Best 273 and 318 builds (NO 360's please)

Ive been thinking about taking the 5.9 out of my car to have done up into a stroker motor.

In the meantime (and with the kids in school, there will be a meantime) I thought about doing this as a stunt:

take my stock '71 318 shortblock (maybe put rings/hone in it, cylinders are ok)
Put on my 1.9 valve EQ/Iron RAM heads
RPM Air Gap intake
Cam? (would have to know my final comp ratio to make a smart choice, pistons are .100 in the hole...)
1-5/8 headers to 2.5 X-pipe
good oil pan
fresh paint
"yeah, its got a 318" bumper sticker

I've got decent chassis parts on the car, Calvert shocks, Caltracs.

The car does pretty well with the 5.9. Mid-high 1.5 60' times, about 3400 lbs, runs 11.70s with about 320 rwhp.

Any input on what the 'teen would pull off with that combo? Whatever I come up with feels either wildly optimistic or pessimistic.
