Tight lash setting solid flat tappet cam

YR, Mine called for 28/32 cold. I run it at 24/28 and have never had an issue.

Are you saying you think I could go tighter that that?


Most likely. I'd start at .020-.022 cold and work with it.

There was a long, very long, nasty thread on speed talk about lash and lash ramps and when you catch the lash ramp. It was very interesting.

It was probably a year ago and I'm not sure the whole thread may have been deleted.

The point was on those cams that call for lash that loose have relatively long lash ramps and you can tighten the lash up quite a bit and just catch the lash ramp closer to the base circle.

Damn, I hope I'm saying that correctly, but I think that's close. Cams with lash ramps that are fairly quick (my cam lashes at .014/.016) don't have nearly the room to work with so you have to be real careful moving from what the cam card calls for either way.
