Does your Futral Cam clatter like a sewing machine? I know most of the aggressive ramp cams clatter but there are some that are perfectly quiet also. With the Futral ramps being slightly less aggressive than the X-ER's out there, I'm curious what percentage of the Futrals are quiet. Especially interested in the F10,F11 and F13.

I have a CompCam on XER lobes that has almost the exact specs of the F13 and a buddy of mine has an actual F14. We have tried to compare valve train noise before, but we both agreed that it is all pretty much the same at that range of cam size...

OK We have 4 sewing machines, 2 that are quiet and 1 *******?? 
so far. I thought I may find a trend that people with milled heads had clatter because of valve train geometry but looking at the sigs so far, I don't see any trends at all. Are all of you (clatter and non clatter) using 7.40 pushrods?

Adjustable rockers will quiet things down, because you can dial in the lifter preload.
On non adjustables try to run 7.425 p-rods, it will quiet things down a bit. (Did with mine, XE-R .581 lifts)

So far it looks like we're at 8 sewing machines, 3 quiet, 3 blowers and 1 tittie
