Has anyone done this yet? flat tappet not roller.

[Mark G]

Yep Solid roller lifters lash 0.006 hyd roller cam

Yes we have a few times. Kind of pointless

"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."

It was that...

[slowbird]

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.

I was thinking of that one too.
IIRC it was Bill Ceralli, 455 or maybe 433?, made 530 peak hp. Good numbers for 30yrs ago with nothing exotic. Don’t remember much else..
...like wedding anniversaries...

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.

Can i ask why?

[joes455]

Ran solids on a mellin sp8 12.2 1/4 mile 112 mph

[unruhjonny]

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.
