426 stroker kit opinions?

As they say, just because you can build something, doesn't mean you should.
I put a 4 inch arm in my 340 and I absolutely love it. It's in my Roadrunner right now and it flat moves the car like there was a lightweight big block in it. I have a shot at a 440, which I am seriously considering, but I like the way the whole package works right now. But, then again, that hyper little stroker in my 2800 lbs. Valiant would be extremely dangerous. Well, I guess we all know what I am going to do.....

Revhendo.
