I like it, a little bigger than a 440 hp cam, should make a nice snappy street car.

 

It's in the range of the old Hemi cam, little bigger and smaller.

 

well...that sounds positive anyway.. thanks.

 

As long as the compression is good.... Should run decent.

 

I'd like to answer your question with one of my own. What would you like the cam to do? Like what is the goal for this cam swap? What cam is in there now? I think if you're already running the 440hp grind it won't be a big enough difference to justify the effort and expense. Just my two cents though
