I personally would go with a 4.250, and yes, when you add 30-60 cubes, the cam selection will change. The cam you have will be much milder with a larger engine. If that's something you can deal with, then no need to change. Also no problem with mixing manufacturers if you do change.
Save the $500 that you would spend on a steel crank, get a cast 4.25 stroke, and buy a new set of rods and piston rings with the money.

Doug, you should listen to Brent, he's much brighter than I am on these matters.  But, I will throw this in: I know you're younger than I am (because I've met you) and I know you run your car harder than I do mine (because you break it every couple of years). If you don't want to do all of this again, err on the side of "less is more" on your rebuild. A slightly shorter stroke, slightly less cam lift, and slightly less power, will let your engine live longer and, that way, the next "major rebuild" will be undertaken by your heirs.  |

Gonna call you out on the stroke part.
I'd put a 6" stroke in if it would fit.
Absolutely zero issues with longer stroke.

Well, alright... but you're still brighter than I am. |

Brighter? Nope. I just have more experience than you in engine building and that's to be expected since that's what I do.
Wouldn't know where to start on lawyer'in.

So would you leave the cam alone? I know it's not the most efficient profile, but I do like the sound and feel of it quite a bit. BUT, if I'm going to do it, I'd rather do it now and I'm not against more power although no one really needs it in these cars...
