Cam ? Too big for my iron 5.7 build?

Stall around 3400? And some 7.3 rods? I might hold off on such a large cam then.

To get the exact length pushrods you will need get a pushrod length tool. That will tell you exactly what length to get so there is no guessing of the base circle of the cam and how much is milled from the heads.
