Review: Rewarding engine build - Very large engine build. A lot of detail from crank shaft to cams, valves and timing chains. Realistic appearance. Interesting speed gearbox. This was challenging and instructions are good. Some parts need glue to hold in place.

Great gift for a gearhead who also loves their childhood memories of building blocks. Worth the money. Easy instructions to follow. Had all parts. Still holding up strong.
