It is really all relative to what equipment you have in on and behind the 350.
I think you went the wrong direction, the 327 and 350 have the same bore and block actually, the crank in the 327 has a 1/4" shorter stroke than a 350 so you will loose some torque compared to the 350. You can use a 400 crank with a 1/4" more stroke than the 350 crank, then you GOT torque!
