- All Small Block Ford models are made to the early short length of 3". This allows the use of a late 5.0L engine with a 50 oz damper to be used in an early chassis where front clearance is at a minimum. To fit in late vehicles, we offer a series of spacers to provide the correct front pulley alignment. See Spacer Chart below.
- These Ford dampers also have three sets of timing marks and both 3 and 4-bolt accessory pulley bolt patterns. The plastic insert shown in the photos can be used to center 3-bolt pulleys with a female pilot, or it can be removed to accept 3-bolt pulleys with a male pilot.
