40 Years Of 348 And 409 W-Engines - W-ow!
|
The very rare 1962 Z11 409 engine components included a high rise, two-piece, aluminum intake manifold, heads with much taller intake ports (very similar to big-block rectangle ports) and stock 409 carbs. The camshaft had more valve lift, but the duration was still short for a strong mid-range. Note the crinkled, aluminum inner fenders. They were 1962-only, as the aluminum was so thin, it rolled over and wadded up in the actual die/mold. View Related Article
