Solid Roller worth it?
We have not run the same miles on the lifters in the engine as the ones that failed yet, so I can't say for sure which one will last longer.

Kurt,
How long did the ones that failed last for???
Did it hurt anything when they did fail??
What lifters is your perferred Lifter to use???
Kyle
The ones that failed lasted around 5000 miles. The car is a powerglide with 4.30 gears, so the highway cruise is brutal on the valvetrain (3200-4000rpm)
It took out the cam on that lobe, and scared up a piston because I kept driving it another 400 miles after it broke.
Jesel without question.

Kurt,
Have you tried Morel's? Any info about them?
What were some signs of a bad lifter? Any noise?
Thanks,
Wes

Ill put Jesel Lifters on my list... since i was looking at Comp's...
Already have there Rockers...
Just waiting on my new heads...
I guess mine wont be as bad with ... a Glide and 3.54's out back...and 28's..
Im around 26-2700 @ 65 mph...

For all out power solid roller is the way to go but what was said earlier is true, if the motor is sub 7000rpm rev'ed (which 99.5% of the street cars you see are) then the gains will be very minimal. The response is a little crisper on a solid roller but not worth the effort if your gonna have to shift at 6600....

Now with Boost......
The lifters usually show signs of going away with lash increase on one cylinder that keeps coming back. Write down what cylinders need to be tightened up when lashing valves if you do it often, and you will see the lash getting loose on a lifter as it goes away. When it finally goes bad it is very noisy, usually starting as a squeal then quickly changing to a cam speed knock.

Kurt, if you guys can't get lifters to last 5,000 miles, what kind of lobes are you guys using?
I guess my question is how did Chevy build solid lifter motors back in the 60's that would last many, many miles?
Does it have to do with the solied ROLLER part? Do the rollers not stand up to the HUGE cams that are usually run with solid lifters?

Were still bushing my lifter bores with my new motor and ill prob try to stay around 74-7500 rpm range tops.....
The higher you spin the motor the harder it is for the stock wet sump setup to keep up.... thats why most switch to dry sump.... and thats another $4500 or so....
The wheel/roller/axle is whats failing in the lifters I am trying. The jesel stuff will last a long time, but we are searching for something less expensive that will get the job done. My car is worst case, and most of our customers will not be as hard as we are on them, but I want to know before we sell them what works and for how long. This will give me guidelines for replacement life on our solid roller engines. At this time we try to steer away from solid rollers in street driven cars, although we have used them in rare cases.

Kurt,
What Jesel PT# are you using??
Kyle
The Morel solid lifters last as long as any of the less expensive lifters.
The lifters we use from Jesel are different part numbers to match the engine they are for. My personal favorite is the .937 body with the .850 wheel on center, but some heads can't work with this.

And what lifters and Rockers did you go with???
How BIG is the cam??
Wow Kurt i looked into the Jesel Lifters.... $1K is alot for lifters LOL
