Ok guys for us that remember 348's and 409's they was the hottest thing around next to fuel injection vettes. (vettes again) Anyway lets talk 409 more experience. Everybody and their brothers wanted one until they started to blowing them up. Don't get me wrong Mother in law had 64 Impala SS had well over 125,000 when she sold it.
They are very expensive to rebuild, thats why guys got fired up about 427's w/425hp you could buy it right from the factory. 454 has proven to be a really good truck motor, plus many options you can do with it. I do agree if you can get 1hp per cubic inch thats pretty cool especially inliners that can only repesent torque awesome.
Here in the midwest late 60's early 70's it was fun to figure HP to weight. popcorn The Truth is Out There (If I was rich I would sell my 350/340hp for a HEMI
)
