There's nothing magical about a 340. I'd rather start with a 360. More plentiful, less expensive. 20 more cubes is a bonus.

If the 340 was so great why did Mopar can it and continue building the 360 in the middle 70s...?

I'm not siding with the 340, but it's my understanding that it was discontinued in favor of the 360 for emissions reasons. Smaller bore produced less emissions with a more complete burn.
'73 340 vs '74 360 is the best comparison. Only bore & stroke is different & 360 wins. Only other variables would be state of tune and the rest of the car. 340's do like a little more gear, but I can't see that being a dominant factor.

I would love to see someone bolt a bone stock hi-po 340 on a dyno with an air gap intake and TTI headers, then strap an air gap on a 360 magnum and the same TTI headers and watch the 360 make more power at EVERY RPM. The 73 340 VS 74 360 is also a great example, when outfitted the same way the 360 puts the hurting on it real bad. Also the 360 mag has a stronger block and a hydro roller cam you can get reground to a real nice cam under $100. How much does it cost to put any roller cam in a 340? I have a real nice 71 340 with a fresh .030 bore job that I am gonna pass on building for my R/T Dak because I want to make 550-600 HP that will last a long time. It is a tough decesion because of the cubes I will give up but 8 cubes is nothing compared to a roller cam and a more solid block The 360 wins in every case except a numbers matching gold restoration type build.
I am not causing global warming, I am just trying to hold off a impending Ice Age!

Until you sonic test a 340 and realize they can be paper thin!
