360 Magnum vs 340 mild street build - my experience

You are Comparing a engine with a better flowing head ( which the magnum has over 2.02 x heads) you could put a magnum head on a 340 and the hp numbers will jump or a cheap speed master head ( which would still outflow stock) . Apple to apple comparison would be comparing a la 360 with x heads .... In my eyes the only real value is in cost rather than performance 360 Magnums are just way cheaper and plentiful. People are not giving up their la blocks anymore ...
