Greg - you should have added in what year Regal. My thought would be to stay with the olds family and go straight up to a 403 - not the "big block", but the 403 small block Olds. My parents 77 Electra had a 403 in it, and they can be built to be very serious performers - it should bolt right in to the 307's current spot and to the trans as well. The 403 can dish out some serious torque.
As for the 307, it can be a halfway decent performer - it has about as much potential as a chevy 305, except with better torque potential. You can swap in a decent cam, swap to an Edelbrock intake, and if you have enough cash - you can port/polish/shave the heads for some more compression. If you go this route, remember that you want to shoot for a long, flat torque curve - if you build for high hp numbers you'll only make your Regal a slouch off the line.

i think your idea of building the 350 would be my choice.
just be sure not to over build it, which you will be tempted to do.
