Too much horsepower?

With what you have for heads, I'd be very surprised to see that hit anything more than around 650, depending on the mid-lift figures. You need more duration to really let the heads work and get big numbers. You also really cant compare to Stock or Super Stock. They are an entirely different animal. Put it together and dyno it. Then worry if needed. I really dont think you'll need to sweat it much. (not meant as a cut, just going on info provided)

I understand what you're saying. I never say I know it all but I do know a good bit. You seem to be a knowledgable guy from what I read from your posts. I know a lot of the the Stock, Super Stock stuff, I've known these guys for decades.They didn't use this cam because it didn't make enough HP. I'm not saying I'm building my junk to SS level but my heads and induction system are much better than what they have to use.

I was only looking to make 650-660 HP with this motor. I was just blown away by what the sims spit out and then what I was told that cam made in their engine so if it does come close I'm probably going to be in trouble. :)
