360 rebuild-low budget good power recommendations

I am planning on rebuilding my 1978 360 motor in the spring. Looking for a good setup now so I can start buying parts.
I had a decent 360 that my dad built 20 years ago. The one I have now is stock. The one my dad built was bored 30 over, had 8.8 piston-stock was 8.4 cr, original steel 340 4 bbl intake, mild cam-(Cam Dynamics part #150052 grind # 272 H10- 272 duration lift- intake @cam= 3027 at valve 454, exhaust @ cam same. 1.5 rocker ratio), set of hedman headers and the smaller 750??cfm thermoquad. I had then and now a stock 904 trans with lock up TQ and the rear is a 3.23 axle. I have front disc with large bolt rally wheels all around-15" rims in back with 14" up front.

Anyway-not looking for anything radical. That engine I had before was enough to kill 99% of the Mustangs then-early 90's. What I am looking for now is something that I can run on pump gas-works on 91 octane. Looking for 9:1-9.5:1 CR. I dont want a cam that will make me look like my car is bouncing at a stop light lol. Smooth idle to slight shake for cam. Basically a good sleeper car-looks nice, wont shake the car, but when you shove that gas pedal into the floor boards-all you see is my tail lights kind of car.

Needs to keep costs down but still want it done right. Mildly warm 360.
Give me some ideas. I also want to possibly add 150 shot of laughing gas sometime down the road.
