building a 512 atm from a rb, 440source kit. plan to use a similar cam (Howards 723445-08) for the same intended purpose.....the owner has got a indy dual plane intake i planned to use....do you think it will restrict it too much?

A dual plane intake isn't really required with a 512 since you can make 600 ft-lbs with a single plane. But on an engine like this it won't restrict it. Power peaks early on these engines anyway when the cam timing is small. I say try it and see how it works.
