The problem with running low tension (about 5 to 10 pounds) or very low tension (3 to 5 pounds) with an engine that draws a strong vacuum is the possibility of increased oil consumption.
Gassers that do run low or very low tension usually run vacuum pumps (maintain no more than 8 to 10 inches of Hg).
There is a new dodge that runs low tension rings but the block has been engineered to maintain bore roundness through heating cycles and many thousands of miles of driving.

The only way we can get close to that engeering is to have your block machined while torqued with a deck plate, mains torqued and block heated to near operating temperature.
