Quote: Who makes the HR lifters Hughes is selling for $365/set? I have been using them in the 505 stroker with a Comp XR286HR-10 cam. This engine was the first HR cam big block for me, but it seems to be running OK. When I raced the car, I shifted when the car hit the 6,000 RPM rev-limiter (no tach.)
I use the same lifters in a 505 stroker and a hotter cam from Hughes and they seem to work great so far but spring presiure cant go over 380 on full lift and seat load 180 ! I whas told that these are some kind of good street roller lifters.
