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.
