build it to last big block guys

If you are talking about the basics...I think pretty much everything has been covered about cleanliness, etc., etc..
But if you are looking for "more", in the way of actual "Tricks".....this could get really technical ?
and,
probably far beyond what you would be able to DO yourself, or, access elsewhere for yourself, in a Home DIY environment ??

NOT trying to dis-courage you....but lots of "proprietary" stuff out there, best accessed through your Builder ?
Things like Crank overbalance factors, provisions to reduce #4 main hammering, Valvetrain Geometry & V/Spring Slew rates, Thermal Stabilization, ALL of it is useful, and ALL of it,
can start discussions, rife with as many opinions as ideas ?
