440 engine mod help

That's COMP's version of the 375hp 440 magnum cam isn't it? Ought to run pretty well I'd imagine

No, that's a bit bigger than the stock 375hp cam. I've got something similar (Mopar cam) in a similar 440, but it's nowhere near ready to go in the car so I cannot comment on how it runs. My pistons are about .180 in the hole...
