415HP from 318ci IS POSSABLE!!

I had the cam already otherwise I would have opted for the roller.As far as rotating mass,I was refering to the 904 vs the 727.The sm blk mopar runs much quicker with the 904 behind it.And as far as the 360 being a pig,it was in the stock form I was refering to,although I still think the 318 magnum is the way to go dollar for dollar.Also,340's begining to become quite rare,The magnum 360 with the 318 magnum crank and bored .040 makes a killer package with the roller setup.Just a thought.
