No, since factory lash is HOT... so it would be loose when cold,

ran it 20 minutes @ 2000 rpm and given lash of .022 wich as you say with engine hot and running was .020... then I took it for a ride and adjusted ex .45 mm intake .40 mm on the loose side. Tested another setting first with .40mm and .30mm in ex

We're saying the same thing but in opposite ways. An adjustment made cold, tightens up when it heats up. An adjustment made hot, loosens up when it cools down.

Whah! You're mixing thousandths of inches, with millimetres!

1" = 25.4mm

Hey Cstryker, did you hook a vac gage? I'm getting steady 18-19 idling @ 800 rpm and around 15 when sitting on a red light brakes on and trans in D. Even given the "low" vac readings, it has plenty of guts before the advertised peak torque... the torque band feels way more stable than the original cam or the MP244 or others I've tried. Stall is stock and gearing is 3.07
The effect I'm seeing in my buddy's car is that when you go off-line with medium-light acceleration, instead of dropping a lot and then as it revs up going up, the vacuum stays kinda in the sme place... and going up.
