duration /valve overlap determines how agressive the lope will be

so the higher the duration and valve over lap the more aggressive?

probably squeeze with the right combo 270 to 280 rwhp out of a sd car......cause at the range you'll be pushin the 19 lb injectors close to their max duty cycle and for more hp after that you'll most likely need a sd tunner to alter tune for larger injectors

you will have to lose the stock ecu and go with an aftermarket like megasquirt or xfi.
