Roller Lifters

[Ziegelsteinfaust]

Yesterday I got my low mileage LT1 350 to swap into my truck to get rid of my pre-ignition issues. After I swap in a new cam to lower dynamic compression.

The 383 LT1 in my truck has the AFR hydra-rev kit. For those of you who don't know what it is. It's a package that puts part of the spring pressure on the lifter body. So the plunger does not start to collapse when you hit 5500 rpm roughly. Among a few other things it can do. Rather or not they matter.

Now we have short travel lifters which supposedly with the right set up can go as high as 8000rpm. Definitely higher then the 6500 powerband my new cam will run.

Is there any benefit to the hydra-rev set up vs reduced travel lifters?

Or was it's whole point before we had reduced travel lifters.
