Where's the 340 crate engines???

Not going to happen. I'll tell ya why. Recasting the 340 block is one thing and they made it so. Did you see the price????????
Now add a asemble to that order and the more expensive internal balancing.

The current 360, dispite what you'll rant and rave on about the 340, is;

20 inchs larger
cheap
readliy avilable to use
Made much much cheaper.

Also, the 273-318-340-360 engines are not a "Semi HEMI" but the earlier 318-301-277 poly engines are called that. They have a canted valve design.
Theres no such thing stock as a 340 semi hemi.
