Rollerlifters
 

I know a few had used roller lifters but I'm not shore if Crower or Jesel today make it ( if so special order )
I has seen own made in a bronze bushing with keyslots to Ford FH.
I don't know if Navarro had them in the late 40's (?)
But I'll also seen radial grinded lifters.
I will use std 8BA +40 grams lifters on my Potvin 425 cam but I has another project that can be cool use that roller design ( no racing just fun mechanical stuff )

Ideas on that.

-I seek a 32 core 425 cam, so if anyone has one 'over' I'm ready.

My Ardun had a roller cam in it when I got it. Built in the early 50's. It had 3/4 roller wheel and knocked at the top. They had welded in studs in the block and a piece of angle iron to keep the lifters from turning. I still have it. My plan if I were to use it was to use 1" KB link lifters. 1" body and roller wheel. They fit the block perfectly. I made up one pair with Y-block lifters cut down to fit in the KB lifter with an alum insert to hold them in. That was to get the length right as real Ardun lifters were tall. I never did put much thought into seeing if this would work as flathead, but will work for the Ardun.
