Their kits are good for the budget minded build, but you should always 
spend a few more bucks having the parts checked/corrected by a machine 
shop before using. I wouldn't consider any of it suitable to use 
out-of-the-box without being checked out. A nice step up would be the K1 
cranks and K1 or CompStar rods, especially if you consider the 
possibility of additional crank work that might be needed. I'd also get 
the balancing done locally.

I have one of Brandon's first run of 4.25 RB stroker cranks still 
sitting in my garage. It has .001" of taper across one main and .0005" 
across two others. A couple of the rod journals were .0004"-.0005" out 
of  round. This crank would have to be turned .010" in order for me to 
be comfortable using it in a 700+HP combo. 

P.S. The usual suspect will likely chime in to say that there is nothing 
wrong with those taper and roundness numbers. Each person has their own 
tolerances for acceptability in a given application.
