The SB Ford '80 and later 5.0L Harmonic Damper boasts more universal features than any other damper. All SB Ford models are crafted to the early, shorter length of 3 inches, enabling the use of a late 5.0L engine with a 50 oz-in damper in early chassis with limited front clearance. For compatibility with later vehicles, we provide spacers to ensure proper front pulley alignment. Additionally, these Ford dampers feature three sets of timing marks and are compatible with both 3 and 4-bolt accessory pulley patterns. The included plastic insert can center 3-bolt pulleys with a female pilot or be removed to fit 3-bolt pulleys with a male pilot, making these dampers exceptionally adaptable for various Ford engines.

Sound good, fits mediocre

Doesn't REALLY fit a 2010. The muffler tips are recessed into the bumper. It needs a 1 - 2" extension to fit a 2010 well. It bolts up, yeah, but it doesn't actually get the exhaust out past the bumper because the 2010 dimensions are a bit different than the pre-2010 S197s,

Can’t go wrong !

Great FE Balancer. Used on 3 builds, 427 & 2 -428’s.

On a LS with 20lbs boost

I got these for my mechanic. He has a LS with an 88mm turbo on 20lbs. Wires look great and perform great.

Great fitment

Fits great. I wish they had written in BOLD a reminder to put RTV around the coolant ports on the gaskets, because you know, I had to do it twice. This intake looks great and is superior to the Edelbrock, if you want it to last more than half a dozen years. They tie the rear coolant ports together with a passage that Edelbrock just blocks off. Electrolysis goes to work and rots the E-B. Again, this is a much superior design to convert a 5.0 HO fuel injection to carb.
