"Every time I read about doing this, it makes me want to wear my shoes on the opposite feet. I don’t know why. Even though the right shoe is designed for the right foot and the left shoe is designed for the left foot, I just want to swap them. It works fine and I haven’t fallen, so it must be ok."

There was an old HPP article i believe where a build was done on 400 (it's been 30yrs so it might have been a 455) and they did it and claimed they found power.

Yes you can run solid lifters on a hyd camshaft. They now allowed in stock eliminator. You have to set the lash tight.

You don’t like solid lifters on a hydraulic cam? What about the VMax Rhodes lifters?
|

Rhoades lifters work as advertised but they are nothing like a solid. You adjust them with a feeler gauge to vary the amount the plunger can collapse, but you always have a hydraulic cushion.... We never found a worthwhile advantage to running solid lifters on a hydraulic cam. The hydraulic core using a solid lifter usually looses low end power compared to a flat tappet cam.

Here's a taught; Solids on Intakes, and HYD On Exhaust.

Many of the solid flat tappet cams have more of velocity/acceleration than a hyd flat tappet. It is asking a lot for a Hft with Rhoads V’s to run with a well matched up sft. There are some very tight lash solids and some profiles that are very aggressive that do work ok with a v max. Usually guy’s are doing that to get around class restrict vacuum rules. Mostly mud drag trucks.

I too was thinking of an article that I thought was in HPP;
But either it wasn't that far back, or it got new life being reprinted... because I'm not quite old enought to be familiar with thirty year old articles quite yet.
