Anybody have any experience with these?

Talk to KAAMA or Mr. Gadgets, I believe they might be running them.

Very interesting!

I'm glad someone has designed a better system to keep the lifters aligned without the lousy tie bars in a Mark IV block.

Those are the new style lifters.
Mr Gadgets is running the old style radiused solid lifters that use ceramic instead of a roller.

Now those are cool.
Especially the "oil well" part.

There are indexed roller lifters for bbc's that don't have tie bars... but you have to do machine work to install them.. whereas the tie bar ones "drop right in".

Check out their website www.scubeckracing.com it is a very minor machining process.

Yes Reed, the tie bar lifters just drop in but I've seen WAY too many fail and wipe out the entire motor because of the lousy tie bar design.

I don't run these, but I do run Joe's Radius lifters in my 632. They work awesome! lifters are 1/2 the weight of a roller lifter hence you can run less spring. Oh yeah, they make MORE power than a roller also.
