This is a photo of a sbf flywheel and the portion of a front dampner for an external balanced 302 ---you can see how there is a differance in the amount of weight because of the distance from tyhe crank centerline


these next 2 are pics of early sbc flex plate for internal balance and next for a one piece seal crank with internal balance--the use of one piece seals doesn't allow for any offset flange weight in the rear




these two pics are of a flywheel for an sbc LT1 and you can see what the aftermarket flywheel uses compared to a weight off a factory flexplate
