Is this cam to much for a stock engine?

Well, this is what Lunati says...

"This High Performance street cam likes 2400 RPM stall, 700 cfm carb, dual plane intake and headers. Makes un-equaled power to 6200 RPM with proper valve springs. Very strong cam with great street manners.
Advertised Duration (Int/Exh): 268/276

Valve Lash (Int/Exh): Hyd/Hyd
RPM Range: 1800-6200"


It sounds to me like you'll need valvesprings, bigger carb and a new stall convertor for this one to work decent in your combination. If you're already planning on doing some work to the heads I might just wait until then, after all you'll have it torn down about that far anyway. I wouldn't just toss that cam in that engine though, the valvesprings will not be happy for sure, and I doubt you'll see the advantages of that cam without some of the other mentioned upgrades.
