STEM V8 Engine Model Kit Adults

A precision-engineered V8 small block motor model kit tailored for adult learners, educators and automotive hobbyists. Compact footprint (12.5 x 8.2 x 7.3 cm), lightweight at 420 g, yet densely detailed with functional moving parts: crankshaft rotates freely, pistons reciprocate in sequence, and rocker arms follow cam lobe profiles. Constructed from robust ABS plastic with metallic-tone accents on valve covers and intake manifold. All surfaces are injection-moulded with fine surface finish — no sanding or finishing required. Assembly introduces core mechanical concepts: stroke length vs bore diameter, compression ratio implications, valve overlap timing, and harmonic balancer function. Instructions are bilingual (English only in this version), fully illustrated and annotated with engineering callouts. Completed model mounts securely on included acrylic base for stable display. Designed for repeated interaction — ideal for explaining engine fundamentals during tutoring sessions, workshop demos or casual learning at home. Not intended for children under 14 due to small parts and fine motor requirements.
