340 street hp

I just put together a 72 340.
I am thinking about putting it in my duster.
The car is a 4-speed, 3.23 but I do have a 4.30 gear.
Specs on the motor are .030, cast crank, 243 KB, stock X heads, ld340 intake 700 holley dp, lunati 50403 .494/5.13 lift 271 /279 duration.
Just going to cruise around in this, have some good family fun.
What do you think hp wise this motor will make?
