Usable power for the street?

Hey everyone, first off, I really appreciate all the feedback I get on this forum. I really value your opinions, so I’m coming back with another question…

What do you consider good steerable power?

I currently have a 273 Charger motor (1967) and an 833 4 speed trans for my ‘67 Barracuda (unknown rear gears).

I’m not looking to race the car, but do want to be able to break the tires loose easily from time to time and launch hard. I keep hearing people tell me “get a 360 if you want power.” From my reading, a mildly built 360 can make about 350 hp (cam, intake, headers).

Is that getting to be overkill for a street car?

I’ve never been in a car with a 273 Commando, so I don’t have any point of reference aside from what I’ve read. I know the common adage is always “more is better,” but I’m curious to hear what your thoughts are.

In my area, I can buy a running 5.9 magnum for around $700, after dressing it with a carbureted intake, cam, headers, and new carb, I’m nearing $2300… while I can have my 273 together for around $1700 (boring cylinders, a new cam/lifters).

Thanks again everyone, you guys really help me with these decisions.
