I think a lot of people just think they have to have a stroker b/c kits are everywhere nowadays. But if you already have a good rotating assembly, aren't interested in seriously racing, don't have a low ET goal, and just want a fun street car...stick w/ the stock crank. Unless you just like wasting money.
I'm not knocking a stroker at all, they're great. I just think too many people are discounting just how strong a well set up stock stroke motor can run. Doesn't take all that much to really wake one up.
For the OP's intended use, I think a stroker kit is an absolute waste of money.

Oh, a 9:1 hemi should be able to run on 87 octane. I'd go 10.5:1 at the absolute minimum.
