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.

HotRodDave I Live Here H Joined: Jan 2005 Posts: 12,419 Kalispell Mt.	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!
