I like 409!i bet the GM engineers got a real kick out of that song with specific mention of the design features of the SS Chevy'"4 speed Dual quad(Rochester Quadrajet)positraction 409"!
All of the ducts have to be shrouded and the wheel vents have to have arched grilles.Much work ahead but it is looking like a race car.Much bigger than 1/25th!More like 1/16th!
