HR 108.0 It looks like new with no wear.The previous owner (aussie) said it made 500rwhp in a n/a stock stroke ls3. Not sure what heads he had and he pulled it out to go boost. I'm going to try this in my ls2/ls7 heads build, but run it as a solid and see what happens. It's very similar specs to the old T-rex but not on xe-r lobes. And I have 1.8 rockers which will bring the lift to around .650/.640 after lash

INTAKE ..

XTREME ENERGY™ LSL HYDRAULIC ROLLERS FOR LS1
The LSL Series has been designed with enhanced characteristics from our latest professional drag racing profiles.

These have excellent ramp quickness but are designed in a way to improve stability over other designs with such short seat timing. The increased lift works well with the latest Gen III and LS cylinder head port designs by providing excellent area above 1/2" valve lift.

EXHAUST ..

XTREME ENERGY™ LXL HYDRAULIC ROLLERS FOR LS1
The LXL Series is based off the popular LSL profiles but are optimized with lower acceleration and a softer closing ramp for less valve train noise and better stability with higher (1.8:1+) ratio rocker arms. These profiles are an excellent choice on the exhaust when used with an LSL intake and perform well for both the intake and exhaust when used in either LS7 or other high ratio applications. These also are a great choice for road race type engines that require extended use at high engine speeds.

I want to make love to that intake port.

If you are running a solid cam don't skimp on lifters.
Buy the best ones you can afford.
Cam motion and another member on here told me the same thing.
Needle bearing lifters can fail suddenly.
Which is why Buy the best ones you can.
If you have the money go bushed.

No the BAM are a very good quality made in USA lifter and gaining a very good reputation for themselves. Lots of hardcore drag racers are using them now even here in OZ. Apparently they are even holding up better than some of the good brand names and even their sizing is more spot on to use with stock lifter bores compared to some other brands. They aren't cheap. 2k to get here in OZ for their best series of lifter which is bushed and pressure fed, but rather than a bronze bushing that wears they have a proprietary steel with coating so it's basically rolling steel on steel with pressurised oil so they last a very long time given if all else in the valve train is as it should be.

Because of the cost over here for bushed lifters and I have seen so many people now that have had the cheaper needle bearing solid lifters just not hold up as long as they'd like with street usage, I have just about decided to keep this LS2 build I'm doing as a hydraulic roller and focus on extracting power elsewhere even single turbo if I want to get serious. Single turbo LS's are turning 8k rpm with hydraulic lifters. Usually running Johnson lifters but some even are still on the oem lifters or oem gm LS7 lifters and turning that rpm.

There's no doubt I prefer a solid roller set up but due to our aussie prices lately and I dislike settling for lesser quality (cheaper) parts, I know I can put that money to better use elsewhere on the car. I might still change my mind and order a set of solid lifters but at this stage that is what I've decided.

Crower is different.
It's the ones from crow I was asking about.
I can't find any info about them at all.

Realised that, just stating the crowers with needle bearings are good due to few comments about needle bearings and bushed lifters.
Crowers are $1300 here in Aus Bortous, Not much talk about the crow solids

I recall reading something in one of my searches but I can't remember now if it was you or someone else. That is my only other thought, I try those and see how they work out as they are currently 1/3rd of the price here on special versus good tie bar solid lifters. And 1/4 of the price of good bushed tie bar solid lifters.

The ones left for sale on the internet is their older stock which are Morels.
