In regards to the original question.
"Why build a stroker if not racing..."

There isn't a practical explanation. It's because we 'like' it. It's that simple.

If our only goal was to go fast in the most practical way possible, we'd all be driving used LS Corvettes. But we don't, because we like Mopars. We build Hemi strokers for the street because we like them, not because they make sense.

I built a 528 Hemi with iron heads for the street. It has somewhere between 10 and 15 thousand miles on it and uses oil the same way other have described, about quart low and then it's fine. It has a tiny stock style cam and 10:1 compression. If you're fine with how your car drives already, I wouldn't stroke it unless you just plain want to.
