(Oversquare is bore vs. stroker, for instance 4.030 x 3.750 (383) vs 4.125 x 3.750 (400) vs 4.000 x 4.380 (350), etc) 400 heads also have steam holes in between ...you would have about 10.5:1 with a 350 but closer to 11.4:1 with a 383, theres 43.75 cubic inches of volume in a 350s cylinder and 47.8 cubic inches of volume in a 383s cylinder. it should be rather obvious that increasing the compression changes the fuel octane requirements.Just doing the math, compression is worth about 2% per point. The cu in difference would be worth about 22 lb ft of torque, all else considered. I'll let you decide if it's worth it. RevTheory. Guru. Posts: 5646. Joined: Thu Sep 04, 2014 10:45 am.
