this one would be the one I would pick from your list: CompCam#12-423-8 224/230 @.050 .535/.544 w/ 1.6's (roller cam) assuming you have at least 10.25:1 compression
get the lightest pistons and the longest conrods that will fit without putting the wrist pin into the
oil rings
I would get the edelbrock rpm heads over the vic jr heads(the vics kill bottom end)
but put a vic jr intake on there with a holley 780-850cfm doublepumper
Get an aluminum flywheel too, otherwise you will wish you had down the road.
These are loose guidlines, better you speak with a local machinest/engine builder who will put it together for you AND stand behind his work. There are a lot of little tricks on these motors, that cannot be fully gone into here.
