Money vs Horsepower

The hyd. roller is definitely not the be all , end all ....... but they show a lot of promise in GM stuff. The " if theirs can do it , so can mine " logic applies to a certain extent.
Thelifters are heavier , they are hydraulic and our options are limited with a MoPar.
But this doesn't sound like a spin it to the moon type of issue.
But for what the O.P. is up to , I think it would be a nice choice.
Given budgetary constraints , it doesn't sound like he is after a maximum effort.
Good power and reliability , cruising and occasional track use.
For the average Joe , this can easily be done with shelf parts and with minimum maintenance.
Each step up the performance ladder has a price tag in dollars and effort.
5k a second may sound extreme , but it isn't ridiculous.
Given the LA platform is the weapon of choice here , the inherent constraints in the valve train are already a limiting factor.
You can make them go really fast , but it sure isn't cheap.
