Thats for a road motor that I expect to last 50K miles or more, its different if its for a race application.
I was hoping for a reply from you, as i remember reading your Nova thread, how's it going by the way?
Sounds like a fairly old fashioned way you used and pretty much my second method.
However, how likely am i to do 50k miles in the car, (not very). I'm tempted on a race style.
I'm sure you've seen this, not sure how much truth is in it.
