Just wondering who made them if they do at all.

 

I've yet to see fast bleed rollers from any of the majors, like Comp, Crane, Crower, etc.

Maybe some day?

 

It seems to be an idea whose time has come and gone, since it doesn't really satisfy the customer.

When they first came out back around 1980 or so, I was caused by customer insistence to use them in a couple of motors I built for people. In every single case, the customer paid either me or someone else to remove them, within 5000 miles, and in one case I can recall, to install a more properly selected cam for the rest of their car's combo. I'm fairly sure it wasn't because they enjoyed them so much.

Crane and others still offer such things in flat-tappet configuration; but I think that's all. No rollers.

I've never used them in one of my own motors. I've always actually just bought the correct cam in the first place, and not tried to "cheat" on that, over-camming a motor and trying to minimize the side effects. I guess they're one of those things that looks good on paper but comes up short in the real world.

 

I just wanted to find out if they had rollers or not and follow that with a price. I wouldn't mind experimenting with them.

do these things actually work?

 

supposedly. My uncle ran them in his 68 camaro and loved them.
