Link-bar Lifters - get in here I've got a 408 stroker, going to be running either TFS or PRC 237 heads, custom spec'd cam and of course all the supporting mods.
Question now is, what lifters? I definitely dont want to run LS7 lifters.
I'm really liking the idea of the tie bar lifters for added security and the price seems right.
I'm not looking to spend more than about $425 on a set, and from what I've gathered the Morels are the same as Lunati, and they both seem to get good reviews.
The ones im looking at are the street series for 62-6500RPM's. now I've read plenty of people have gone way beyond that and have been doing fine, however im not going past 6600 period so im thinking these are a great option for the money.
Thoughts? Opinions?

On The Tree
Interested as well. I'm leaning towards the morel street series. I'm going a tad more than 6500, was wondering if they would still be ok. Probably depends on the rest of the valvetrain???

Morel Link-Bar... the 5206 is like $579 most places. Brian Tooley Racing has them for 499. That's about as good as you're going to get.
And I'd stay away from the Street Series. If you're going to spend almost $400 on lifters that aren't anywhere near as robust, might as well spend another $100 and get the real deal.

The only real problem with stock and stock replacement lifters is the inconsistency in bleed down rate. If the plunger to bore clearance is too loose you end up with a lifter that bleeds down to fast it will tick at idle and low engine speeds.
I have some new lifters that you may want to check out. I call them SLR for Slow Leakdown Rate, the ID of the bodies and the OD of the plungers are checked to within 5 millionths of an inch during manufacturing and are mated according to size during assembly. This gives the lifters very slow bleed down rates to avoid the dreaded tick that some other lifters may produce.
I offer these for $199 shipped, I also have the Morel 5290 for $299 and the 5290 for $499 like Jake mentioned.

My morel lifters didnt last long at all in my setup pretty much regrinded the cam and was missing chunks out of every lifter, I had the street series good to 6500, however I run prc 675 springs that have a 471 spring pressure and 160 at open, pretty stoute and I think it was to much for those lifters, I upgraded to lunatis high rpm with the bigger roller, we will see what happens if I have the same issue again or not. but I think on most under 7k applications without crazy spring pressure you will be ok

Brian im REALLY liking yours, especially for the price. I'm about 99.9% sure at this point I'll be running the PRC 237cc heads with PRC .650 springs, stock rockers, and a pat G spec'd cam. will your lifters be able to handle the heavy valves without floating?

Although brian certainly knows his stuff so im honestly leaning more towards his lifters, especially for less money. The main reason I considered the tie bar lifters was to be rid of the buckets but ehh ive never had a problem with them anyway.As far as the TFS im still torn, the prc matches my budget better and it seems like the results between the two can be split between a curly **** hair just about.

In the spintron testing I was involved in, the most startling thing I saw was the difference in net valve lift from cycle to cycle at low engine speeds. One cycle the lift might be the desired .600", the next cycle it might be .500" and the next cycle it might be .450" and the next it might be .600". I used travel limiters in my LS7 lifters to minimize this, but that's just a band aid. Hopefully I'll be doing more spintron testing shortly and I'll have results that I can share.

Whether or not you experience float is going to be more of a function of lobe design and pushrod choice with the parameters given above, with lobe choice having the largest affect. The lifters themselves have little to do with float or loft, but they can have an affect on net valve lift.

The pushrods will be 5/16 .120 wall (or was it .105?)thats the largest the prc heads can accomodate
