Ditch the vacuum tubes and welding wire! The 1750 Series modeling blocks allows builders to quickly mock up exhaust headers to test fitment before cutting any expensive metal. These blocks will make fabrication a breeze and reduce labor time by as much as 75%. You need only to fit the engine in place with flanges, starter tubes and exhaust collectors. If you don't have the collectors yet, you can use Collector Dummies. Sold in sets per SERIES (tubing OD specific).
To help you make precise cuts, reducing labor and material costs, Cutting Spacers (CS)are available for 3", 4" and centerline radius (CLR).
