1625EH Series (1-5/8 OD)

The icengineworks 1625EHSeries blocks are molded in blue ABS plastic and are available in 4 different shapes to aid in modeling custom exhaust headers using 1-5/8″ OD mandrel bent tubing: 1″ straight, 2” CLR, 3” CLR, and 4” 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 1-5/8” OD tube to start the tubular assembly design started either downstream or upstream.
