Correct initial timing?

This is the old-school Direct Connection "Mini-Express" mushroom lifter setup "comes very close to roller cam performance at about half the cost". Originally 316 advertised, [email protected] measured at the cam grinder's, .654" lift with .024/.028 lash. Centerline 107.
I had to have it slightly reground because some of the lobes had lost their taper and wouldn't spin the lifters. It came back as 312 advertised, [email protected], .652" lift with .018/.018 lash. That is actually a slightly faster rate and more net lift :) I put it in at 105.
What website? Hope it's not YB :poke:


No, not YB LOL. I'll post the page when I get a chance. You can't type in all your specs and it shows your lobes and gives all the numbers and such. I *THINK* 12many posted the site in a different thread.

Damn I'm jealous. I should have done the mushroom lifter deal on my last build.

In your case, a 1200 RPM is pretty dang spanky. I've never been bothered by idle RPM. I've had cams back in the day that if you can get a 1500 RPM idle you'd be doing good.
