lifters

[KST]

Jay what lifter do you recom. for a HS/SB set-up? Don't really want to by Jesels.

[Chris Uratchko]

Kevin,

You don't need 2000+ dollar set of lifters.... A Isky, Crower, or Comp .904 lifter for your engine would work perfectly, for 1/4 the cost.

[Monty Mikho]

Jesel + $2200 / 30 runs = 16 broken lifters and a staff that laughs at you when you tell them about the problem.. Crower has a set of nice lifters (.937 tie bar style) for $650..

[KST]

I had talk to jay a while back and he had said something about running a bigger lifter, just was not sure what was the best and what part number. I'm running crane pro sbf stuff.

[Chris Uratchko]

You can go the keyway style or stick with a tiebar style... but I would go at least .904.... the bigger bearings appear to hold up a LOT longer... over the .842/.875 stuff....

[Jay Allen]

The Isky Red Zone .904's work well. I would bush the block vs just honing the block. But that's me. The Crower lifters are nice pieces as well. Kinda personal preference IMHO.

I agree Kevin. The Jesels just aren't worth the coin to me either.

What is the advantage of bushing the lifter bores? Just curious I see a lot of motors done this way now days.:)

[Chris Uratchko]

Doug,

There is a couple answers for that.

One reason to bush the bore, is to change the location either x,y, or even z(up)... For instance, when you bore the cam tunnel for a 55mm camshaft, the much larger resultant base circle now raises the lifters enough that if a bushing wasn't used the lifter oiling slot could 'sneak' out of the bore...... so simply, the bushing is for fitment reasons...

The other reason is wear. When you get into aggressive profiles, and big pressures, coupled with large offsets etc.... the bores get beat up and you can simply replace the sleeve.... if you have a particular lifter dia, only way to fix a bore is either sleeve it or move up to the next bore size....

Anyhoot... that my piece.

[85Camaro]

Ok I was on the right train of thought then...:lol:

[buschracing]

Kevin, i would go with the Crower .904s with bronze lifter bore bushings. Personal preference. They need slight modification on a belt sander to oil properly on base circle, though...

[Chris Uratchko]

I'll tell ya'll what, and I might get scrutinized for it, but in my personal engine I have been using Comp .904's.... primarily because they are cheap :)

But, I had some very aggressive harmonics on my intake side last year and these suckers are the only thing that came out shining... matter of fact, they went back in this year! :smt119

Yeah yeah... I ain't made of money!

Anyhow my point, is that currently, I feel the larger bearing and housing in the Comp unit makes it a very good lifter....

[steve hurt]

I have used the Crower 903s in past without an issue. They worked great....I have recently switched to Morrell (I think that is correct spelling) and I believe that they are just as good if not better. I know a distributer localy for Morrell if anyone is interested. I was able to buy the offset .903s cheaper than the crowers.....(like by $150) Send me a pm for contact info.

I hope this question is still on track but would lifters of this size be of benefit on a street car? Or would they take a beating at low rpm's i.e idle?

[EloyH]

Jesels are phucking JUNK!!!!!

My first motor they lasted me 20 passes ( new )

My second motor I got a whopping 10 passes (new )

N/A motor making about 1000hp

[Chris Uratchko]

You will likely be contacted by Jesel for this comment.... just so ya know. :-D

[spdracr]

I think he has nothing to worry about with that comment since he has seen the losses. For what it is worth teh last Nascar auction I went to, Crower lifters were selling for under 50 bucks a set and they were not hurt. I do not know what size they were but with a committment, I will carry my Micrometer when I go back again and get a couple of sets. That way you guys do not have to pay marked up prices for parts people are getting dirt cheap. Have other parts may be usefull also but would need up front money contingent on parts being available and as always could not make a promise on being available.

You will likely be contacted by Jesel for this comment.... just so ya know. :-D

[Chris Uratchko]

I would leave the lifters at the auction.... you cannot tell if the axle or needles are degrading from how the feel.... nor can you tell if they have become soft....

There is a lot I want to post about lifters as I've done a competitive analysis on 5 brands now checking assembly tolerances, component tolerances, and hardness of each component... both new and used.

But it would just cause too much grief. All i can say is you see what is in my 9500 + rpm engine with 1200 pound springs and I am not having lifter failures and it is with restricted oiling....

Yes, these lifters all have a life, and I have had expensive to cheap seem to live for about the same length......

Ahhh so much to say but just ain't worth the grief!!!!!!!!!!

Yes Carl, they would.

I could throw a bunch of math at this, but I am not sure it would matter.

The bigger lifter is more stable. The cam acts larger.

I know someone who's working on link bar hyd rollers at .904" diameter that hopefully will be available before the next century.

[O.C White]

Yes they would what, take a beating or be good for a street car? :)

[Jay Allen]

Yes they would what, take a beating or be good for a street car? :)
Well, yes they would take more of a beating. And yes they would be awesome even on a street car.

i just got mine bushed and used the crower lifters,how much oil should feed up threw the pushrod and also should it flow oil no matter where the lifter is in the bore?right now i am finding that the drivers side is oiling alot more than the passengers side.
I did the belt sanding deal with the lifters and am not running a restrictor for them.

Jeff, they should oil the same.

Jay, what kind of time frame on a cam once you get the info?

[Jay Allen]

Jay, what kind of time frame on a cam once you get the info?
I get the build sheet.
The next day (hopefully) it is designed.
Money changes hands.
7-10 business days.

Thanks Kevin.

[KST]

Great, I'm working hard to get you the "correct" info. We are changing a few things and you know good work takes time. Be talking with you soon.
