Trying a lil different combo on my 318 ...

when I spun my 273/4 con rod bearing, I dropped in a 318 short block. Same 65 heads, went with a Herbert stage 2 cam (CE2N 205/215 [email protected], 425/445, 112LC, 1000-5000 close to a 340 auto I suppose) and a performer intake, (wallowed out holes and everything). That motor kicked *** in that light car. So your 318 that thinks its a 340 in 273 dress may be just fine.
