440 build will it work

They make 2 different Mopar 484 cams. One on a 108 cl, which has a good lope, and the 114 cl to smooth it out for better street manners.

I have the 108 cl cam in a 440, has a good sound at idle.

I agree on the bigger valves. I have stock valve size in my 440 and wish I had put in the 2.14 1.81. But I hope to swap on some Edelbrocks one day.

It will still run good, just be smoother running with cam you have.
