now the actual overlap the engine is "seeing" compared to your old cam is probably hurting you.
Also, given the work you had done on the heads, it could be that improving the low lift flow is actually making it worse.
Yes you can have too much low lift flow. & one of the biggest problems you can have with crappy exhaust is good reverse flow on the intake side on overlap which is usually never checked.
Also, if the cylinder isn't empty when the intake opens guess where the residual exhaust crap is going to go,,
With restricted exhaust you can kill some low lift intake flow or open the intake later & actually make more power & make the engine less "cammy"

Anyway,,, please listen to what Harold is saying here & keep everything else you have as you have the best lifter going.
And, I agree completely with you that there is nothing wrong with solid rollers on the street with good parts.
And, there are a number of members right here with rollers on the street that seem to be doing quite well. but most are not running cheap ones.
There really is a reason these lifters do not sell for $200 :rolleyes:
.
I think you will be pretty happy with the results when you get it sorted out.

======
Dennis,
Most of the big Cam companies are stepping up to a better lifter as they have no choice.
The cams are getting harsher, the springs are over 1000lbs & the older lifters were crashing with regularity.
Unless you consider $2000 Jesels there was nothing short of the Isky & Crowers that were holding up under these conditions for any length of time.
Check out what most lifter bodies were made of & what they were using for rollers. :(

There may be folks working on "lube circuits" for rollers but there have been two outstanding lifters around for a number of years now & you rarely hear of a failure.
One is the Isky Red Zone & the other is the Crower with the pin oiling option.
To the best of my knowledge, no one else has true pressure oiling to the needles regardless of what the ads imply.
And for info the Isky system is patent pending so I think it may be a while before anyone can copy it

I have a number of solid roller engines that have way more miles & or time on them then I would be comfortable with without checking the lifters.
One small block has well over 50,000 for sure & a rat with 15,000 plus now & still counting, probably closer to 20,000 at a guess as I haven't seen the guy for over a year,, & a number of circle track engines with 3 & 4+ seasons on them,,,,

So, in my opinion at least, a quality roller seems to do quite well & I know what my choice is. ;)

I`m not trying to talk **** or take anyones side but don`t "Herbert" lifters have a bad rap? I know a few guys who have run their cams but used someone else`s lifters. I do have one friend who used Herbert lifters with no problems but it was a solid tappet cam. I`ve never used Herbert products personally but I`ve heard that their roller lifters are bad.

Yes, actually they do. Not anymore of a bad rap than Comp, Carne, or Crower early on. Do a search for Comp and see how many complaints show up for cam and lifter failures.

Mike, I know about the priority pin oiling lifters, the Red Zones are still failing at an alarming rate...on the LS1 engine anyways. Nobody seems to be able to build a roller that will last as long as the factory GM part (go figure, the rest of the car falls apart but the lifters last).

well, i have all the best stuff for a roller setup... i'm just concerned that my heads might be hacked up or too big for exhaust manifolds... i really didn't want to pull them and put on a flow bench , but i guess i have no choice.

once i know the flow numbers and low lift info, then we can procede with the correct cam choice.

i really like the cam Harold suggested. i was thinking 232-238 anyway, and this is a tad bigger.

i just want the car to pull like a raped ape from about 2200 on up.

right now, it never really gets out of its own way.

Dennis,
I am confused :confused:
The LS1 has hyd rollers. How does this compare to a Red Zone?

And for a little more unsolicited info,,
Now, this is all information given to me so I have no hands on testing or the actual data but I have no reason to doubt it.

Isky tried the roller assemblies that Crower is or was using which is a very hi end one & they are less expensive but went back to the Torrington's as they appear to hold up better in their testing even though they cost more.
And I believe the Crowers are "crowned" & they say this makes them track better.
The Isky's are not a "crowned" bearing & the reasoning is the "flat" bearing will handle more load due to more contact area.
All I know is Isky is using a bearing that costs them more after a lot of testing & I am reasonably sure if the less expensive bearing assembly had proved itself that is what would be in there if for no other reason than cost concerns.

So far I haven't lost an Isky lifter & that works for me ;)

Mike,

i agree that the cam I have is just too darned big and on too tight a LSA for manifolds... but Ron I. assured me that it would be OK... oh well. He did agree to make it right, once I send him the cam back, he'll check it and see if in fact the cam is right and if it is, then he'll regrind it or send me another, but i'm hearing such good things about the VOODOO stuff that i think i'll just get one of those in the mean time, and when ron sends me a cam back, i'll either set it on the shelf for a future motor, or something.

I was actually thinking like 232-238 at 050 with about 550 lift on a 112 should be good for my car in a street situation... so long as it has a little lope i'll be happy.

thanks

There is a VooDoo solid roller with 231/237 at .050,.555/.566 valve lift, and 112 LSA if you want it. It would be a billet steel cam with the EverWear gear option. They should all be here by Sept 30, or a little earlier.

I run crane solid rollers on the street and never have had a problem. I don't run the cars hard. So maybe thats why. I like em cause you don't have to break the cam in.

Mike, yes the LSX series does come with factory rollers however in the undying quest for more, more, more many have "upgraded" to the Red Zone only to have them fail and go back to factory riollers. No this is not an isolated case or some backyard monkey doing the work. Every case I have discussed has been with a reputable shop that has years of experience with the LSX engines.

Dennis,
You still didn't answer my question :confused:
Are you saying the LSX series is a solid roller engine or are you saying a solid lifter is replacing the factory hyd roller??
Or is this an aftermarket hyd roller you are referring to?
And who are these people that are having these problems as I haven't heard of this anywhere else.
Not doubting you just an inquiring mind,,, & I just don't understand what the difference is in an LS1 that would cause problems not seen in a standard small block??
