I don't know anyone offhand that runs these. Duane runs stock sawblades with slicks on them...
PS: Don't worry about 'violations' - we're pretty relaxed about this, as long as you aren't posting pics of XXX footage. You'd have to link to that. :)
Change your thermostat.
Milky oil only happens in very bad cases of BHG - the oil passages on the head gasket are much further away from the cylinders than the water jackets.
It's been done, although rarely. If you are going to fully balance it, might as well do this as well.
While you are at it, think about adding a crank scraper as well...
As for the speedo, that likely means the speedo cable is disconnected somewhere - either behind the dash, at the tranny, or at the halfway point where the two parts connect.
Actually, I don't really know that much about it. The rev limit was dropped with the heavier crank, but the reason behind it really is a guess on our part - more rotational mass means it't tougher to spin up and down in speed.
It should be several extra pounds, as the 7M has 2 extra...
A bunch of folks here swear by the permetex brake quiet spray treatment. Just spray your head gasket before putting it onto an unprepped block and pray. :)
