On my personal 440...no. My dad's street and strip cars and his drag car(chebbie ..gulp) as well as a couple buddies locally, yes. I've tuned with them. I've driven them, just not on a 440. I have driven a 408 stroker with a tunnel ram as well.
The reason I say what I do, is because I think the tunnel rams on a street car is way over kill. And at least on the ones I've been around, the amount of tuning and what it takes, I just don't think it works well on a street machine. however, every engine is different, one 440 built the exact same as another 440 down to the bolts, may very well react differently to a tunnel ram.
So if you have it, run it and if it works out awesomely for you, then that is great. :cheers:
However, my own experiences with them, I just can't recommend it. too much headache for no gain. But its merely my opinion, I'm no expert by any means. I wouldn't even pay 2 cents for my opinion either haha
