valve lash for big mp cam?

yeah, stock stall converter. i should have swapped that out while engine was out. just wasn't sure exactly what i should be looking for as far as stall speed.
commando, by mechanical you mean solid lifters? if so, yes.

i sure don't wan to damage the valvetrain, so wider they go.
it's just weird how they have two wildly varying specs for lash...

i'll get out there and report back later. thanks for the tips!
