NOS 3.51" mopar stroker crank in a 318?

I want to thank every body for the input, sorry to hyjack the original post just figured we might both learn a thing or two. presently there are 4 of these cranks on ebay going for a fair price, can not remember what I payed but it was cheep and new in the box. it is 8 bolt and the fex plate was easy to find. the rest is just eagle rods, the diamond custom pistons that I already have, fresh X heads, hughes special grind cam for this crank, and eddy Air gap manifold, Harland sharp rockers, and hughes hold downs. I do not trust many shops in my neck of the woods, and i drive past Phantom Works every day on the way to work, I am going to bring the build to north carolina nascar countryshop that only does mopars and has a 3 month back log on there builds, for the wait I will get a video on youtube of the breakin. Thanks again for the input.
