ok the info is mostly a V8 setup where the pistons have thrust in two directions the flatter the angle will affect the torque of the engine build flatter = more torque and thrust direction or main barring wear surface is wider this is why the inline six has a longer rod length the characteristics of a single direction of thrust id different then a V engine this with shorter rods is why V engines have higher RPMs and Inline engines have higher torque and lower rpm's if you build a inline six with shorter rods and change the bore to stroke ratio with bore bigger then stroke you can have a engine that revs up faster but will lose torque threw out the power band I want to build a high torque engine and keep the longevity the reason the 302 is so desirable is the build is square 4X4 " and the rod is 7" this is a high torque engine known for longevity my reasoning for a 8" rod is to use a lighter 4.125" piston and not change the stroke to gain CID and faster spin up but want to increase the torque threw out the power band
