We designed these Ford Cleveland 2 port CNC machined billet spacers to allow the use of Pacemaker off the shelf extractors to be used with Dart & World aftermarket blocks. Without this spacer the extractors will not clear the block on cylinders 2 & 3. This spacer will give you the clearance required to fit 1 7/8″ or 2″ extractors. The port openings are machined to suit “3V” High port exhaust ports, but can also be ported to suit factory 4V exhaust ports if required.
One spacer is required per engine.
