1875EH Series (1-7/8 OD)
These blocks, molded in green ABS plastic, are available in 6 different shapes to aid in modeling custom exhaust headers using 1-7/8″ OD mandrel bent tubing: 1″ straight , 2” CLR (centerline radius), 2.5” CLR, 3” CLR, 4” CLR, and 5” CLR. Pro Kits include enough pieces to simultaneously model both sides of a V8 engine, whereas Basic Kits should allow one side at a time. Kits also include block adapters to be attached to the open end of a 1-7/8” OD tube to start the tubular assembly design started either downstream or upstream.
