30 over is 406.77 cubes, 40 over is 408.73, 60 over is 412.67.

What you call it just depends on whether you round the decimal up or down

Yep basically same thing. Just like Eric depends on which way you go with the #s. 408 - 409

Call what you have a 409 around any oldtimers and you will get a bunch of peeved looks and an earful of static when you pop the hood, the Chevy BigBlock 409 W engine was an iconic performance legend in the early 60's

Thats the first thing that entered my mind when he said 409. the BigBlock 409 W with those funkyfide valve covers i love the looks of that old engine.
Now go and get yourself some cheap sunglasses. Quoated from the great sounds of ZZTOP

If you've seen any of the modern renditions of the 409 W head now that there are a couple of different aftermarket aluminum heads available for them it might change your tune. very powerful and high revving stuff due to the big bore(bigger than 454 BBC) and short stroke. Some of these running in Nostalgia classes are pretty wicked, make a BBC think twice

Couldn't find a price. You can call for one. Based on other prices I am guessing $12K.

You can pick up an aluminum 409 block for just a bit over $5.5K.

Add the aluminum heads on the market and you have a lightweight piece of nostalgia. Up to 540 cubes IIRC.
