Flat Plane vs Normal V engine vs Inline vs rotary

i voted for the pancakes, because of their low center of gravity, beat only by the rotaries, which have absolutly gutless bottom ends.

A cross-plain V8 (typical american style V8) has crank pins every 90degrees of the crankshaft.

A flat-plain V8 has crank pins every 180degrees of the crankshaft.

Counterweights are added to a cross-plane V8 to counter the end-to-end vibration due to the last cylinder not being in the same position as the first one. This allows for the cross-plane V8's to run smooth, but the increased weight reduces their ability to rev.

Flat-plane V8s crank pins are arranged to that of a 4 cylinder engine which causes them to have stronger vibrations as compared to the cross-plane. The vibrations are reduced by using expensive lightweight materials such as pistons, etc. They are however; usually only used in sports cars due to their nature of being more responsive to throttle and their ability to rev vs. their rough idle and poor ride quality.

So another words to take you average v engine and make it a flat plane it would cost a pretty penney. Unless u decided no to change to lighter parts which would make a very rough idle.
