You probably don't want to hear it, but I'd find a 460 crank and the proper pistons. The cranks are very cheap and you need new pistons anyway for a proper build so it shouldn't be that expensive. From there, I'll tell you the combo that my Dad and I put together from an old Super Ford magazine, pulled 430hp at 5000rpm and 530lb-ft at 3900. 750cfm Holley, Performer intake, 9.5:1 pistons, DOVE heads (you have them already) with 2.19/1.75 valves and thermactor bump removed. .518/.513 272/284 duration cam and 1 7/8" headers. Should be pretty close to what you want for your application, and it's pretty inexpensive to build.
