well, the stroker kit costs about a grand, 2 demon carbs costs about a grand, everything on the 408 in the article i read is built with high end performance parts, but with a really really mild cam.

so i figure building up a 340 would be about $1500 cheaper

Unless you already own a 340 motor it will be cheaper to build a 360 because they are so much cheaper to start with. Also, the only additional cost to make a 408 from a 360 or a 416 from a 340 is the cost of the stroker crank which is $350 as Midnight mentioned.
