Technical solid roller lifters with pics

i cant find any info on these solid roller lifters. made by morel and they are for sbc. they have a flat machined side to them and a flat plate that sits in the lifter bore that keeps them from turning. they have a part number that is csbv8. looks like an interesting design. what do you fellas think? thanks in advance.

I wonder how long that plate will last? Yes interesting design, I am just wondering about the life of that plate that keeps them from spinning.

 

Morel still make lifters,but not in that style it seems. I'd guess that it was not successful .

 

would that little plate not make some grooves in the walls on the block?

 

thanks for the replies. that plate is a very tight fit in the block. so it should stay put but for how long is the question. has anyone else ever see this design? thanks

 

it has a patent, from 1990. by a guy named Morel.
