As far as rods go, either the C6AE-C or C7AE-B castings are great for hot street machine use. The 428 CJ rod was a C7AE-B casting that were drilled out to accept a rod bolt that was 1/32" larger than the standard 3/8" bolt.
They did not have ARP bolts back then so drilling out for a larger bolt was the only way to make the rod stronger. Just install a set of ARP 3/8" rod bolts in the standard rods. You will have a rod that is stronger than the CJ version with the larger bolt.
I personally would not run a cam that I had no idea what the specs were. Spring for a new cam and purchase the recommended valve train accessories.
I would balance the motor. I do for all the performance motors that I build.
Don't scrimp on trying to reuse 30+ year old wear parts. 428CJ's dont grow on trees anymore. You're lucky to have those spare parts.
To illustrate, a guy that I know runs a 428SCJ in the local drags. During one run, he lost a main cap bolt and blew the block. He was trusting factory orignal bolts that had been torqued and retorqued many times over the life of the motor.
Nuff' said for now. Hope this gives you some ideas!
