1625 Series 20 Piece Add On Set- Any Ratio

 

expand your modeling capabilities with add-on kits
As you begin to design with the icengineworks^TM modeling blocks, you will begin to see new possibilities that were not evident before. These ideas may require additional blocks but not as many to justify the purchase of a new complete engine kit. Our Add-on modeling block sets will help you complete those new design variations that will lead to superior exhaust header systems. Maybe you want to begin researching a one- or two-stage stepped design, or want to graduate your original V8 modeling block engine kit into a V12 set, or simply you want to replace a few worn out or lost units. Whatever the reason you have to use them in more than one way, they are available in many combinations. Each Series page includes its Add-On sets.
