2250EH Series (2-1/4" OD) NEW!!
These blocks, molded in red ABS plastic, are available in 4 different shapes to aid in modeling custom exhaust headers using 2-1/4″ OD mandrel bent tubing: 1″ straight, 3” CLR (centerline radius), 4” CLR, and 6” CLR. Pro Kits include enough blocks 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 2-1/4” OD tube to start the tubular assembly design started either downstream or upstream.
