The big reason is weight I believe. Next up would be saving a block with lifter bores that went south , and though you could simply bush them , I'd look at taking the next step as long as the wallet was open. It gets expensive , though there are some screaming deals on used NASCAR stuff on the bay.........I got a set of lifters for very cheap , but had to send them back because they weren't drilled for pushrod oiling. But they only had " dyno time " according to the ad , and they sure looked and rolled like new. For 250.00 , that was a bargain. Keyway bushings installed is around 800.00 I think , so it do get pricey.

his block has lifter bushing in them now and the small oil holes drilled if i remember correct. so if they are bushed he dont have to use the key way lifter ?? its a world block if the helps

The bushings alone are about $640.... not including installation. To bush a block with keyway bushings is well over $1000 parts/labor. The bushings are made from Ampco 45 bronze which is a very hard material, meaning honing time is greatly increased as well... The last couple we have done, we put block back in CNC after installing the bushings & bored them about .0005" undersized & then honed the last .0005" out to save time/effort.
The installation tool is $2600 from Jesel... very few shops have one, so not alot can do keyways. Jesel does rent the tool, I forget what the rental fee is, it's like $400 for 3 days? & they nail your credit card for like $1200 up front... & $800 gets refunded after tool gets back to Jesel in 1 piece. I rented the tool first block we did, & then after that just bit bullet & bought one.
The lifters are also in the $2600 range for 16 lifters new from Jesel. Most buy them off internet out of a Nascar shop either used or new overstock stuff to save $.

Holy cow! Is that installation tool block specific or can one tool be used on any block?

It's universal.

What's that come to, $100. per gram saved? Only slightly more than using gold for ballast...

I really like my key way lifters, but not the price... We made our own assembly tool, a little cheaper than buying from Jesel Lsm has bushings and lifters that are a little less expensive

How much has that block been decked Ken? 0.200"?
I had a set of Keyway Jesel lifters that I bought at a good price,and then sold too cheaply to a friend who took forever to pay me for them. Unless it's running a Comp Elim or Pro Stock style profile, I would spend my money elsewhere. There are other alternatives to Jesel Keyway lifters nowadays, but they are still kinda pricey. There are some really good drop in lifters available now, so it may be something worth looking at.

Now you guys may begin to understand the real costs of going fast and why real race engines are soooo expensive. These lifters are better in a few ways-not just the weight savings. If you are revving your motor past 9 grand you need this kind of stuff.

Do you mean the side-thrust of dragging the link back and forth?
Keyed lifters are ancient - they just get "re-invented" every 30 years. The expense of machining the bushing looks like overkill. The lifter wants to ride with the roller correctly across the lobe because turning side-ways increases the spring load, so unless the lash gets out of hand the required precision isn't really that high (both angularity and size). It doesn't restrict tappet rotation (i.e., take thrust load) like a pushrod guide actually "steers" the PR, it's only a fence to prevent them from wandering too far. The roller has to rotate a huge amount before it can be trapped cross-wise and self-destruct, and it only needs to be caught before that point - not at .001° off. Harley has used rollers with the wheel captive in a slot for 90 years, and they're pretty sloppy - but nothing ever happens, even in the race motors.
