A couple notes on 440 Source kits from years of using them...
You need to measure everything on that crank. The cranks are generally in spec but will have taper on them - if your builder is particular he may balk. I've used about 10 kits and I've never had a crank I couldn't use - but a couple were at the bad end of the "ok" spectrum. The rods need to be cycled and torqed with ARP lube, then checked for size and the pin bushings should be honed because they're usually rather tight. Please don't "just use emery paper". I just budget to have the rods "fixed". Also - have your local performance shop balance the assembly - not Source.
